Background: At present, the only effective treatment of posterior capsular opacification (PCO), which is the most common complication of modern cataract surgery, is Neodymium-Yttrium Aluminum Garnet (Nd:YAG) laser capsulotomy. There are few complications associated with this easy and quick laser capsulotomy. The current study was conducted in a tertiary hospital of Odisha with an objective to find the safety and efficacy of Nd:YAG laser capsulotomy in the management of defective vision due to posterior capsular opacity.Methods: The study was conducted among the patients attending the Ophthalmology out patient department of a tertiary hospital in Odisha with defective vision due to posterior capsular opacity after cataract surgery. Nd:YAG laser capsulotomy was carried out in all patients with significant PCO. Visual acuity and intraocular pressure were recorded before and after the procedure. The cases were carefully followed up and looked for any complication and visual acuity was assessed during follow up visits.Results: In the study 184 participants were included. Visual improvement was observed in 97.8% participants. Visual acuity improved to 6/6 in 21.73 %, 6/9 in 36.41 % cases, 6/12 in 15.21 % cases. Raised IOP was recorded among 46% of participant after 4 hrs of laser capsulotomy which was later observed among 12% of participants on follow up visit at 1 week. The most common complication recorded was transient rise of IOP (46.3%) followed by aqueous flare (28.8%).Conclusions: Nd:YAG laser capsulotomy is a noninvasive, effective, relatively safe procedure for PCO with good visual outcome.

BACKGROUND Posterior capsule opacification (PCO) is the most common delayed complication of cataract surgery. Nd:YAG (Neodymium yttrium aluminium garnet) laser posterior capsulotomy presents the advantages of a non-invasive, effective, relatively safe technique to manage intact posterior capsule that opacifies postoperatively. With this background we want to study the visual outcome and complications following Nd-YAG laser posterior capsulotomy in posterior capsular opacification following small incision cataract surgery (SICS). METHODS The study includes 64 patients attending outpatient department of a tertiary eye care hospital at Latur from June 2018 to May 2019 who have undergone SICS with PMMA PC IOL (polymethyl methacrylate posterior chamber intraocular lens) implantation and clinically diagnosed with posterior capsular opacification. 64 eyes with PCO were subjected to Nd:YAG laser posterior capsulotomy after detailed slit lamp bio microscopic examination pre- and post-capsulotomy. Follow-up was done at 1 hour, 1 week, 2 weeks and 4 weeks and patients were examined for visual outcome and any complications at each visit. RESULTS There were 16 males (25 %) and 48 females (75 %) with a mean age of 65 years. Posterior capsule opacification occurs within 3 years accounting for 46.9 % of the cases. Elschnig pearls type of PCO was more common when compared to fibrous type of PCO. Best corrected visual acuity (BCVA) before Nd:YAG laser capsulotomy was less than 6 / 60 in 35 patients (54.7 %) and within 6 / 60 to 6 / 24 in 23 patients (35. 9 %) with 6 patients (9.4 %) accounting for visual acuity between 6 / 24 to 6 / 18. After Nd - YAG Laser Capsulotomy, 46.9 % gained best corrected visual acuity of 6 / 18 or better, 39.1 % cases improved 6 / 12 and better and BCVA of 6 / 9, 6 / 6 was observed in 11 cases and 1 case respectively. Only 12 out of 64 patients had complications. Raised intraocular pressure (IOP) was found in 4 patients. Intraocular lens (IOL) pitting was found in 8 patients. CONCLUSIONS Nd:YAG laser capsulotomy is a safe, effective and a non-invasive procedure which avoids all the complications of surgical capsulotomy in patients of posterior capsule opacification.

