Effect of Anterior Chamber Depth on the Development of Post YAG LASER Capsulotomy Macular Edema

Abstract

Background:The most common long-term phacoemulsification cataract surgery complication is the opacification of the posterior capsule (PCO). This condition can lead to decreased vision, an impaired ability to distinguish between light and dark and the development of monocular diplopia as the result of posterior capsule opacification. Aim of The Work:To evaluate correlation between anterior chamber depth using Anterior segment OCT and assess macular thickness after YAG-LASER capsulotomy using macular OCT. Patients and Methods:The study included twenty eyes of twenty patients who had uncomplicated phacoemulsification and developed posterior capsular opacification Group(1), and 20 eyes of 20 patients who had successful phacoemulsification without complications and without PCO Group (2) were the control. They were from the Sayed Galal Hospital Ophthalmology outpatient clinic from June to December 2021 at Al-Azhar University's Faculty of Medicine. Results: The current showed that best corrected visual acuity, spherical error, and spherical equivalent improved after YAG-Laser capsulotomy and vision markedly improved at the last follow-up period with statistically highly considerable variation between the two periods (p<0.001), while the axial length decreased during the follow-up period with statistically different value between the two periods (p<0.05). Conclusion:The blood-aqueous barrier is damaged by YAG-LASER capsulotomy, releasing VEGFs and other inflammatory mediators. The anterior chamber depth was altered by inflammatory macular edema from Nd:YAG laser capsulotomy. Prophylactic therapy may not be needed.
