Only one previous study has systematically investigated the visual experience of patients during cataract surgery.12This study assessed the visual experience of 56 patients during extracapsular cataract surgery under regional anaesthesia (peribulbar and retrobulbar blocks). Visual awareness was absent or limited to only light perception for four patients. The remaining patients observed colours (80%), movements (68%), flashes (66%), abstract colour images (55%), and objects (20%). During the course of surgery, patients also observed a change in light brightness (64%) and colours (20%).. Limited aspects of the visual experience during extracapsular cataract surgery under regional anaesthesia have also been reported in two other studies. In one study, surgical instruments were observed by 73% of patients during surgery under retrobulbar anaesthesia.13In another study, no patients observed surgical instruments during surgery under peribulbar anaesthesia but 20% of patients perceived abstract visual ...

Purpose: To determine when the mean central corneal thickness (CCT) returns to normal values after uneventful phacoemulsification. Material and Methods: This was a prospective case series. The study was carried out at the Section of Ophthalmology, Department of Surgery, Aga Khan University Hospital, Karachi. Eyes scheduled to undergo phacoemulsification during December 2011 - March 2012 were eligible to be included. Eyes with corneal degenerations, dystrophies or high pre-op astigmatism were excluded. A structured proforma was used to collect data on sociodemographics, comorbids, visual acuity, and CCT before surgery and 1 day, 1 week and 1 month after surgery. Changes in the mean CCT over time were measured using repeated measures Analysis of Variance (ANOVA) was done. Results: Eighty one eyes were included in the study. The mean (±SD) age of the participants was 58.30 (± 10.04) years. The majority of them (58.0%) were women. Sixty two (76.5%) eyes completed the last follow-up and were included in

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 ...

This study suggests an association between the use of three piece silicone polypropylene intraocular lenses and an increased risk of postoperative endophthalmitis following uncomplicated phacoemulsification.. The authors acknowledge the limitations of this retrospective study. There was no significant difference in mean age or sex distribution between the patients in the two IOL groups but other possible confounding elements cannot be completely excluded. We were not able to investigate the influence of possible confounding variables using multivariate analysis because the number of cases with endophthalmitis was small. Patient allocation to IOL type was unrandomised and consequent selection bias may have contributed to the observed association. Although the procedures were performed by different surgeons with unstandardised operative technique and differing prophylactic antimicrobial regimens, the surgical protocol did not change otherwise during the study period and we could identify no ...

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 ...

In this video, Dr. Rushad Shroff and colleagues from India detail their approach for performing phacoemulsification in patients with corneal opacities.

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 ...

Despite a series of challenges and risks, phacoemulsification with IOL implantation proved safe in eyes with microphthalmos and nanophthalmos, according to a study.The retrospective analysis included 103 eyes with axial length less than 21 mm that underwent phacoemulsification and IOL implantation. The median follow-up interval was 6.3 months. Full Story →. ...

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.. Intraoperative Complications Intraoperative Miosis. A rare occurrence with current methods of presurgical patient preparation and cataract extraction.

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.

AIM: To evaluate the clinical utility of automated refraction (AR) and keratometry (KR) compared with subjective or manifest refraction (MR) after cataract or refractive lens exchange surgery with implantation of Lentis Mplus X (Oculentis GmbH) refractive multifocal intraocular lens (IOL). METHODS: Eighty-six eyes implanted with the Lentis Mplus X multifocal IOL were included. MR was performed in all patients followed by three consecutive AR measurements using the Topcon KR-8000 autorefractor. Assessment of repeatability of consecutive AR before and after dilation with phenylephrine 10%, and comparison of the AR and KR with MR using vector analysis were performed at 3mo follow-up. RESULTS: Analysis showed excellent repeatability of the AR measurements. Linear regression of AR versus MR showed good correlation for sphere and spherical equivalent, whereas the correlation for astigmatism was low. The mean difference AR-MR was -1.28 0.29 diopters (D) for sphere. Astigmatism showed better correlation

Background Cataract and glaucoma are both common comorbidities among older patients. Combining glaucoma surgery with minimal invasive phacoemulsification (phaco) is a considerable option to treat both conditions at the same time, although the combination with filtration surgery can produce a strong inflammatory response. Combined non-penetrating procedures like canaloplasty have shown to reduce intraocular pressure (IOP) comparable to trabeculectomy without the risk of serious bleb-related complications. The purpose of this retrospective study was to compare the outcomes of phacotrabeculectomy and phacocanaloplasty. Methods Thirty-nine eyes with concomitant cataract and glaucoma who underwent phacotrabeculectomy (n = 20; 51.3%) or phacocanaloplasty (n = 19; 48.7%) were included into this trial on reduction of IOP, use of medication, success rate, incidence of complications and postsurgical interventions. Complete success was defined as IOP reduction by 30% or more and to 21 mmHg or less

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 ...

