Randomised clinical trial of lensectomy versus lens aspiration and primary capsulotomy for children with bilateral cataract in south India. (1/51)

AIMS: The primary objective was to determine which surgical technique gave the best long term visual outcome for infants and young children with bilateral symmetrical cataract in south India. Secondary objectives were to assess complications and the need for further surgical intervention. METHODS: A randomised controlled clinical trial was undertaken. 65 children under 10 years old with bilateral cataract had one eye treated by lensectomy and the other by aspiration with primary capsulotomy. RESULTS: 56 children (86%) with a mean age at surgery of 53 months were reviewed 3 years after surgery. The overall binocular acuity was 6/18 or better in 57.1% and 6/60 or better in 94.6%. There was no difference in visual acuity between the matched pairs of eyes undergoing aspiration or lensectomy at the third year of follow up (p=0.57). Aspiration eyes were more likely to require a secondary procedure to restore vision than lensectomy eyes (66.1% v 1.8%). CONCLUSION: Aspiration with primary capsulotomy gives an acceptable visual outcome in this part of India providing that there is good follow up to manage capsule opacification. If secondary intervention is not possible owing to poor compliance with follow up, then lensectomy is likely to give better long term visual rehabilitation providing there is good maintenance and technical support for the lensectomy equipment.  (+info)

Two cases of late postoperative capsular block syndrome. (2/51)

Two cases of late postoperative capsular block syndrome that occurred 4 and 8.5 years, respectively, were encountered. One case underwent phacoemulsification after continuous curvilinear capsulorhexis in his left eye. The other case had a can opener type capsulorhexis and underwent extracapsular cataract extraction with trabeculectomy. One-piece posterior chamber lenses were implanted in both cases. Upon slit-lamp examination, the posterior capsules were found distorted posteriorly; the capsular openings were apparently sealed by the lens optic. A whitish material existed between the intraocular lens optic and posterior capsule, with thick aggregation in a lower fifth space in case 1. After Nd:YAG laser anterior capsulotomy in case 1, the thick aggregate spread diffusely on the posterior capsule which was sunken completely for 4 weeks. After Nd:YAG capsulotomy, the distorted posterior capsule disappeared and the best corrected visual acuity was restored to 20/20 in both cases.  (+info)

Quantitative measurement of the PCCC area in the postoperative period. (3/51)

BACKGROUND/AIMS: The major complication of extracapsular cataract extraction (ECCE) is posterior capsule opacification (PCO). Posterior continuous circular capsulorhexis (PCCC) seems to be very promising in preventing PCO. This study was aimed at determining if the PCCC area changes as a function of time and if pearl formation could influence it. METHODS: 24 eyes of 23 patients underwent ECCE with PCCC. Retroillumination photographs were taken at 6 months and then yearly. To measure the PCCC area, the computerised program EPCO (evaluation of posterior capsule opacification) was used. The ratio of the PCCC area in relation to the IOL surface was calculated for the different time stages and the presence of pearl formation was noted. Firstly, proportional changes in diameter were compared in PCCC areas measured after 6 months and after 1 year (group I, n=13) and after 1 year and 2 years (group II, n=14). Secondly, PCCC areas were compared between two time stages in patients with (group III, n=19) and without pearl formation (group IV, n=8). RESULTS: No statistically significant difference was found in diameter change in either group. The PCCC area remains stabile between 6 months to 1 year and 1 year to 2 years. No differences are found between eyes with or without pearl formation. CONCLUSIONS: The PCCC area remains stable as a function of time and is not influenced by pearl formation.  (+info)

Towards achieving small-incision cataract surgery 99.8% of the time. (4/51)

A surgical approach designed to reliably attain the modern goal of small incision cataract surgery 99.8% of the time is described. Phacoemulsification as well as a manual small incision technique is utilised to achieve the desired outcome as often as possible and for all types of cataracts. The logic, and required surgical steps are described and illustrated. This surgical technique allows the advantages of small incision surgery to be reliably achieved. The method is flexible and allows decisions and steps to be modified depending on the skill and comfort zone of the individual surgeon.  (+info)

In vitro study on the closure of posterior capsulorrhexis in the human eye. (6/51)

PURPOSE: An unexplained clinical observation is the development of posterior capsular opacification (PCO), even when the central part of the posterior capsule has been removed. The purpose of this study was to investigate in vitro the mechanisms involved in the closure of the posterior capsulorrhexis in a capsular bag model. METHODS: A sham extracapsular cataract extraction was performed in 71 human donor eyes, followed by a central posterior capsulorrhexis 3 to 4 mm in diameter. Each capsular bag was pinned to a PMMA ring with a central hole of 5 mm and placed in a Petri dish. The capsular bags were cultured and monitored for 3 to 7 weeks by phase-contrast microscopy, after which they were prepared for light, transmission, and scanning electron microscopy. RESULTS: Proliferation of lens epithelial cells (LECs) within the posterior rhexis area was found in 22 cases (31%) of which 3 had a complete closure. In the absence of the posterior capsule, a monolayer of LECs was observed growing on a basal lamina, consisting of loosely arranged fibers. Further observations on noncultured capsular bags revealed that this basal lamina corresponds to the anterior hyaloid membrane. CONCLUSIONS: This study corroborates the clinical observation that LECs that remain after cataract extraction have the potential to proliferate, in the absence of their natural substrate, on a basal lamina of vitreous origin and are able to close the posterior capsulorrhexis partially or totally in approximately one third of cases.  (+info)

