PEY6 POSTERIOR CAPSULAR OPACIFICATION AND ND: YAG LASER TREATMENT AFTER CATARACT SURGERY IN FRANCE: COMPARISON ACCORDING TO INTRAOCULAR LENS WITH SQUARE EDGED OPTIC DESIGN

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.

Introduction: Posterior capsular opacification is caused by migration and proliferation of cuboidal epithelium from remnant of anterior capsule and equatorial part of the lens capsule. Posterior capsular opacification also called after cataract is a nagging post surgical complication following phacoemulsification or non phaco cataract surgery (small incision cataract surgery or conventional cataract surgery) ECCE with posterior chamber intraocular lens implantation. Posterior capsular opacification is actually misnomer. Though there are many factors suggested to reduced posterior capsular opacification. The incidence of PCO still exists considerably. Aims and Objective are to find out the visual improvement after Nd yag laser posterior capsulotomy. Materials and Methods: The prospective study was conducted in the department of ophthalmology of Ad-din Women Medical College Hospital, Dhaka, Bangladesh from June 2014 to June 2018. 175 patients of 189 eyes with significant PCO. Before laser capsulotomy all patients were assess by routine slit lamp examination, IOP measurement and posterior segment examination done for every patient for exclusion of Gross posterior segment pathology. Results: The study had female preponderance (58.86%). Most of the patients 165 were 40 to 80 years old (87.31%). The patients had pre laser visual acuity 6/9 to 6/18 (31.75%) 6/24 to <6/60 (68.25%). After laser capsulotomy functional visual acuity upto 6/8 were 169 (89.42%) and 6/24 to <6/60 were 20 (10.58%). The mean pre and post laser capsulotomy visual functional score were 54.45±36.44 and 94.16±50.36 respectively. Conclusion: Nd YAG laser capsulotomy is safe, non-invasive and effective procedure.

Background: Posterior capsular opacification (PCO) is the most frequent complication of cataract surgery. The objective of this study was to determine the frequency of acute rise of intraocular pressure (IOP) following Neodymium-Yttrium Aluminum Garnet (Nd:Yag) laser posterior capsulotomy. Materials & Methods: This cross-sectional study was conducted in the Department of Ophthalmology, HMC, Peshawar, Pakistan, from July-December 2016. Sample size was 325 selected by consecutive sampling technique. Inclusion criteria were all patients having significant PCO after uneventful cataract surgery with intra ocular lens implant. Demographic variables were sex, age groups and age in years. Research variable was presence of acute rise of IOP following Yag laser capsulotomy. Pre-laser assessment included slit lamp examination and recording of IOP with Goldmann applanation tonometer by a single ophthalmologist. IOP was measured 3 hours after Nd: Yag laser capsulotomy. Rise in IOP was labeled when IOP was ≥5 mmhg from baseline. Mean ±SD was used to express quantitative variables like age. Categorical variables were analyzed as frequency and percentage. Goodness-of-fit was applied to compare the frequency of acute rise in IOP between sample and population. SPSS-20 was used for data entry and its analysis. Results: Out of 325 patients, 170(52.3%) were men and 155(47.7%) were women. The mean age of the sample was 44.92 ±23.843 years. A total of 107(32.9%) patients were 20-39 years old whereas 218(67.1%) were 40-70 years. IOP was raised in 61 (18.8%) patients while in 264(81.2%) patients it was not raised. The frequency of acute rise in IOP after Yag laser capsulotomy was significantly different in sample compared to population. Conclusion: Men were more than women, especially of old age. The frequency of acute rise in IOP after Yag laser capsulotomy was significantly different in sample compared to population.

BACKGROUND Retinitis pigmentosa is a group of hereditary disorders characterised by difficulty of seeing at night, bony spicule pigmentation in mid retinal periphery, progressive visual field loss and abnormal electroretinogram (ERG) responses. Cataract surgery in patients with retinitis pigmentosa is associated with poor visual outcome with higher incidence of intraoperative and postoperative complications. This study was done to find the visual and surgical outcome of phacoemulsification and intraocular lens (IOL) implantation in patients with retinitis pigmentosa. METHODS This was a retrospective, non-comparative, observational study done at Regional Institute of Ophthalmology, RIMS Ranchi, India. Consecutive patients of retinitis pigmentosa who underwent phacoemulsification and IOL implantation between July 2015 to December 2019 were retrospectively analysed. Intraoperative and postoperative complications, visual and refractive outcomes were analysed. RESULTS Fifty six eyes of 48 patients (29 male, 19 female) with mean age 46.62 ± 8.45 years were included in study. Mean follow up was 17.92 ± 10.62 months. The types of cataract were posterior subcapsular in 30.35 %, cortical in 14.2 %, mixed in 51.8 % and nuclear sclerosis in 3.5 % of eyes. Intraoperative posterior capsular rent (PCR) was noted in 2 eyes (3.57 %) and zonular dehiscence in 3 eyes (35.35 %). Preoperative mean log minimum angle of resolution best corrected visual acuity (MARBCVA) was 1.45 ± 0.49 which improved to 1.24 ± 0.28 postoperatively at 4 weeks (P-value < 0.05). Postoperatively, vision improved in 46 (82.14 %) eyes, unchanged in 7 (12.5 %) eyes and worsened in 3 (5.35 %) eyes. Postoperative cystoid macular oedema (CME) was noted in 5 eyes (9.07 %). Significant posterior capsular opacification (PCO) was noted in 15 eyes (26.78 %) and anterior capsular phimosis was noted in 3 eyes (5.35 %). CONCLUSIONS Cataract surgery improves vision in most of the patients with retinitis pigmentosa. The incidence of PCR, zonular dehiscence, CME, PCO and anterior capsular phimosis is higher in these patients. KEYWORDS Retinitis Pigmentosa, Cataract, Capsular Phimosis