<strong>Aims:</strong> To study the visual outcome following Nd:YAG laser posterior capsulotomy and to study the complications associated with Nd:YAG laser posterior capsulotomy. <strong>Material and Methods:</strong> The study included a total of 100 eyes of 100 patients who fulfilled the inclusion and exclusion criteria. Once diagnosed to have posterior capsular opacification they were subjected to a detailed clinical examination. All patients underwent Nd:YAG laser capsulotomy. Patients were followed up at 1 hour, 4 hour, 1 day, 1 week, 1 month, 3 month. At every follow up detailed examination was done. BCVA and any complications were noted. <strong>Results:</strong> Post-laser, 87% patients had BCVA 6/12 or more at 3 month follow up. 10% patients had BCVA 6/24 to 6/18. Only 3% patients had visual acuity improved to less than 6/24. Out of 3 patients, 1 patient had visual acuity improved to 6/60&amp;in remaining 2 visual acuity improved to 6/36. The complications were seen in 31 (31%) patients. Most common complication observed was transient rise in IOP. 17 eyes (17%) had transiently raised IOP. Second most common noted was pitting of IOL. Pitting was present in 7 (7%) patients, 3 (3%) patients had ruptured anterior face of vitreous, 2 (2%) patients had iritis, 1 (1%) had hyphema and 1 (1%) developed CME. IOP rise was related to grade of PCO and energy used.<strong> Conclusion:</strong> Improvement in visual acuity after Nd:YAG laser posterior capsulotomy is excellent. Complications associated with Nd:YAG laser capsulotomy are minimal. Nd: YAG laser capsulotomy is a safe method of restoring vision in patients with posterior capsule opacification.

Introduction: Cataract is most common cause of curable blindness worldwide and cataract surgery is most common procedure performed in ophthalmology. Posterior capsular opacification (PCO) is most common complication after cataract surgery which is usually treated with Neodymium-doped: Yttrium Garnet (Nd:YAG) laser posterior capsulotomy or occasionally with a surgical capsulotomy. The incidence and severity of PCO correlates to the type of surgical technique, IOL optic edge designs and IOL materials. Material and Methods: 70 eyes of 64 patients operated for age related cataract were studied in this prospective interventional study. Phacoemulsification was done in 35 eyes and SICS in 35 eyes with hydrophobic single piece biconvex foldable intraocular lens. Patients were followed up at 1, 3, 6, 9 and 12 months for the development of PCO. Clinically significant PCO (loss of 2 or more lines of Snellen’s visual acuity chart) was treated with Nd:YAG laser capsulotomy. Results: The overall incidence of PCO was 22.85%. Amongst the patients who developed PCO, SICS and phacoemulsification was performed in 62.5% and 37.5% patients respectively. Result was statistically significant with p value <0.05 using z test. On first postoperative day, patients operated with phacoemulsification had better visual acuity than SICS. Conclusion: Phacoemulsification can provide early and better visual outcome than SICS and has lower incidence of PCO formation which may be due to difference in irrigation and aspiration and less disruption of blood aqueous barrier than SICS. PCO can be reduced by atraumatic surgery and thorough cortical clean up and capsular polishing.

A longitudinal study was carried out in the laser unit of the Combined Military Hospital (CMH), Dhaka on 500 eyes of 500 patients who were treated with Neodymium-yttrium-aluminium-garnet (Nd:YAG) laser capsulotomy over a period of two and a half years. The aim of this study was to evaluate the visual acuity following Nd:YAG laser capsulotomy. The main entry criteria for this study were posterior capsular opacification (PCO) following Extracapsular Cataract Extraction (ECCE). The patients with corneal opacity, glaucoma, vitreous opacity, macular diseases, optic nerve diseases and any other retinopathies causing visual impairment were excluded from this study. Thirty six percent patients had pre-capsulotomy visual acuity 6/36 to 6/60, 32% patients had 6/18 to 6/24, 18% patients had <6/60 and 14% patients had 6/12. After seven days of capsulotomy 76% patients gained 6/12 or better vision. Eighty percent patients gained visual acuity of 6/12 with optical correction after thirty days. On the other hand, 64% patients had pre-capsulotomy near vision < N10 and 16% patients had N8. After capsulotomy near vision improved considerably. Four percent of the patients failed to improve vision following laser capsulotomy. It can be concluded that Nd:YAG laser capsulotomy in PCO can improve both distant and near vision, which can be augmented with optical correction after one month of laser surgery.

Abstract Background:CBS is a rare phenomenon which is found during and after cataract surgery. The mechanism, OCT presentation and clinical characteristics are not well studied. Methods:Document patients with CBS who underwent examination, including refraction, best-corrected visual acuity, slit lamp, anterior segment OCT, and onset after cataract surgery. All patients underwent Nd:YAG laser capsulotomy and were prescribed a low-dose topical steroid for seven days. Post-capsulotomy refraction and visual acuity were recorded.Results:This study included 18 eyes. Patients’ mean age was 80 (range, 54–92). The duration between cataract surgery and CBS diagnosis ranged 15–136 months. According to anterior segment OCT findings, we subcategorized the patients into four types: minimally opaque (n=4, 22%), uniformly turbid (n=7, 39%), focally condensed (n=5, 28%), and diffused sparkling (n=2, 11%). After laser capsulotomy, mean visual acuity improved 0.18 ± 0.09 on the LogMar. A significant difference in absolute refraction changes between the groups was noted— maximum in the focally condensed and minimum in the uniformly turbid types. No patient developed complications or needed further treatment for CBS during mean follow-up of 80 months.Conclusion:High-resolution anterior segment OCT is useful for analyzing pathological changes in the CBS. Our study implies that these four types of CBS presentation indicate various causes of late-CBS formation, as well as distinct clinical presentation and post–laser capsulotomy outcome. In addition, YAG laser capsulotomy is a safe late-CBS treatment modality.