A new model of posterior capsule opacification in rodents. (7/51)

PURPOSE: To describe a new model of posterior capsule opacification (PCO) in rodents METHODS: An extracapsular lens extraction (ECLE), by continuous curvilinear capsulorrhexis and hydrodissection, was performed in 42 consecutive Brown Norway rats. Animals were killed at 0, 6, and 24 hours and 3, 7, and 14 days after surgery. Eyes were enucleated and processed for light microscopy and immunohistochemistry. RESULTS: In 34 (81%) of the animals the operated eye appeared well healed before death, with a clear cornea and a well-formed anterior chamber. In eight (19%) there was no view of anterior segment structures because of hyphema, fibrin, or corneal opacification. PCO was clinically evident 3 days after ECLE and was present in all animals at 2 weeks. Immediately after ECLE, lens epithelial cells (LECs) were present in the inner surface of the anterior capsule and lens bow. Twenty-four hours after surgery, LECs started to migrate toward the center of the posterior capsule. At 3 days, multilayered LECs, some spindle shaped, were present throughout the lens capsule. Capsular wrinkling was apparent. Lens fibers and Soemmering's ring were observed in all animals 14 days after surgery, indicating some degree of cellular differentiation. Activated macrophages were present in greater numbers at 3 and 14 days after surgery (P < 0.05), when proliferation and migration of LECs appeared to be greatest, and lens fiber differentiation was evident, respectively. CONCLUSIONS: In rodents PCO occurs after ECLE and is associated with low-grade inflammation, mostly of mononuclear macrophages. Although no intraocular lens implantation was performed, this model appears to be valuable for studying the sequence of events that leads to PCO after cataract surgery and the extracellular matrix cues that promote lens fiber differentiation.  (+info)

Cost analysis of cataract surgery with intraocular lens implantation: a single blind randomised clinical trial comparing extracapsular cataract extraction and phacoemulsification. (8/51)

A randomised single blinded clinical trial to compare the cost of cataract surgery between extracapsular cataract extraction (ECCE) and phacoemulsification (PEA) was conducted at Hospital Universiti Kebangsaan Malaysia (HUKM) between March and December 2000. A total of 60 patients were included in this study. The cost of a cataract surgery incurred by hospital, patients and households up to two months after discharge were included. The costs of training, loss of patients' income after discharge and intangible costs were excluded. Results showed that the average cost for one ECCE operation is RM1,664.46 (RM1,233.04-RM2,377.64) and for PEA is RM1,978.00 (RM1,557.87-RM3,334.50). During this short period of follow up, it can be concluded that ECCE is significantly cheaper than PEA by an average difference of RM 313.54 per patient (p < 0.001). Cost of equipment and low frequency of PEA technique done in HUKM were the two main reasons for the high unit cost of PEA as compared to ECCE.  (+info)

*Ishihara test

Being a printed plate, the accuracy of the test depends on using the proper lighting to illuminate the page. A "daylight" bulb illuminator is required to give the most accurate results, of around 6000-7000K temperature (ideal: 6500K, Color Rendering Index (CRI) ,90), and is required for military color vision screening policy. Fluorescent bulbs are many times used in school testing, but the color of fluorescent bulbs and their CRI can vary widely. Incandescent bulbs should not be used, as their low temperature (yellow-color) give highly inaccurate results, allowing some color vision deficient persons to pass. Proper testing technique is to give only three seconds per plate for an answer, and not allow coaching, touching or tracing of the numbers by the subject. The test is best given in random sequence, if possible, to reduce the effectiveness of prior memorization of the answers by subjects. Some pseudo-isochromatic plate books have the pages in binders, so the plates may be rearranged ...

*Ophthalmoscopy

Dr. William Cumming in 1846 at the Royal London Ophthalmic Hospital (later Moorfields Eye Hospital), of his pioneering work wrote "every eye could be made luminous if the axis from a source of illumination directed towards a person's eye and the line of vision of the observer were coincident".[2] Although some credit the invention of the ophthalmoscope to Charles Babbage in 1847, it was not until it was independently reinvented by Hermann von Helmholtz in 1851 that its usefulness was recognized - it was to revolutionize ophthalmology.[3] While training in France, Andreas Anagnostakis, MD, an ophthalmologist from Greece, came up with the idea of making the instrument hand-held by adding a concave mirror. Austin Barnett created a model for Anagnostakis, which he used in his practice and subsequently when presented at the first Ophthalmological Conference in Brussels in 1857, the instrument became very popular among ophthalmologists. In 1915, Francis A. Welch and William Noah Allyn invented the ...

