Profile of patients presenting for cataract surgery in the UK: national data collection. (1/410)

AIMS/METHODS: A national data collection exercise was carried out in more than 100 hospital eye service units within the UK to provide clinical and administrative information on patients undergoing cataract surgery. This included patient clinical data such as visual acuity at the time of wait listing and at the time of admission for surgery, presence of other eye disorders, other serious medical disorders, and data on waiting time and type of admission. RESULTS: The profiles of the 18 454 patients aged 50 years or older are reported. Findings of particular note were as follows. At the time of wait listing for cataract surgery 31% had visual acuity of 6/12 or better, 54% had visual acuity between 6/18 and 6/60, and 15% had less than 6/60 vision. Considering those who had visual acuity of 6/12 or better at the time of wait listing, by the time of admission for surgery, the vision deteriorated to 6/18-6/60 in 33% and in a further 3% the vision deteriorated to below 6/60. In patients with moderately poor visual acuity (<6/12-6/60) at the time of wait listing, 13% had less than 6/60 vision by the time of admission for surgery. CONCLUSION: This type of data collection and reporting exercise provides new material that can be used in the planning and provision of cataract surgery services in the UK.  (+info)

The triple procedure: in the bag placement versus ciliary sulcus placement of the intraocular lens. (2/410)

AIMS: To evaluate the influence of intraocular lens (IOL) placement on triple procedure clinical results and to investigate whether it is appropriate to use phacoemulsification in patients with large lens nucleus. METHODS: 40 consecutive penetrating keratoplasties combined with cataract extraction performed in a single institution were studied. Whenever possible a capsulorhexis was performed and the IOL was placed into the capsular bag. Phacoemulsification was used when the nucleus was too large to pass through the capsulorhexis. RESULTS: Out of 25 patients with an intact capsulorhexis phacoemulsification was used in 13 (52.0%) whereas the entire nucleus passed through the capsulorhexis in the remaining 12 patients (48%). The average 12 month visual acuity was 0.46 (SD 0.21) in patients with in the bag IOL (n = 23) and 0.29 (0.08) in patients with ciliary sulcus IOL (n = 13) (p = 0.04). Elevated intraocular pressure occurred in 26.1% (6/23) of patients with in the bag IOL and 61.5% (8/13) of patients with ciliary sulcus IOL (p = 0.08). The average postoperative graft thickness at 18 months was 552 (27) microns in the former group and 650 (29) microns in the latter group (p = 0.04). No significant difference in graft survival, postoperative endothelial cell density, astigmatism, and videokeratoscopic measurements was found between both groups. CONCLUSION: In the bag placement of the intraocular lens during the triple procedure results in better outcome of transplantation than ciliary sulcus placement of the IOL. Phacoemulsification allows removal of large nuclei through a 5 mm capsulorhexis without performing relaxing incisions out towards the periphery of the capsule.  (+info)

Visual outcome after phacoemulsification and IOL implantation in diabetic patients. (3/410)

AIMS: To follow visual acuity (VA) and progression of diabetic retinopathy (DR) after phacoemulsification in diabetic patients with different stages of DR and controls. METHODS: This prospective study included 27 diabetic patients with no or mild to moderate non-proliferative DR; 25 patients with moderate to severe non-proliferative, or proliferative DR; and 22 non-diabetic controls. All patients underwent uncomplicated, phacoemulsification surgery, with implantation of a heparin-surface modified (HSM) poly(methylmethacrylate) (PMMA) intraocular lens (IOL) into the capsular bag. Colour fundus photographs and fluorescein angiograms (FA) were taken at 1 week (baseline), 3 months, and 1 year postoperatively to determine stability or progression of DR. RESULTS: The VA of 46 diabetic eyes (88%), was improved 1 year after surgery and only six eyes (12%) were unchanged or worse. 41 diabetic eyes (79%) achieved a VA of 0.5 or better and 11 eyes (21%) had a final VA lower than 0.5. Significantly lower final corrected VA was found 1 year after surgery in eyes with advanced DR (median 0.5; range 0.1-1.0) compared with controls (1.0; 0.1-1.0) and eyes with no or mild to moderate DR (1.0; 0.1-1.0). Eyes with mild to moderate DR and clinically significant macular oedema (CSMO) 1 week postoperatively had a lower final VA than those without CSMO. Angiographic cystoid macular oedema (CMO) was detected with FA in 15% of all diabetic eyes 1 week postoperatively. 41 eyes (79%) showed no change or improvement of the retinal status 1 year after cataract surgery. Progression was found in 11 eyes (21%), mainly in eyes with mild to moderate DR and moderate to severe DR. Eyes with an indication for laser photocoagulation at baseline showed a significantly higher rate of progression of DR after surgery than those without indication for laser treatment. CONCLUSION: The final visual outcome was improved in the majority of diabetic eyes. Eyes with CSMO at the time of surgery had the worst prognosis regarding postoperative VA.  (+info)

