Neodymium-YAG Laser Lysis of Retained Lens Cortex Following Phacoemulsification Cataract Surgery

Abstract

Background: Retained lens cortex following phacoemulsification cataract surgery can lead to visual disturbances and complications. Nd:YAG laser lysis is a minimally invasive technique for managing retained cortical material, potentially improving patient outcomes.

Aim: This study aims to evaluate the efficacy and safety of Nd:YAG laser lysis in clearing retained lens cortex after phacoemulsification cataract surgery.

Methods: A prospective observational study was conducted on 100 patients with retained cortical material post-phacoemulsification. Nd:YAG laser lysis was performed, and patients were assessed for visual acuity improvement, intraocular pressure (IOP) changes, and postoperative complications. Data were analyzed using SPSS version 23.0, with statistical significance set at p < 0.05.

Results: The mean best-corrected visual acuity (BCVA) improved from 0.6 ± 0.15 logMAR pre-procedure to 0.3 ± 0.10 logMAR post-procedure (p < 0.001). A transient rise in IOP was observed in 10% of patients, stabilizing within the follow-up period (p = 0.045). Mild anterior chamber reactions occurred in 12% of cases, resolving with topical steroids. No significant retinal complications or IOL damage were reported.

Conclusion: Nd:YAG laser lysis is an effective and safe procedure for managing retained lens cortex post-phacoemulsification, leading to significant visual improvement with minimal complications. It serves as a non-invasive alternative to surgical intervention.

Recommendations: Further studies with larger sample sizes and long-term follow-up are recommended to assess the sustained benefits and potential risks of this procedure.