*Photorefractive keratectomy

The U.S. Federal Aviation Administration will consider applicants with PRK once they are fully healed and stabilized, provided there are no complications and all other visual standards are met. Pilots should be aware, however, that potential employers, such as commercial airlines and private companies, may have policies that consider refractive surgery a disqualifying condition. Also, civilians who wish to fly military aircraft should know that there are restrictions on those who have had corrective surgery. The Army now permits flight applicants who have undergone PRK or LASIK. Uncomplicated, successful corneal refractive surgery does not require a waiver and is noted as information only.[21] The Navy and Marines will routinely grant a waiver for pilots or student naval aviators, as well as naval flight officers, UAS operators and aircrew, to fly after PRK and LASIK, assuming preoperative refractive standards are met, no complications in the healing process were encountered, asymptomatic with ...

*Corneal transplantation

Endothelial keratoplasty (EK) has been introduced by Melles et al. in 1998. Today there are three forms of EK. Deep Lamellar Endothelial Keratoplasty (DLEK) in which the posterior part of the recipient cornea is replaced by donor tissue. Descemet's Stripping (Automated) Endothelial Keratoplasty (DSEK/DSAEK) in which the diseased Descemet's membrane is removed and replaced by a healthy donor posterior transplant. The transplant tissue can be prepared by a surgeon's hand or ordered already prepared for surgery. Ocular Systems was the first organization to deliver prepared grafts for surgery in 2005.[20] DSEK/DSAEK uses only a small incision that is either self-sealing or may be closed with a few sutures. The small incision offers several benefits over traditional methods of corneal transplant such as Penetrating Keratoplasty. Because the procedure is less invasive, DSAEK leaves the eye much stronger and less prone to injury than full-thickness transplants. New medical devices such as the EndoSaver ...

*Surgery

After completion of surgery, the patient is transferred to the post anesthesia care unit and closely monitored. When the patient is judged to have recovered from the anesthesia, he/she is either transferred to a surgical ward elsewhere in the hospital or discharged home. During the post-operative period, the patient's general function is assessed, the outcome of the procedure is assessed, and the surgical site is checked for signs of infection. There are several risk factors associated with postoperative complications, such as immune deficiency and obesity. Obesity has long been considered a risk factor for adverse post-surgical outcomes. It has been linked to many disorders such as obesity hypoventilation syndrome, atelectasis and pulmonary embolism, adverse cardiovascular effects, and wound healing complications.[11] If removable skin closures are used, they are removed after 7 to 10 days post-operatively, or after healing of the incision is well under way. It is not uncommon for surgical ...

*Electrooculography

... (EOG) is a technique for measuring the corneo-retinal standing potential that exists between the front and the back of the human eye. The resulting signal is called the electrooculogram. Primary applications are in ophthalmological diagnosis and in recording eye movements. Unlike the electroretinogram, the EOG does not measure response to individual visual stimuli. To measure eye movement, pairs of electrodes are typically placed either above and below the eye or to the left and right of the eye. If the eye moves from center position toward one of the two electrodes, this electrode "sees" the positive side of the retina and the opposite electrode "sees" the negative side of the retina. Consequently, a potential difference occurs between the electrodes. Assuming that the resting potential is constant, the recorded potential is a measure of the eye's position. ...

*Optokinetic drum

An optokinetic drum -also called catford drum- is a rotating instrument to test vision in which individuals are seated facing the wall of the drum. The interior surface of the drum is normally striped; thus, as the drum rotates, the subject's eyes are subject to a moving visual field while the subject remains stationary, this phenomenon is called optokinetic Nystagmus. The speed of the drum and the duration of the test may be varied. Control groups are placed in a drum without stripes or rotation. After exposure to the rotating drum, subjects are surveyed to determine their susceptibility to motion sickness. A study in which the optokinetic drum was used to test the symptoms of the sopite syndrome showed increased mood changes in response to the visual cues, though these effects were compounded by other environmental factors such as boredom and lack of activity.[1] ...

*Electroretinography

... measures the electrical responses of various cell types in the retina, including the photoreceptors (rods and cones), inner retinal cells (bipolar and amacrine cells), and the ganglion cells. Electrodes (DTL silver/nylon fiber string) are usually placed on the surface of the cornea for Full Field/Global/Multifocal ERG's and brass/copper electrodes are placed on the skin near the eye for EOG type testing. During a recording, the patient's eyes are exposed to standardized stimuli and the resulting signal is displayed showing the time course of the signal's amplitude (voltage). Signals are very small, and typically are measured in microvolts or nanovolts. The ERG is composed of electrical potentials contributed by different cell types within the retina, and the stimulus conditions (flash or pattern stimulus, whether a background light is present, and the colors of the stimulus and background) can elicit stronger response from certain components. If a dim flash ERG is performed ...