Retained intravitreal lens fragments after phacoemulsification: a clinicopathological correlation. (4/410)

AIMS: To explore the relation between clinical course and timing of vitrectomy with the nature and intensity of intraocular inflammatory response in eyes with retained intravitreal lens fragments following complicated phacoemulsification. METHODS: Prospective evaluation of 22 eyes with retained lens fragments with emphasis on corneal clarity, uveitis, intraocular pressure (IOP), timing of vitrectomy, and visual outcome. Numbers of different types of inflammatory cells in vitreous washings were counted, masked to clinical details, in three non-overlapping adjacent high power fields. Relations between clinical and pathological findings were assessed. RESULTS: The IOP was raised in 19 eyes before vitrectomy and remained high in nine postoperatively. The latter had higher median total cell count (104 cells/mm(2)) than those with normal postoperative IOP (37 cells/mm(2)) but this difference was not statistically significantly different (p=0.17). Nine of 22 eyes underwent vitrectomy within 1 week of cataract surgery. Median total cell count in these eyes was 20 cells/mm(2) compared with 140 cells/mm(2) in eyes vitrectomised later-this difference was statistically significant (p <0.001). Final visual acuity was 6/12 or better in 13 eyes, these had fewer intravitreal inflammatory cells than the remaining six with poor visual outcome and no pre-existing cause for this (three patients excluded) (p=0.02). Macrophages were the predominant inflammatory cell type. CONCLUSION: There was significantly less inflammatory cell activity in eyes which had retained lens fragments removed early (within 1 week). Later removal was associated with persistently elevated IOP and poorer visual outcome.  (+info)

Visual experience during phacoemulsification cataract surgery under topical anaesthesia. (5/410)

BACKGROUND/AIMS: Visual awareness during phacoemulsification cataract surgery is an important determinant of patient satisfaction with any anaesthetic technique. Topical anaesthesia could be associated with significant visual awareness because it does not affect optic nerve function. METHODS: The visual experience during phacoemulsification cataract surgery under topical anaesthesia (without sedation) was assessed for 106 consecutive unselected patients. Patients were interviewed immediately after surgery using a standardised questionnaire that explored specific aspects of their visual experience. RESULTS: Four patients were excluded because they had poor recollection of their visual experience. The visual awareness of the remaining 102 patients comprised operating microscope light (99), colours (73), flashes of light (7), vague movements (19), surgical instruments or other objects (12), change in light brightness during surgery (49), change in colours during surgery (30), and transient visual alteration during corneal irrigation (25). No patient found their visual experience during surgery unpleasant, though the operating microscope light was uncomfortably bright for two patients. Six patients lost light perception for a short interval during surgery. There was no association between the various visual phenomena reported and patients' age, sex, preoperative visual acuity, cataract morphology, coexisting ocular pathology, or previous experience of cataract surgery under local anaesthesia (p>0.05). CONCLUSIONS: Patients experience a wide variety of visual sensations during phacoemulsification cataract surgery under topical anaesthesia. Topical anaesthesia does not, however, appear to result in greater visual awareness than regional anaesthesia. Preoperative patient counselling should include information about the visual experience during surgery.  (+info)

Pain relief with intracameral mepivacaine during phacoemulsification. (6/410)

