Clinical Study of Visual Outcome and Intraocular Pressure Changes Following Neodymium-doped Yttrium Aluminum Garnet Laser Capsulotomy in Post-operative Cataract Patients with Posterior Capsule Opacification
Journal Title: INTERNATIONAL JOURNAL OF SCIENTIFIC STUDY - Year 2017, Vol 5, Issue 9
Abstract
Background: The use of neodymium-doped yttrium aluminum garnet (Nd:YAG) laser procedure for posterior capsulotomy has been gradually replacing the surgical capsulotomy as it is less invasive, and can be performed as an outpatient procedure. Objectives: The objectives of the study were to analyze the clinical results in terms of visual outcome, intraocular pressure (IOP) changes, and complications following Nd:YAG laser capsulotomy in small incision cataract surgery (SICS) and phacoemulsification surgery with posterior chamber intraocular lens. Methods: The study was conducted in the Department of Ophthalmology, Government General Hospital, Kakinada. Over a period of 20 months, data of 100 numbers of post-operative patients coming with diminished vision due to posterior capsular opacification following cataract surgery were gathered after conducting Nd:YAG laser capsulotomy. Results: Complications in Nd:YAG laser are minimal and transient. Improvement of visual acuity (VA) was excellent following Nd:YAG laser capsulotomy in SICS and phacoemulsification surgeries. VA improved to 6/6 in 16 cases, 6/9 in 36 cases, 6/12 in 16 cases, 6/18 in 10 cases, 6/24 in 8 cases, 6/36 in 7 cases, and 6/60 in 4 cases. Conclusion: Nd:YAG capsulotomy is a safe procedure. Since significant pressure spikes occur, after laser procedure, it is important to put the patients on topical timolol maleate 0.5% drops. IOP after 1 h, 4 h, and 1 week is important. When the patient comes for follow-up after 1 week, 4 weeks, and 24 weeks, it is important to look for cystoid macular edema and retinal detachment and endophthalmitis.