Fuchs endothelial dystrophy is a progressive, bilateral disease of the corneal endothelium, which eventually leads to corneal decompensation. In the early stage, some patients develop visually significant cataract. During cataract surgery ultrasound (US) power is used to emulsify the lens, which leads to endothelial cell loss and tissue damage. The reduction of US power has become the primary surgical goal in cataract surgery, which is especially important in patients with Fuchs endothelial dystrophy to limit endothelial cell loss.. In 2006, Alcon Surgical introduced a torsional mode in its phacoemulsification system (Infiniti Vision System). It includes a handpiece that produces rotary oscillations of the phacoemulsification tip and is suggested to reduce the amount of US power required to remove the cataractous nucleus, because it does not produce repulsion and breaks up the cataract by shearing and not by the conventional jackhammer effect. This reduction in US power, could lead to less ...

Purpose: To evaluate corneal endothelial cell loss after phaco with ExPress implant compared to phaco trabeculectomy. Methods: Forty eyes of forty patients affected by cataract and open angle glaucoma were randomized to Micro incision cataract surgery (MICS) phaco with Express P50 implant under scleral flap (group 1) or MICS safe-phacotrabeculectomy (group 2) after informed consent. All patients were operated by two-site surgery. There were no statistically significant differences in age, sex, anterior chamber depth and axial length. Non contact corneal specular microscopy (Tomey 3000 tm) was performed in all eyes before and 1st, 3rd , 6th months after surgery. Endothelial cell density (CCD), coefficient of variation in cell size (CV) and percentage of hexagram cells (HEX) between the two groups were considered before and after surgery. Mean endothelial cell count was measured in the central corneal area and in the superior area close to Express implant and close to trabeculectomy site. One-way ...

DR BENJAMIN: So this is a young man with a mature cataract. We dont know why. Hes not atopic. And as far as we know, hes never had steroids. So, you have to be a bit careful not to go too wide with the capsulorrhexis. So, I tend to try and spiral it outwards like this. Its going very slowly. And then every now and then you have to pull it backwards, just to get the trajectory right.. His mother noticed this, she says, a couple of weeks ago. My guess is its been there for a lot longer, because its quite a dense, white cataract. So, with these pediatric cataracts, the capsule is much more elastic than usual. And the VisionBlue helps to stiffen it up a little bit.. And the hydrodissection, please.. And then I use the phaco probe. Some people just aspirate pediatric cataracts, but sometimes theyre much harder than they look. And I tend to use the phaco probe, because its a very good aspirator, and if I need any phaco power, then its there.. Okay. So, well just try the IA now, please. Are ...

Cataract removal is one of the most common operations performed in the United States. It also is one of the safest and most effective types of surgery. In about 90 percent of cases, people who have cataract surgery have better vision afterward.. Cataract Surgery/ Laser Cataract Surgery (Phaco/ Femtosecond Laser) are achieved by the removal of the natural lens and the placement of an implant that best fits your personal needs. There are two technologies to choose from when performing this task. There is the most common practice of phacoemulsification wherein the internal lens is emulsified with an ultrasonic handpiece and aspirated from the eye and there is also an advanced bladeless technology wherein a laser is utilized to cut the lens into small pieces prior to being aspirated from the eye. Please ask your surgeon during your consultation which method would be best for you.. More information can be found at www.reclaimyourvision.com/cataract/cataract-surgery-options.shtml.

It allows the emulsified cataract to be removed through a narrow incision of 2 to 3 mm. The wounds are self-healing, so stitches are not required. This allows the patients eyes to recover and heal ...