INTRODUCTION: Pediatric eye care, including cataract surgery, has become much more common in Nepal in recent years in tertiary facilities such as the Lumbini Eye Institute (LEI). This study provides the first report of visual outcome and complications after cataract surgery at that Institute. MATERIAL AND METHODS: This is a prospective observational study of all cataract surgical patients <16 years of age between March 1, 2011, and February 28, 2012. Visual outcome was assessed by two optometrists with pediatric eye care training. Clinical data were gathered in a specifically designed pediatric eye program database and demographic data were taken from hospital administrative records. RESULTS: In 2011-12, 334 children (248 boys [74%]) underwent cataract surgery, including 89 Nepali (27%) and 245 Indian (73%) children. In total, 320 (96%), 270 (81%), and 190 (57%) attended their first, second and third follow up visits respectively. Pre-operative visual acuity was <6/60 (91%), 6/60 to <6/18 (7%) and >6/18 (2%). Post-operatively, visual acuity was <6/60(27.5%), 6/60 to <6/18 (36.5%) and 6/18 or better (36%). The mean best corrected visual acuity was 6/38 first follow up, 6/34 second follow up, and 6/30 third follow up. Intraoperative complications were 1.6% pupillary capture and post-operative complications were 35.3% posterior capsular opacification (PCO). CONCLUSION: For 63% of children, visual acuity significantly improved with cataract surgery beyond their presenting vision of <6/60, with over 38% of children achieving visual acuity (>6/18). Follow up beyond one month needs significant improvement to treat postoperative complications particularly posterior capsular opacification.Journal of Universal College of Medical Sciences (2015) Vol.03 No.02 Issue 10Page: 35-38

To analyze the visual outcome in patients with pseudoexfoliation and to know the surgical parameters to cogitate in patients with pseudoexfoliation syndrome. An Observational study which was conducted in the Ophthalmology department in a tertiary care hospital in a rural area from June 2019 to December 2019. A total of 52 eyes of 52 patients aged 40 years and above, of either sex, clinically diagnosed with senile cataract and associated with pseudoexfoliation were enrolled in the study. After assessing best corrected visual acuity (BCVA), a detailed anterior and posterior segment examination was performed along with lacrimal sac syringing, manual keratometry, contact A-scan biometry and intraocular lens (IOL) power was calculated. All patients underwent manual small incision cataract surgery under peribulbar anaesthesia and intraocular lens was implanted. Intraoperative complications were noted during the surgery and was reported .Best corrected visual acuity was recorded on day 1, at 1week and at 1 month of follow up. Out of 52eyes of 52 patients, 29 were females (55.76%) and 38 eyes (73.07%) exhibited bilateral involvement. Distribution of the PXF material in various ocular structures was observed and majority of them (36.53%) had PXF material equally in iris, pupillary margin and lens. Based on the morphology of cataract associated with psudoexfoliation, nuclear cataract was the most commonly observed in 16 eyes (30.76%) and 42 eyes (80.76%) had moderate pupillary dilatation. The intraoperative difficulties observed during cataract surgery was poor pupillary dilatation which was managed by controlled sphincterotomy during the surgery in 3 eyes (5.76%), Iridiodialysis, rhexis extension, zonular dialysis each in 1 eye and posterior capsular rent in 2 eyes. Around 92.30% of the total study population achieved post-operative BCVA of 6/12 or better at 1month of follow up. Decreased visual acuity was noted in 2 (3.84%) eyes due to persistent corneal edema, one eye (1.92%) had posterior capsular opacification and one eye (1.92%) had cystoid macular edema. This study concludes that with careful preoperative assessment and necessary intraoperative precautions, good visual outcome can be achieved in patients with cataract with pseudoexfoliation.