AIM: To assess the efficacy and safety of an intraoperative intracameral injection of mepivacaine, administered when patients experienced pain during the course of cataract surgery under topical anaesthesia. METHODS: This is a prospective placebo controlled double masked randomised clinical trial. 50 eyes were included; 25 receiving the active compound and 25 receiving placebo. Mepivacaine (2%, 0.4 ml) or placebo was administered intraoperatively under the iris of the patients who experienced pain during the course of phacoemulsification in spite of previous topical anaesthesia. Efficacy was evaluated by the patients themselves using a five point subjective pain rating scale, the Keele verbal pain chart. Safety was measured by assessing intraocular inflammation (clinical evaluation and laser flare meter), intraocular pressure, and endothelial cell count. RESULTS: The pain rating score significantly diminished after intracameral injection in the mepivacaine group (mean 3.0 (95% CI 2.6-3.4) v 0.8 (0.3-1.3), p<10(-4))) while remaining unchanged in the placebo group (2.9 (2.6-3.2) v 2.9 (2.5-3. 3)), the mean reduction in pain score being significantly different between the two groups (p<10(-4)). There was no indication of increased postoperative ocular inflammation, intraocular pressure change, or endothelial cell loss. CONCLUSIONS: These results suggest that it may not be necessary to systematically add intracameral anaesthesia with topical anaesthesia for cataract surgery. An intraoperative intracameral injection, performed only in patients who happen to suffer during surgery, is safe and effective.  (+info)

Two clinical trials of an intraocular steroid delivery system for cataract surgery. (7/410)

PURPOSE: To determine the safety and efficacy of an intraocular dexamethasone drug delivery system (Surodex) in the treatment of inflammation following cataract surgery. METHODS: Surodex is a biodegradable polymer that releases dexamethasone for 7 to 10 days after placement in the anterior segment. Study 1 was a prospective, randomized, double-masked Phase II clinical trial of 90 cataract surgical patients that compared treatment with Surodex to treatment with a placebo drug delivery system and to no anti-inflammatory drug treatment at all. Study 2 was a separate prospective, randomized, double-masked study of 60 cataract surgical patients that compared treatment with Surodex to topical dexamethasone (eye drop) therapy. RESULTS: In the first study, Surodex was superior to placebo in suppressing postsurgical inflammation throughout the 60-day postoperative period, as judged by masked-evaluator, slit-lamp grading of cell and flare. The differences were statistically significant from postoperative day 3 through postoperative week 3. The majority of Surodex patients did not require topical steroid by 2 weeks after surgery (93%) or by 2 months after surgery (88%). In the second study, Kowa laser flare meter readings were lower in Surodex patients throughout the 90-day postoperative period. The results were statistically significant at 4, 8, and 15 days following surgery. There were no significant adverse complications of Surodex in either study. CONCLUSION: Surodex was safe and effective in suppressing postcataract surgery inflammation and appears to be a promising alternative to topical steroids.  (+info)

Visual outcomes after anterior vitrectomy: comparison of ECCE and phacoemulsification. (8/410)

PURPOSE: To determine whether vitrectomy instrumentation improved outcomes when vitreous loss occurred during either extracapsular cataract extraction (ECCE) or phacoemulsification (PE) with posterior chamber lens implantation (PCIOL). METHODS: A consecutive series of ECCE + PCIOL (group 1: 1985-1989) and PE + PCIOL (group 2: 1993-1997) surgeries by a single surgeon was reviewed retrospectively. RESULTS: In group 1, 14 of 647 patients (2.2%) and in group 2, 9 of 665 patients (1.4%) experienced vitreous loss. In group 1, final visual acuity averaged 20/83; in group 2, 20/25 (P = .005). Average follow-up was 5.7 years (group 1) and 3.2 years (group 2). Uveitis, glaucoma, corneal problems, and retinal problems were assessed. CONCLUSIONS: Anterior vitrectomy reduced complications from vitreous loss. Fewer vitreous losses occurred with PE than ECCE. Patients with vitreous loss after PE attained better vision.  (+info)

Demand is primarily generated by growing elderly population associated with high potential for ophthalmic surgeries. Longer life expectancy and growing shift towards an older average age has led to increased incidences of cataract driving the global ophthalmic viscosurgical devices market.
Cataract surgical techniques have significantly changed in recent years with the widespread adoption of smaller and smaller clear corneal incisions for phacoemulsification. Microincision surgery has many advantages, including reduced surgically induced astigmatism, faster visual recovery, and reduced intra and postoperative inflammation. In the recent times, microcoaxial phacoemulsification has gained popularity. The main advantage of this newer technique is that it uses the same methods as the conventional method but with smaller incisions. Curently, microcoaxial phacoemulsification is being performed through 1.8 as well as 2.2 mm incisions. However, there is still a debate as to which is the best absolute incision size for microcoaxial cataract surgery.. The aim of this study is to evaluate incision stability following microcoaxial phacoemulsification performed through 1.8 and 2.2 mm systems, as well as compare intraoperative performance and postoperative outcomes following microcoaxial ...
Purpose: : To compare the refractive outcomes of staged pars plana vitrectomy and phacoemulsification versus one-step combined phacoemulsification and vitrectomy. Methods: : Seventy-three patients underwent vitrectomy followed by phacoemulsification at a later date for various retinal disorders. Seventy-five patients underwent a one-step combined phacoemulsification with vitrectomy for similar retinal disorders. Ninety-six patients underwent phacoemulsification with lens implant (control group). A single surgeon operated on all patients using a standardised 20g self-sealing sclerostomy vitrectomy technique and clear corneal phacoemulsification with foldable acrylic IOL. Refractions were carried out three months post operatively. The spherical equivalent refractions (SER) aimed for at the time of the cataract surgeries were compared against those achieved post-operatively. The data collected in the two study groups were compared with a non-vitrectomised control group who had phacoemulsification ...