A concise review and comprehensive guide to improving cataract surgery outcomes. Significant advances have been made in refractive surgery in the last decade. Eye surgeons today can leverage many cutting-edge intraocular lens (IOL) technologies such as multifocal, extended depth of field, toric, accommodating, and aspheric. Concurrent innovations including optics, phacoemulsification, superior keratometry and biometry, and posterior cornea evaluation have resulted in improved cataract surgery outcomes. Recent advances in the diagnosis and treatment of cataracts have dramatically improved patient satisfaction following cataract surgery, yet common and rare complications still occur such as dry eye, endophthalmitis, and retinal detachment. Furthermore, only 80% of cataract surgery procedures bring patients to within 0.5 diopters of their needed refraction.. Optimizing Suboptimal Results Following Cataract Surgery: Refractive and Non-Refractive Management presents the latest techniques for ...

This type of laser vision correction does not require any corneal incision at all. A mild alcohol solution is placed on the corneal to loosen the top layer of tissue. Only the most superficial layer of the cornea is gently brushed aside. This thin flap is then replaced after the laser reshaping is complete. Less tissue is removed than with traditional Lasik. Patients with thin corneas, or patients who have had previous vision correction such as RK, can possibly now have laser vision correction safely performed. Healing may be faster than with traditional PRK ...

Opening the capsule to reach the cataractInserting the Implant Cataract surgery is among the most frequently performed and safest surgical procedures in all of medicine. Cataract surgery is usually performed under local anesthesia on an outpatient basis. You come into the operating room, have the surgery done, and go home on the same day. Your surgeon will send you home with a protective shield covering your eye. Since you are awake for the surgery you may hear your doctor and the other people assisting at surgery talking while you are in the operating room. This is a very normal part of the experience.. Cataract surgery is usually performed using a procedure called phacoemulsification. A very thin instrument is inserted into the eye either through the sclera or white part of the eye or the cornea or window to the eye. This instrument breaks apart the cataract using high frequency ultrasounds. Once the cataract is emulsified it is removed using the same instrument. This allows your SkyVision ...

A few months after we switched from cohesive to adhesive OVDs, which was newly added to our clinic, during cataract surgery, we observed that more patients complained of floaters after cataract surgery. Because the cataract surgeries were uneventful and nothing changed but newly added OVDs, we suspected new OVDs for these symptoms. Previous reports demonstrated that OVDs with higher molecular weight or sodium hyaluronate concentration might induce increased IOP and this changes in IOP stressed on PC-AMH barrier and could disrupt it [10,11]. We presumed that the IOP spike during surgery with the new OVDs was responsible for these symptoms, so we attempted to remove some OVDs during hydrodissection, since this surgical steps is the point at which the IOP is the highest. Since we checked postoperative floater symptoms routinely, we have compared the symptoms of floaters before and after the change of OVDs. PC-AHM barrier is thought to act as a mechanical barrier separating the physical and ...

MEDICAL ANIMATION TRANSCRIPT: If you have blurred vision or other complications due to a cataract in the lens of your eye, your doctor may recommend surgery to remove the cataract. The lens is a clear disk that receives light through the pupil, and focuses it on the retina to help produce a clear image. The lens is mainly composed of water and proteins. As you age, these proteins may begin to clump together and cloud the lens. This clouding is called a cataract. A cataract can block light from entering your eye, and cause blurry vision. Before your procedure, you will be given eye drops to dilate your pupil, and the area around your eye will be washed. In most cases, you will be given an injection of local anesthetic around or behind your eye. You may also be offered a sedative to help you relax. Most cataract surgeries last less than an hour. The most common method for removing cataracts is phacoemulsification. In this procedure, your surgeon will look through an operating microscope, and make a tiny

A cataract is a clouding of the crystalline lens of the eye, which may occur slowly or rapidly. Symptoms that occur with cataracts include decreased near or distance vision and glare or halos.. Todays cataract surgery utilizes a small incision, no-suture technique. No shots or needles are used behind the eye. The cataract lens is removed with an instrument that uses high energy ultrasound. It is called phacoemulsification. This instrument breaks the cataract up into very small particles, which are then aspirated from the eye.. Following the removal of the cataract, an intraocular lens is placed in the eye through the small incision to take the place of the cataract lens.. Antibiotic drops and steroid or nonsteroidal drops are used in the eye postoperatively. You will be seen on postoperative day one to evaluate the eye. As with any surgery, complications can occur, and there is a possibility of hemorrhage or infection.. After cataract surgery the cataract does not return. However, one out of ...

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..