AIM: To compare visual prognoses and postoperative adverse events of congenital cataract surgery performed at different times and using different surgical approaches. METHODS: In this prospective, randomized controlled trial, we recruited congenital cataract patients aged 3mo or younger before cataract surgery. Sixty-one eligible patients were randomly assigned to two groups according to surgical timing: a 3-month-old group and a 6-month-old group. Each eye underwent one of three randomly assigned surgical procedures, as follows: surgery A, lens aspiration (I/A); surgery B, lens aspiration with posterior continuous curvilinear capsulorhexis (I/A+PCCC); and surgery C, lens aspiration with posterior continuous curvilinear capsulorhexis and anterior vitrectomy (I/A+PCCC+A-Vit ...
The purpose of this study is to examine the efficacy of a capsular tension ring (CTR) in preventing anterior capsule shrinkage after cataract surgery in exfoliation syndrome (XFS) with no zonular weakness. The eyes with XFS undergo phacoemulsification and aspiration (PEA) with an intraocular lens (IOL) implantation. All operations are performed by a single surgeon. No eyes with either ectopia lentis or phacodonesis are included. There are three groups; CTR is not used in group A, CTR is simply implanted in group B, and CTR is implanted and closed by tying both eyelets in group C. The areas of continuous curvilinear capsulorhexis (CCC) are calculated, and both the time-course change and the comparison among the 3 groups are tested ...

Results Data collection ran from June 1998 to November 2013, and 866 eyes of 786 patients were included. The mean (SD) age was 70.7 (12.4) years with 62% women. Low levels of perioperative and postoperative complications were noted, and the visual outcomes at 2 weeks in this audit were significantly better than those of the CND, with 75.4% achieving a best-corrected vision of ≥6/6 and 87.3% ≥6/12, improving to 95.8% and 100%, respectively, for best-case analysis (p,0.001 for all comparisons). 99% achieved the same or a better postoperative visual acuity than preoperatively compared with 95% in the CND (p,0.001) and none lost two lines of Snellen acuity (versus 1.24%; p,0.001). Patients receiving one of the two designs of square-edged hydrophobic acrylic intraocular lenses used in this audit did not require later YAG laser treatment compared with 2.72% of those who had a polymethylmethacrylate intraocular lens (p,0.02). Biometry accuracy was within ±1.0 D of the predicted refraction in ...
From the posterior view (mp4 file).. Surgery for cataracts has undergone extensive evolution. Ancient knowledge viewed the cataratous eye as an imbalance of humors that needed displacement to recover vision. Using a needle, the surgeon would proceed to displace the abnormal humor until the crystalline lens dislocated. Modern cataract surgery has undergone significant changes and is now characterized by several steps: corneal incision, continuous curvilinear capsulorrhexis (CCC), hydrodissection, phacoemulsification, cortical aspiration, and intraocular lens (IOL) implantation.. Earlier surgical intervention to remove the entire cataractous lens required a 12 mm incision with subsequent suture closure. However, a small 2.4 to 2.8 mm wide clear corneal incision is enough to facilitate entry of the phaco handpiece while remaining sutureless for closure. The CCC technique was developed by Gimbel and Neuhann in the 1980s and truly revolutionized the phacoemulsification technique [16]. CCC involves ...

Results Six patients from out of 1056 undergoing cataract surgery (0.57%) were affected. Uveitis was the only identified risk factor for IOL dislocation, which occurred a mean 10.3 years following uncomplicated cataract surgery by phakoemulsification with endocapsular IOL implantation. The dislocation was in-the-bag in all six cases. Two patients presented with the IOL in the anterior chamber, and required removal of the IOL-bag complex, and are using aphakic refractive correction. Two patients with inferior IOL subluxation have been managed conservatively. Two patients underwent pars plana vitrectomy with sutureless scleral fixation of the existing IOL in one case, and IOL exchange with a scleral sutured IOL in the other. ...
Purpose: To compare surgically induced astigmatism (SIA) and refractive outcomes between two operation methods for late in-the-bag IOL dislocation. Methods: In this prospective, randomized, parallel-group clinical trial, 104 patients (eyes) were assigned to IOL repositioning by scleral suturing 1.5- to 2-mm posterior to limbus (n = 54) or IOL exchange with a retropupillar iris-claw IOL using a 5.5-mm scleral pocket incision (n = 50). The SIA was determined by vector analysis through conversion of corneal cylinders to Cartesian coordinates, and is presented as magnitude in diopters @ direction in degrees (D @ °). Follow-up was 6 months. Results: The SIA was 0.24 D @ 8° for IOL repositioning and 0.65 D @ 171° for IOL exchange, which was a nonsignificant group difference (X coordinate: P = 0.08; Y coordinate: P = 0.16). Mean SIA magnitude was 0.60 ± 0.50 D and 1.12 ± 0.85 D, respectively (P , 0.001). Mean postoperative spherical equivalent was −1.6 ± 1.6 D after IOL repositioning and −0.5 ...
Six third year ophthalmology residents incorporated the use of femtosecond cataract surgery during the beginning 3 months of their cataract surgical experience. The LenSx Femtosecond Cataract System (Alcon) was used to perform a 5 mm capsulotomy as well as the nuclear fragmentation during the initial 5 cases. This portion of the procedure was performed by the attending surgeon while the rest of the procedure was done by the resident. For every femtosecond performed capsulotomy the resident did 5 wet lab sessions demonstrating his ability to successfully complete a curvilinear capsulorrhexis lens removal on a pig eye. Visual outcomes, rate of complications such as anterior capsule rents, tears, inadequate size of capsulorrhexis, were compared to the previous years without the use of femtosecond technology ...