BACKGROUND: Cataract is the leading cause of blindness in the world, and clinically significant astigmatism may affect up to approximately 20% of people undergoing cataract surgery. Pre-existing astigmatism in people undergoing cataract surgery may be treated, among other techniques, by placing corneal incisions near the limbus (limbal relaxing incisions or LRIs) or by toric intraocular lens (IOLs) specially designed to reduce or treat the effect of corneal astigmatism on unaided visual acuity. OBJECTIVES: To assess the effects of toric IOLs compared with LRIs in the management of astigmatism during phacoemulsification cataract surgery. SEARCH METHODS: We searched CENTRAL (which contains the Cochrane Eyes and Vision Trials Register; 2019, Issue 9); Ovid MEDLINE; Ovid Embase and four other databases. The date of the search was 27 September 2019. SELECTION CRITERIA: We included randomised controlled trials (RCTs) comparing toric IOLs with LRIs during phacoemulsification cataract surgery. DATA ...
Cataract is a common ophthalmic disorder and the leading cause of blindness worldwide. While cataract is cured via surgical procedures, its impact on iris based biometric recognition has not been effectively studied. The key objective of this research is to assess the effect of cataract surgery on the iris texture pattern as a means of personal authentication. We prepare and release the IIITD Cataract Surgery Database (CaSD) captured from 132 cataract patients using three commercial iris sensors. A non-comparative non-randomized cohort study is performed on the iris texture patterns in CaSD and authentication performance is studied using three biometric recognition systems. Performance is lower when matching pre-operative images to post-operative images (74.69 ± 9.77%) as compared to matching pre-operative images to pre-operative images (93.42 ± 1.76%). 100% recognition performance is observed on a control-group of healthy irises from 68 subjects. Authentication performance improves if cataract

Phacoemulsification is a modern cataract surgery in which the eyes internal lens is emulsified with an ultrasonic handpiece and aspirated from the eye. Aspirated fluids are replaced with irrigation of balanced salt solution to maintain the anterior chamber. The term originated from phaco- (Greek phako-, comb. form of phakós, lentil; see lens) + emulsification. Proper anesthesia is essential for ocular surgery. Topical anesthesia is most commonly employed, typically by the instillation of a local anesthetic such as tetracaine or lidocaine. Alternatively, lidocaine and/or longer-acting bupivacaine anesthestic may be injected into the area surrounding (peribulbar block) or behind (retrobulbar block) the eye muscle cone to more fully immobilize the extraocular muscles and minimize pain sensation. A facial nerve block using lidocaine and bupivacaine may occasionally be performed to reduce lid squeezing. General anesthesia is recommended for children, traumatic eye injuries with cataract, for very ...

Results: Information on anatomical success was available for 4138 eyes of 4207 operations. Anatomical closure of MH was achieved in 85.7% (3546 eyes). Closure was higher in smaller MH (stages 1-2 versus stage 3: OR=0.35; stage 2 versus stage 4: OR=0.16, and in MH with shorter duration before the operation (OR=0.94). Macular Holes were more likely to close when dyes were used to facilitate internal limiting membrane (ILM) peeling (odds ratio=1.73 to 3.58). The most important predictors of postoperative BCVA were the preoperative BCVA (estimate=0.39, p,0.001) and closure of the macular hole (estimate=0.34, p,0.001). We observed Larger improvement in BCVA in combined vitrectomy and phacoemulsification (estimate = 0.10) and post cataract surgery in phakic eyes (estimate=0.05). Retinal tears occurred in 5.1% of eyes, and were less with use of trocars (OR= -1.246) and in combined vitrectomy/ phacoemulsification surgery (OR= -0.688 ...

