An Evaluation of Best Corrected Visual Outcome (BCVA) after Nd-YAG Laser Posterior Capsulotomy in Patients of Posterior Capsular Opacification (PCO): A Prospective, Single Centre, Observational Study

Objective: Posterior capsular opacification (PCO) is a postoperative complication causing decreasedvisual acuity. This study aims to study the efficacy of Nd: YAG laser capsulotomy in posteriorcapsular opacification following cataract surgery by analyzing the visual outcome. Material andMethods: A prospective study included a sample size of 50 eyes of 37 patients with Posteriorcapsular opacification following uneventful cataract surgery with significantly decreased visual acuity.Detailed anterior and posterior segment examination was done, best-corrected visual acuity (BCVA)was recorded along with measurement of IOP. Posterior capsulotomy was performed using Nd: YAGlaser (Neodymium: Yttrium-aluminum–garnet) and patients were followed up. Visual acuity wasassessed and complications if any were recorded. Results: It was noted that 74% of the patients atthe end of 1st week and 78% of the patients at the end of 1st and 3rd month had significant visualimprovement following Nd: YAG laser capsulotomy. There was a statistically significant difference inPost Nd: YAG laser BCVA on follow up with P-value <0.001. Complications encountered were the risein IOP in 6% of the population at the end of 1 hour and 1st day of the procedure, iris bleeding wasnoted in 4% of the population, intraocular lens damage in 2 %, and cystoid macular edema in 2 %of the study population.

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.

Aims: To study the visual outcome following Nd:YAG laser posterior capsulotomy and to study the complications associated with Nd:YAG laser posterior capsulotomy. Material and Methods: 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. Results: 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&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. Conclusion: 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.

: Nd YAG laser is preferred method to manage thickened posterior capsule because it is an easy, non-invasive and an OPD basis procedure considering the comfort of the patients.: The present study was carried out with objectives to evaluate the safety profile of Nd-YAG Laser Capsulotomy mainly in terms of rise in intraocular pressure (IOP) and other intra as well as post-operative complications.This prospective observational study was carried out with prior Institutional Ethics Committee (IEC) approval and written informed consent from the participants at Ophthalmology Outpatients Department (OPD) of a tertiary care teaching hospital of western India, for the duration of two years from Oct’2015 to Sept’2017. A detailed ocular, systemic, family history was taken of all the enrolled patients with pre- and post-procedure evaluation of IOP by Goldman’s Applanation Tonometry, Slit lamp examination and Fundus examination by direct and indirect ophthalmoscopy. Capsulotomy was done using VISULAS YAG III laser of Zeiss company.The data was entered and tabulated in Microsoft Excel 2007 and analyzed. Data was analyzed by frequency distribution. The ‘p’ value was determined to finally evaluate and P <0.05 was considered as statistically significant.Acute transient rise of IOP up to 5mmHg or more (P value <0.001) was found in Nine cases which is highly significant compared with pre-procedural stage. Intraocular lens pitting was observed in Four cases. Cystoid macular edema was found in one case. Two patients developed mild iritis. Nd-YAG laser capsulotomy is an easy, practical modality to treat posterior capsular opacities, but is not a completely innocuous procedure. Nd-YAG laser capsulotomy is an easy, practical modality to treat posterior capsular opacities, but is not a completely innocuous procedure. Due precautions should be taken in pre- and post-procedural stages including medications, thorough counselling, proper focusing and steady fixation of the patients to minimise the complication.

Purpose. To evaluate efficacy and safety of primary vitrectorhexis for posterior capsulotomy in highly myopic patients undergoing refractive lens exchange. Methods. The study is a prospective nonrandomized interventional study. The study comprised 60 eyes of 60 myopic patients. All patients underwent refractive lens exchange (RLE) and foldable IOL implantation combined with primary posterior capsulotomy. We used a 23-gauge vitrectomy probe for the creation of the posterior capsule opening. We followed the patients for one year. Results. During surgery, the IOLs remained well centered in the capsular bag after creation of the capsulotomy. Postoperatively, we did not report any complications related to lens centration or changes in the posterior capsulotomy size. No eye required YAG laser posterior capsulotomy and no cases of retinal detachment (RD) occurred during the follow-up period. Conclusion. Primary posterior vitrectorhexis during RLE is an efficient method in preventing the occurrence of posterior capsular opacification (PCO) and the need for YAG laser posterior capsulotomy with its possible complications.