The common treatment for pediatric cataracts is to replace the cloudy lens with an artificial one. However, patients may suffer complications (severe lens proliferation into the visual axis and abnormal high intraocular pressure; SLPVA and AHIP) within 1 year after surgery and factors causing these complications are unknown. Apriori algorithm is employed to find association rules related to complications. We use random forest (RF) and Naïve Bayesian (NB) to predict the complications with datasets preprocessed by SMOTE (synthetic minority oversampling technique). Genetic feature selection is exploited to find real features related to complications. Average classification accuracies in three binary classification problems are over 75%. Second, the relationship between the classification performance and the number of random forest tree is studied. Results show except for gender and age at surgery (AS); other attributes are related to complications. Except for the secondary IOL placement, operation mode,
Yeah. We can use one of the choppers. Definitely. But theyre not as hard as a that, right? But theyre not as soft as pediatric cataract. So, I go with the mid-level instrument where it can help me to crack the nucleus as well as here what we require is just a little bit of a an edge. There are three ways to take it out. One, I a analyze the incision, and I can make into pieces. This doughnut, I can make into three quadrants. Or I can make it into one big quadrant and make - split it and take it as a nucleus. The third thing was the phaco. So, we use the phaco as one of the modalities here. I think that typical choppers are not really required in this kind of situation ...

Surgical. Cataract removal can be performed at any stage and no longer requires ripening of the lens. Surgery is usually outpatient and performed using local anesthesia. Approximately 90% of patients can achieve a corrected vision of 20/40 or better after surgery.. Several recent evaluations found that surgery can only meet expectations when there is significant functional impairment from poor vision prior to surgery. Visual function estimates such as VF-14 have been found to give more realistic estimates than visual acuity testing alone. In some developed countries a trend to overuse cataract surgery has been noted which may lead to disappointing results.. Phacoemulsification, typically comprises five steps, not including the anaesthetic.. Anaesthetic - The eye is numbed with either a subtenon injection around the eye or using simple eye drops.. Corneal Incision - Two cuts are made through the clear cornea to allow insertion of instruments into the eye.. Capsulorhexis - A needle or small pair ...

In that environment what are the obvious outcomes of future phone design? Firstly high quality media would require a big screen. Given the costs and the fact it had to fit in a persons pocket you are pretty limited on the best size and shape for a screen IE about the size of the iphones screen (the S3, which I use, is pushing it for the use size of a phone screen). Now given that you dont want to make the phone any bigger or any wider than you have to given people have to carry it around and hold it to their ear then reducing the space that isnt taken up by screen is a obvious must. The best way around this is touch screen interface which is much more efficient in its use of space. Now for the shape again you are trying to limit the form as much as you can, so you make it the shape of your screen and you round of the edges because THATS WHAT YOU DO WITH PHONES AND HAVE ALWAYS DONE WITH PHONES BECAUSE YOU DONT WANT TO POKE PEOPLE IN THE GOD DAMN LEG!

My first garden was, technically, not a garden at all. It was, in fact, a plot of stunted vegetables hiding their homely little selves within a sprawling weed patch.. Its amazing I wasnt arrested for the crime of "attempted gardening in the first degree.". About 40 years ago, early one spring when I was 21, I decided to dig up a big patch of lawn and grow vegetables. It was to be a dazzling garden of about 40 feet by 20 feet. There seemed to be plenty of sun on that back yard and so I started digging literally by hand, using just a sharp-edged shovel. It took many sweaty days to take off that layer of crab-grass disguised as "lawn." It took several more days to dig up the compacted soil.. I had never planted anything before, but I thought it would be a fun thing to do - to watch my vegetables grow and then share them with friends and neighbors. I scritched the soil with a rake, breaking up the lumps, but it seemed to be awfully dry and sandy. Then I watered it to make it nice and moist, ready ...

Her referring ophthalmologist came to observe her surgery, and she appreciated the moral support. Assuming the posterior sclera to be equally thin as the anterior sclera, I used topical anesthesia to avoid the risks of a retro- or peribulbar injection. I made the 2.6-mm clear corneal incision in the only place possible before encountering the first major problem. Despite lysing the posterior synechiae, inserting two iris retractors inferiorly, and maximizing the microscopes illumination and zoom, I simply could not get enough of a red reflex to see the anterior capsule (Figure 1). Capsular staining with trypan blue dye had not yet been described. The difficulty in puncturing her anterior capsule and the excessive mobility of her lens as I maneuvered the capsular flap indicated that her zonules were extremely loose. I had not expected this. After struggling along at a snails pace, I thought that I had successfully completed a capsulorhexis, but I could not be absolutely sure.. Following ...

A remotely operable ocular surgical cutting instrument (10), useful, for instance as a knife for a capsulotomy procedure, has a two portion main body (12) with one portion (16) oriented at an angle with respect to the other (14). A turning unit (20) extends through the main instrument body (12), and, to constitute a capsulotomy knife, a cutting blade (22) is mounted on the turning unit (20) at one end of the body (12). During operation, the orientation of cutting edge of the blade (22) with respect to the instrument body (12) is determined by manipulation of the opposite end of the turning unit at the other end of the instrument body (12).
Cataract surgery has undergone significant changes beginning with the abandonment of intracapsular surgery, and continuing with the advent of intraocular lenses, and continuing variations in extracapsular lens removal.