Cataract surgery in patients with pseudoexfoliation syndrome: current updates Luigi Fontana, Marco Coassin, Alfonso Iovieno, Antonio Moramarco, Luca Cimino Ophthalmology Unit, Arcispedale Santa Maria Nuova – IRCCS, Reggio Emilia, Italy Abstract: Pseudoexfoliation is a ubiquitous syndrome of multifactorial origin affecting elderly people by increasing the risk of cataract and secondary glaucoma development. Despite modern techniques and technologies for cataract surgery, pseudoexfoliation syndrome represents a challenge for surgeons because of the increased weakness of the zonular apparatus and limited pupil dilation. Due to the inherent difficulties during surgery, the risk of vitreous loss in these patients is several times higher than in cataract patients without pseudoexfoliation. Using currently available surgical devices (ophthalmic viscosurgical device, iris retractors and ring dilators, capsular tension ring, etc.), the risk of intraoperative complications may be much reduced, allowing

To establish benchmark standards for refractive outcome after cataract surgery in the National Health Service when implementing the 2004 biometry guidelines of the Royal College of Ophthalmologists and customising Aconstants. Three cycles of prospective data were collected throughout the cataract care pathway on all patients using an electronic medical record system (Medisoft Ophthalmology), between January 2003 and February 2006. The electronic medical record automatically recommends the formula to be used according to the College guidelines and allows Aconstants to be customised separately for either ultrasound or partial coherence interferometry methods of axial length measurement and for different intraocular lens models. Consultants and trainees performed routine phacoemulsification cataract surgery and new intraocular lens models were introduced during the cycles. Uncomplicated cases within-the-bag fixation, achieving 6/12 Snellen acuity or better were included. Community ophthalmic opticians
Deep brain stimulation provides benefits for people with Parkinson disease by managing some of their complications. None of the few reports in the current literature establishes the functionality of deep brain stimulation when activated during phacoemulsification.A 70-year-old woman with subthalamic deep brain stimulator (DBS) for advanced Parkinson disease was referred to our center for cataract surgery. To evaluate any possible interference between ultrasounds and the DBS, we registered the impedance of the electrodes before and after surgery.The patient underwent uneventful phacoemulsification of her right eye under topical anesthesia with her internal pulse generator device activated. During the surgical procedure, all potential variations of the impedance of the electrodes were recorded.This report demonstrates that phacoemulsification under topical anesthesia is a feasible procedure in patients with DBS, showing no interference between the ultrasounds and the internal pulse ...
There are two main types of cataract surgery procedures: phacoemulsification and laser.. Phacoemulsification involves using ultrasound waves to break up the formed cataract. The cataract pieces are then gently suctioned out of the lens capsule. A new, artificial lens, one that is clear, is inserted and positioned precisely where the cloudy lens used to be.. Advances in technology have provided other options other than the mono-focal lens used previously in phacoemulsification procedures. An inserted Toric lens can also correct distance vision while a multi-focal inter-ocular lens (IOL) corrects both near- and far-sightedness.. Laser technology, the exact technology used in Lasik surgeries, can also be used to remove cataracts. This technology, known as femtosecond laser technology, uses an accurate, predictable and safe laser to make the corneal incision, gain access to the cataract through the lens capsule, and break up the cataract tissue for easy removal. Using a laser also makes it less ...

