Nd:Yag Laser Capsulotomy

Background: Neodymium-doped yttrium aluminum garnet (Nd:YAG) laser capsulotomy is a relatively noninvasive procedure that is used in the treatment of posterior capsular opacification (PCO). PCO is caused by proliferation of lens epithelial cells which causes fibrotic changes and wrinkling of the posterior capsule and results in decreased vision, glare, and other symptoms similar to that of the original cataract. Objective: To find out the visual outcome after performing Nd:YAG laser capsulotomy for PCO. Materials and method: A prospective clinical trial was carried out in National Institute of Ophthalmology (NIO), Dhaka, Bangladesh from January 2010 to June 2011 on purposively selected 70 adult subjects of both sexes who developed PCO within 2 months to more than 2 years after extracapsular cataract extraction with posterior chamber intra ocular lens implant. After thorough pre laser assessment Nd:YAG laser capsulotomy was carried out with Zeis VISULAS YAG II through Zeiss slit lamp under topical anesthesia. Data were recorded and expressed as proportion. Results: Out of the 70 subjects 40 were male and 30 were female. The average time interval of cataract surgery and Nd: YAG laser capsulotomy was 23 months. Capsular fibrosis (57.04%) was the predominant type of PCO. The pre laser visual acuity (VA) of more than 61.06% of eyes was 6/36 or below while 41.12% had VA hand movements to finger count. After Nd:YAG laser capsulotomy VA of 6/18 or better was achieved in 63.9% of eyes while 9.94% recovered to 6/9 and 11.36% achieved 6/6. None of these eyes showed further deterioration in VA. Conclusion: Nd:YAG laser capsulotomy for PCO is safe, effective and a rewarding procedure for improvement of vision.DOI: http://dx.doi.org/10.3329/dmcj.v1i1.14971 Delta Med Col J.

Nd:Yag Laser Capsulotomy

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. Key words: Laser capsulotomy, Nd:YAG laser, visual acuity. DOI: 10.3329/jafmc.v5i2.4580 JAFMC Bangladesh Vol.5(2) (December) 2009, pp.29-31

A total of 143 anterior chamber (AC) intra-ocular lenses (IOL) of various designs were implanted in a five-year period and followed for 18 to 76 months. The lenses were inserted as a secondary implant after extracapsular cataract extraction (ECCE) complicated by vitrectomy, or after primary intra-capsular extraction. The complications (corneal edema, uveitis/glaucoma, extrusion/imbedding, cystoid macular edema), the final visual acuity and the need for removal of the IOL were analyzed. Only small differences were found between the different lenses but some association was found between complicated surgery (ECCE + vitrectomy) and a higher rate of complication, poorer visual outcome and more frequent need for IOL removal. Cystoid macular edema was encountered only in cases with complicated ECCE. A high percentage of other ocular pathologies was found among the cases, possibly implying that diseased eyes are more prone to surgical complications. An alternative to the AC-IOL in cases with a ruptured posterior capsule is the suture-supported posterior chamber IOL, but the flexible-loop AC-IOL may not yet be obsolete.

Objectives: To evaluate the management and visual outcome of cataract surgery in children. Study design: Descriptive. Material and Methods: This study included one hundred pediatric patients having cataracts over a periodof two year, from Is' January 2005 to 31 st December 2006, at the Department of Ophthalmology, SaiduTeaching Hospital, Saidu Sharif, Swat. Results: Age range was fourteen years and below. Sixty five (65%) patients were males and thirty five (35%) females. Sixty three (63%) patients had congenital or developmental cataracts and thirty seven (37%) had traumatic cataracts. Extracapsular cataract extraction (aspiration) was performed on 150 eyes. Postoperative visual acuity was recordable in 112 eyes. Acorrected visual acuity of 6/18 or better was obtained in50 (44.64%) eyes. Forty one (36.6%) eyes obtained visual acuity of 6/24 to 6/60, while in 21 (18.75%) eyesthe visual acuity remained below 6/60. The most common postoperative complication was development ofthick posterior capsule, which occurred in 51 (34%) eyes and vitreous loss in 10 (6.6%) eyes. Pupil blockglaucoma developed in 4 (2.66%) eyes. No case developed endophthalmitis. Posterior chamber IOL wasimplanted in 9 (6%) eyes. Conclusions: Management of cataracts in children is still a problem and delayed presentation leads to poorvisual outcome. The public should be educated to seek early treatment for childhood cataracts. Paramedicsand doctors should be made aware of the problem and its management. Management of unilateral cataractsis still a difficult problem. Therefore search should continue for better surgical approach and better methodsof correction of aphakia so as to achieve better visual outcome. Key words: Childhood Cataracts, Congenital Cataracts and Traumatic Cataracts.

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.