Very rare," admits Sereno, "that a plant-eater like Pegomastax would sport sharp-edged, enlarged canines" like that of a vampire. Some scientists have argued that consuming meat or at the least insects was a good part of the diet of heterodontosaurs, which evolved near the root of the great bird-hipped radiation of dinosaurs that includes the famous plant-eaters Triceratops and Stegosaurus.. Self-defense and competitive sparring for mates is more likely their role, argues Sereno in the study, based on microscopic examination of the teeth of Pegomastax and kin. Wear facets and chipped enamel suggest that the fangs of Pegomastax and other heterodontosaurs were used like those of living fanged deer for nipping or even digging rather than slicing flesh. A bizarre covering of bristles, something like that of a porcupine, likely covered most of the body of Pegomastax, which measured less than two-feet in length and weighed less than a housecat. These bristles first came to light in a similar-sized ...

Manual Small Incision Cataract Surgery also known as manual phaco or MSICS or SICS. This is the most cost effective cataract cataract extraction method with consistent very good visual outcome.We are demonstrating a real small incision 5.5 mm in this video. (You have seen a lot of SICS video at youtube but there incision size more than 8 mm). All types of cataracts (hard cataract,posterior polar cataract, mature cataract, hypermature cataract) can be operated by this method. Because we are breaking nucleus in the tunnel and taking out in the pieces. The breaking of the nucleus is done in the tunnel,so cornea is spared form the injury. Most of the cases having bright clear cornea and 20/30 or better vision on the first post operative day

Were observed two ...
Lens Implant. Traditionally, when a cataract develops, the eye lens is replaced with an artificial intraocular lens (IOL). The lens is usually focused for distance vision, requiring that the patient need to wear reading glasses or contact lenses to focus in on nearer objects..

|p|BACKGROUND: One of the challenges of hip arthroscopy is accomplishing a safe capsulotomy that allows efficient exposure of the central and peripheral compartments and at the end of the procedure permits secure closure. Two distinctly different capsulotomy approaches can be used to accomplish this task, the interportal capsulotomy (IPC) and the extracapsular capsulotomy (ECC). The IPC is a well-established commonly performed approach that carries some risk of iatrogenic injury to articular cartilage and labrum. The IPC for exposure of the central and peripheral compartments can be challenging, involves use of a 70 degree scope, and may be associated with prolonged traction times. The ECC approach utilizes a longitudinal capsulotomy along the long axis of the femoral neck offering a generous exposure of the hip joint with minimal risk of joint injury and greater surgical convenience in accomplishing the surgical tasks. The ECC approach uses a 30 degree scope and is essentially an arthroscopic version

A cut can vary in depth and seriousness but on most occasions still only penetrates the epidermis. As opposed to abrasions, cuts draw blood into the wound due to a problem caused to the circulatory system beneath the opening. Cuts may be caused by an accidental blow from a sharp-edged projectile (e.g. sticks or bats) or parts of specialised sports clothing such as football boot studs. Sustaining a cut should not impede sports participation except for the initial bandaging process. If the cut bleeds profusely and will not stop, to the extent that a bandage or plaster cannot contain it, then consult a medical professional as stitches may be necessary. Healing of cuts depends on severity, but from 1 to 2 weeks is a good indicator. Make sure that the area remains clean and that nothing remains lodged in there. Cuts often recover faster if exposed to the air, but bandaging guards against infection.. ...

Purpose: : The most common sight threatening complication of cataract surgery is posterior capsular rupture associated with vitreous presentation into the anterior chamber. The goals of anterior vitrectomy are to completely remove the vitreous in the anterior chamber while maintaining lens capsule integrity, minimizing retinal traction and the amount of vitreous removed. This study compares anterior vitrectomy via limbal versus pars plana approach in an induced posterior capsular rupture during phacoemulsification in cadaveric pig eyes. Methods: : Cataract extraction via phacoemsulsification was performed on five cadaveric pig eyes. A posterior capsular rupture was induced using a cystotome, and pressure was applied to fill the anterior chamber with vitreous. Indocyanine green (ICG) was injected to enhance vitreous visualization. A limbal anterior vitrectomy (LAV) was performed in 2 eyes and a pars plana anterior vitrectomy (PPAV) in 3 eyes. The length of time to completely remove the ICG ...

Practical design (particularly at high frequencies as in high speed digital logic circuits) requires that things like input and output impedance be taken into account. They determine things like device fanout (how many other gates can the output of one gate drive), the rise time of a change of logic level (hence switching delays), and whether to worry about signal reflections on the data paths between chips due to impedance matching issues. Circuit board traces act like transmission lines at high frequencies. Capacitance associated with inputs delays logic level transitions, rounding off square signal edges and introducing timing delays. The nice sharp-edged logic signals of a theoretical design can become quite a mushy mess and introduce unexpected race conditions or timing errors in what was a nice synchronous circuit design on paper ...