PURPOSE: To report the impact of posture-related ocular cyclotorsion on one surgeons surgically induced astigmatism (SIA) results and the variance in SIA. SETTING: Institute of Eye Surgery, Whitfield Clinic, Waterford, Ireland. METHODS: This prospective randomized controlled study included eyes that had phacoemulsification with intraocular lens implantation. Eyes were randomly assigned to have (intervention group) or not have (control group) correction for posture-related ocular cyclotorsion. In the intervention group, the clear corneal incision was placed precisely at the 120-degree meridian with instruments designed to correct posture-related ocular cyclotorsion. In the control group, the surgeon endeavored to place the incision at the 120-degree meridian, but without markings. RESULTS: The intervention group comprised 41 eyes and the control group, 61 eyes. The mean absolute SIA was 0.74 diopters (D) in the intervention group and 0.78 D in the control group; the difference between groups was ...
The reduction in ocular surface temperature toward the end of post-cataract surgery follow-up may be associated with increased instability of the tear film after phacoemulsification. Therefore, patient awareness regarding the possibility of clinical symptoms of dry eye syndrome during the first month after surgery should be part of clinical management of cataract surgery. Ocular surface temperature did not increase after cataract surgery, suggesting the absence of significant inflammation, and the temperature about 1 month after cataract surgery was comparable to that before surgery. Nevertheless, the negative correlation between age and ocular surface temperature should be of concern in the elderly ...
IMPORTANCE: The effectiveness of intraocular pressure (IOP) lowering phacoemulsification combined with goniosynechialysis (GSL) compared with phacoemulsification without GSL remains unknown. OBJECTIVE: To compare the IOP outcome after 1 year in patients with synechial primary angle-closure disease (PACD) and cataract who underwent phacoemulsification with intraocular lens implantation (PEI) alone compared with PEI with GSL (PEI-GSL). DESIGN, SETTING, AND PARTICIPANTS: A multicenter randomized clinical trial was conducted from September 29, 2011, to March 16, 2015; data analysis was performed from April 1, 2015, to March 4, 2019. Patients with PACD, defined as primary angle closure or primary angle-closure glaucoma, and at least 90° peripheral anterior synechiae (PAS) with cataract were included. Patients were randomized to undergo PEI alone or PEI-GSL. Patients were followed up for 1 year with standardized evaluations. Intention-to-treat analysis was performed. INTERVENTIONS: ...
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 ...

Cataracts are classically defined as an opacity within the lens, directly obscuring visualization of the fundus. There is currently no approved medical therapy for management of cataracts in dogs. Surgical correction has historically been performed as an intracapsular procedure, but phacoemulsification, an extracapsular extraction, is now the preferred method of surgical correction. Breeds predisposed to development of both cataracts and lens-induced uveitis warrant special consideration, as delay in phacoemulsification may result in chronic lens-induced uveitis and severe visual impairment post-operatively. Success rates of phacoemulsification within 6 months postoperatively drop from 95% with no pre-existing lens-induced uveitis to 52% if the condition exists before surgical correction. Owners with dogs with congenital or juvenile cataracts should be counseled about the possibility of development of this condition, and its potentially devastating consequences for future visual acuity ...
Because the crystalline lens can contribute to the development of PCACG, lensectomy remains a viable option for some eyes. The exact mechanism by which cataract surgery lowers IOP in glaucomatous eyes remains unknown. Evidence suggests that in eyes with narrow and closed angles, the level of IOP lowering after cataract surgery is proportional to the resultant widening of the angle.17 Phacoemulsification and intraocular lens implantation can lower IOP, reduce or remove the critical anatomical characteristics that produce pupillary block, and subsequently increase angle width.17 Research shows, in eyes with PCACG and co-existing cataract, that phacoemulsification alone can significantly reduce both IOP and the need for topical therapy, supporting cataract removal as a primary treatment rather than LPI and stepped-medical therapy.18,19 The role of clear lensectomy (i.e., extraction of the non-cataractous lens) in patients with PCACG is unclear. The Effectiveness in Angle Closure Glaucoma of Lens ...
The cataract removal and iStent procedure is usually performed under local anesthesia. Your surgeon will first perform the phacoemulsification procedure to remove the cataract. With an ultrasonic device, the cloudy lens is broken up and removed and an artificial intraocular lens (IOL) is inserted. Using the same incision, the titanium iStent will be inserted by a preloaded, single-use, sterile applicator. Your surgeon will slowly advance the iStent into the trabecular meshwork of your eye and push the button on the inserter to release the iStent. The cataract removal and iStent implant only take about 15 to 20 minutes per eye.. After the Surgery. iStent is an outpatient procedure, and you can go home the same day. After the surgery, your eye may be covered by an eye shield that you can remove the following morning. You will receive antibiotic and anti-inflammatory eye drops to use for the next four to six weeks. Most likely, you will see your ophthalmologist the following day.. Recovery time is ...

This surgery has continued to evolve over the past several years, often leading the way for our medical colleagues. Years ago ophthalmologists were the first to utilize microsurgery techniques. The microscope came into use for the cataract surgery nearly 20 years ago. Ophthalmologists also pioneered the use of lasers for surgery.. Cataract surgery has continued to require a smaller and smaller incision over the years. About 10 years ago, the average cataract incision was nearly 11 or 12 millimeters. Now with phacoemulsification, the cataract is removed with a vibrating handpiece. This requires an incision no more than 3 millimeters (1/8 inch).. Flexible lens implants can be folded in half and can be passed through an incision nearly as small as the phacoemulsification needle itself. As the incision has shrunken, the need for sutures has diminished. In the great majority of cataract surgeries, no sutures are required.. The advantages of this new small incision surgery are quite significant. ...

Preoperative Complications Spontaneous Lens Capsule Rupture Occurs in cataracts associated with canine diabetes mellitus. Affected dogs have often been diabetic for only a few months with the onset of cataract on average only a month previously. The rupture occurs most often at the equator and is the result of rapid intumescence. Uveitis and intra-lenticular uveal pigment are common. Lens-Induced Uveitis. While surgeon opinion differs on pre-operative treatment and when to operate these patients, personally I have less respect for this preoperative change than in past. With new preoperative systemic NSAIDs, phacoemulsification, viscoelastic agents I often treat these eyes for 24-48 hours prior to surgery and then operate..

Dr. Agarwal is the pioneer of phakonit, which is phacoemulsification with needle incision technology. This technique became popularly known as bimanual phaco, microincision cataract surgery, or microphaco. Dr. Agarwal was the first to remove cataracts through a 0.7-mm tip with the microphakonit technique. He also discovered no anesthesia cataract surgery and FAVIT (fallen vitreous), a new technique to remove dropped nuclei. Using an aquar-ium fish pump to increase the fluid into the eye in bimanual phaco and coaxial phaco has helped prevent surge. This formed the basis of vari-ous techniques of forced infusion for small--incision cataract surgery. Dr. Agarwal also discovered a new refractive error called aberropia. He was the first to perform a combined surgery of microphakonit (700--μm cataract surgery) with a 25--gauge vitrectomy in the same patient, thus creating the smallest incisions pos-si-ble for cataract and vitrectomy. He was the first surgeon to implant a new mirror telescopic ...

The keratome should be fully advanced into the anterior chamber, so that the incision width is uniform along its length. This ensures that the manoeuvrability of the phaco tip and hand piece is not restricted by the internal aspect of the incision. It also reduces the risk of compression of the irrigation sleeve or iatrogenic detachment of Descemets membrane when introducing the phaco tip into the anterior chamber. The choice of keratome width is determined by that recommended ...

DR DOWNING: Okay. Good morning! Happy you could join us this morning. I want to talk a little bit about the need for learning different kinds of techniques for phacoemulsification. Now, as you begin doing it, you will find a technique that works for you most of the time, and thats what youll use most of the time. But there are special circumstances where you need to learn to do cataracts in different ways to avoid different problems. Divide and conquer is a technique thats very old, but still works very well. And its still the favorite technique for many experienced phaco surgeons. Its usually safe, its relatively easy to learn, and its a good fallback if youre having a problem with another technique, often. To do divide and conquer, you make four deep grooves in the cataract, in a cross shape. Then you separate these into quadrants and emulsify each quadrant. You can handle them usually pretty easily that way, and rotate them. And this is an example of a divide and conquer technique. I ...
In this video, Steve Dewey, MD, demonstrates FUSION® Phaco Technology with a dense cataract using the WHITESTAR Signature® System. FUSION® Phaco Technology allows the surgeon to switch between Peristaltic and Venturi pumps without halting the case. Also, combining with Ellips® FX ultrasound, which is simultaneous blend of longitudinal and transversal movement that yields a more effective cutting effect thats designed to reduce phaco time. According to Dr. Dewey, Venturi vacuum, because it does not rely on occlusion, is more efficient, and thus may be a better choice for cataract removal.
This case study presents the results and advantages of phacoemulsification, which Dr Dieter W Klass and his team applied after previous implantation of an iris-fixated phakic IOL (pIOL) (Artisan, Ophtec) for the correction of high myopia without explantation of the pIOL.

A method and apparatus for precisely controlling particle movement relative to a phacoemulsification needle tip is provided. The design monitors actual vacuum present and calculates a pulse shape amplitude waveform proportional to the amount of measured vacuum. An increase in vacuum indicates that the handpiece/needle is becoming occluded by a large particle. The present design determines whether additional power is required to bump or move a large particle away from the needle tip. The present design may employ a control loop that senses and continuously monitors vacuum. The design may dynamically vary the amount of ultrasonic energy delivered to the surgical area in response to the observed actual vacuum, and can actively vary the amount of power delivered to the surgical area based on the size of the particle and the resultant vacuum realized.