PURPOSE To evaluate whether cataract surgery in children should be performed with anterior vitrectomy and to examine the properties of the AcrySof SA30AL intraocular lens (IOL) in the pediatric eye. SETTING Filatov Institute, Odessa, Ukraine. METHODS Cataract surgery was performed in 66 children aged 3 to 15 years. They were randomized to surgery with or without anterior vitrectomy. All eyes were implanted with the single-piece AcrySof SA30AL IOL (Alcon). During the study, the patients who needed surgery for after-cataract had a second surgical procedure. Two years after surgery, the surgical method was evaluated using exact logistic regression. Also, the Evaluation of Posterior Capsule Opacification (EPCO) score was compared between the patients who had surgery for after-cataract and the patients who did not need this. The presence of posterior synechias and centration of the IOL were assessed. RESULTS Children in the younger age group (|/=62 months at surgery) had surgery for after-cataract more
A 59-year-old man with diabetes underwent uneventful phacoemulsification in 1990 in the left eye with implantation of a one-piece polymethylmethacrylate IOL. Open-angle glaucoma developed postoperatively and was treated with brimonidine (Alphagan, Allergan, Irvine, CA), timolol maleate (Timoptic, Merck & Co, West Point, PA), and latanoprost ophthalmic solution (Xalatan, Pfizer Inc., New York). The right eye had phthisis bulbi secondary to a surgery to repair a retinal detachment. The patient did not instill sufficient medication and the optic disc damage increased. In 2006, iris rubeosis with uveal ectropion developed secondary to diabetic retinopathy. Gonioscopy found new vessels in the angle with synechiae in 360° of the angle. The intraocular pressure (IOP) was 45 mmHg in the left eye. The best-corrected visual acuity (BCVA) was 1 logarithm of the minimum angle of resolution (logMAR) unit in the left eye. Two intravitreous injections of bevacizumab (Avastin, Genentech Inc., South San ...
0024]Typically the human lens capsule of the present invention may be supported on a solid substrate such as a plastics or glass surface, e.g. the surface of a petri dish. Sigma ligands may be first identified as such by conducting, for example, a radioligand binding assay, such as described in WO 00/00599 to ascertain that the test agent is a sigma ligand, before carrying out the method as described above. Importantly, sigma radioligand binding assays determine only that an agent binds to sigma sites and not whether it acts as an agonist or antagonist in functional terms (whether it acts to stimulate or inhibit the receptor). In WO 00/00599 it was disclosed that different sigma receptor subtypes--or even binding pockets on the same receptor molecule--can act in opposite ways to either promote or suppress apoptosis (cell death). Given that a number of sigma ligands bind to both sigma-1 and sigma-2 sites (that act in opposition to regulate cell death), the balance of their functional activities ...

Amar Agarwal is the pioneer of Phakonit which is Phako with a Needle Incision Technology. This technique became popularized as Bimanual phaco, Microincision cataract surgery (MICS) or Microphaco. He is the first to remove cataracts through a 0.7 mm tip with the technique called Microphakonit. He has also discovered No anesthesia cataract surgery and FAVIT a new technique to remove dropped nuclei. The air pump which was a simple idea of using an aquarium fish pump to increase the fluid into the eye in bimanual phaco and co-axial phaco has helped prevent surge. This built the basis of various techniques of forced infusion for small incision cataract surgery. He has also discovered a new refractive error called Aberropia. He has also been the first to do a combined surgery of microphakonit (700 micron cataract surgery) with a 25 gauge vitrectomy in the same patient thus having the smallest incisions possible for cataract and vitrectomy. He is also the first surgeon to implant a new mirror ...
Posterior capsule opacity (PCO) is the most common complication associated with cataract surgery. Fortunately, theres a relatively simple correction.
A cataract is a cloudy lens inside the eye and is located just behind the iris (color of the eye). The most common sign is a white or gray pupil. However, some cataracts are difficult to see without a complete eye exam.. Pediatric cataracts can be present at birth or develop later in childhood. They could be present in both eyes or only one eye. They can be inherited if there is a family history of childhood cataracts or can occur spontaneously. Some cataracts are caused by metabolic or genetic disorders and additional testing is required to identify problems elsewhere in the body.. As in adults, cataracts in children can limit vision. More importantly, cataracts in a child can lead to amblyopia, strabismus, and nystagmus (uncontrolled, rapid jerking movements of the eyes). While it is possible for a cataract to be so small that it does not affect vision, many childhood cataracts should be removed in a timely fashion to help prevent permanent vision loss.. ...
Automated capsulotomy is a new option that surgeons can choose for patients with opaque corneas, as well as when performing an open sky rhexis during the triple procedure and during surgery that requires the use of premium or multifocal lenses.

Once you have been checked-in, drops will be used to numb your eye; no injections or needles are used. When your eye is completely numb, an eyelid holder will be placed between your eyelids to keep you from blinking during the procedure.. Your ophthalmologist will use a YAG laser to create an opening in the center of the cloudy capsule. The opening allows clear passage of the light rays and eliminates the cloudiness that was interfering with your vision.. The entire procedure takes only about five minutes and you can leave soon afterward. The results of the procedure are almost immediate, however your vision will probably be a little blurry from the drops so someone will need to drive you home. Your doctor may prescribe anti-inflammatory drops for you to use for a few days following the procedure. Most patients resume their normal activities immediately.. ...

Posterior capsule opacification (PCO) is a fairly common complication of cataract surgery. Sometimes you can develop a thickening of the back (posterior) of the lens capsule which holds your artificial lens in place.This thickening of the capsule causes your vision to become cloudy. If this happens you may need to have laser treatment to make vision clear again. Once you have had the laser treatment for PCO it doesnt normally cause any long term problem with your sight.

The elbow joint is highly susceptible to joint contracture, and treating elbow contracture is a challenging clinical problem. Previously, we established an animal model to study elbow contracture that exhibited features similar to the human condition including persistent decreased range of motion (ROM) in flexion-extension and increased capsule thickness/adhesions. The objective of this study was to mechanically quantify pronation-supination in different injury models to determine if significant differences compared to control or contralateral persist long-term in our animal elbow contracture model. After surgically inducing soft tissue damage in the elbow, Injury I (anterior capsulotomy) and Injury II (anterior capsulotomy with lateral collateral ligament transection), limbs were immobilized for 6 weeks (immobilization (IM)). Animals were evaluated after the IM period or following an additional 6 weeks of free mobilization (FM). Total ROM for pronation-supination was significantly decreased ...
Cataract surgery is a very common procedure with low risks involved. Less than a single percent of patients will suffer from any serious complications that will necessitate further surgeries. If complications do arise, these are, more often than not, successfully treated through additional procedures.. While it is possible that your vision may get worse or that permanent damage may occur after the cataract surgery, these cases are extremely rare. Still, a comprehensive consultation with your eye doctor should be done so that you will be fully informed of all the possible risks.. Posterior Capsule Opacification. The most common risk that a cataract patient may encounter after surgery is the development of a condition called posterior capsule opacification, or PCO. In this condition, a portion of the capsule of your lens may thicken and lead to a cloudy vision. While some may mistake this as a sign of the cataract returning, it is actually cells growing at the back of the artificial lens.. This is ...
UNLABELLED: We describe a 40-year-old woman with von Hippel-Lindau syndrome, secondary chronic exudative retinal detachment, and white cataract with consequent leukocoria. Because the cataract was contracted and calcified, a black Morcher 85F poly(methyl methacrylate) IOL was implanted in the ciliary sulcus anterior to the lens to prevent posterior capsule rupture and potential destabilization of the retinal detachment with a risk for phthisis. Excellent centration of the black IOL was achieved with good cosmetic outcome and without postoperative uveitis or glaucoma. We suggest that this is a rare indication for implantation of an IOL designed for the sulcus but in the presence of the crystalline lens. This approach makes IOL removal, if necessary at a later date, relatively straightforward. FINANCIAL DISCLOSURE: No author has a financial or proprietary interest in any material or method mentioned.

The present invention relates to an intraocular lens, including a flexible capsule adapted to be inserted into the natural lens capsular bag. A polymerized portion is positioned within the flexible capsule, and an unpolymerized material is located within the flexible capsule, and has loose monomers and a polymerization initiator so that the unpolymerized material changes its volume when exposed to an energy source.
Clouding of the portion of the lens covering (capsule) that remains after surgery, often called aftercataract (posterior capsular opacification). This is usually not a big problem and can be treated with laser surgery, if needed. The type of IOL may affect how likely it is to have clouding after surgery ...
Posterior Capsule Opacity is NOT a result of a complication during or from your cataract surgery. It is however an unavoidable after effect of cataract surgery. It is easily treated and the vision in most cases is restored; as long as there is no other associated ophthalmic pathology.. The natural lens in the eye that forms a cloudy image known as a cataract sits inside what is called a capsule . The capsule is elastic in form and shrinks tightly around the lens. During cataract surgery the lens is removed through a small incision in the front of the lens capsule and vacuumed out and the new intraocular lens is put in its place. The capsule then wraps around it neatly, avoiding the need for sutures. Inside the lens are epithelial cells that continue to grow at a minute rate from the time our eyes form as a foetus. During cataract surgery these cells are removed with the cloudy lens, however it is unavoidable that some of the microscopic cells may remain. It is these epithelial cells that form ...

  • She carefully creates a small capsulorhexis and enlarges it slightly after the lens milk is removed. (eyetube.net)
  • Three trainees with minimal prior surgical experience underwent 3 consecutive trials using the Bioniko eyes and were evaluated by time and size of capsulorhexis, and for improvements in time between the first and third trials. (arvojournals.org)
  • Deep neural networks effectively model surgical technical skill in capsulorhexis given structured representation of intraoperative data such as optical flow fields extracted from video or crowdsourced tool localization information. (springer.com)
  • Using two capsulorhexis indices in this scale (commencement of flap and follow-through, formation and completion), we specified an expert performance when at least one of the indices was 5 and the other index was at least 4, and novice otherwise. (springer.com)
  • The Bioniko ophthalmic surgery model is a promising new tool which offers an alternative to an animal wet lab in order to assist trainees in learning the capsulorhexis. (arvojournals.org)
  • We separately modeled instrument trajectories and optical flow using temporal convolutional neural networks to predict a skill class (expert/novice) and score on each item for capsulorhexis in ICO-OSCAR:phaco. (springer.com)
