Background: Posterior capsular opacification (PCO) is the most common long-term complication following cataract surgery, affecting 20-40% of patients within five years. Nd:YAG laser posterior capsulotomy is the definitive treatment for symptomatic PCO. This study aimed to evaluate visual outcomes and document the spectrum of complications following Nd:YAG laser capsulotomy at a tertiary care center serving a predominantly rural population. Methods: A retrospective observational study was conducted from December 2023 to March 2025 (16 months). A total of 123 eyes with clinically significant PCO following uneventful cataract surgery underwent Nd:YAG laser posterior capsulotomy. Pre-procedure and post-procedure best-corrected visual acuity (BCVA), intraocular pressure (IOP), laser parameters, and complications were analyzed. Follow-up was performed at immediate, 1 hour, day 1, week 1, week 4, and week 6 post-procedure. Results: The mean age was 62.47±9.86 years with female predominance (54.5%). Mean duration since cataract surgery was 26.84±14.62 months. Visual acuity improved significantly from 0.58±0.24 logMAR pre-procedure to 0.18±0.14 logMAR at 6 weeks (p<0.001), with 91.1% achieving improvement of ≥2 Snellen lines. Transient IOP elevation (>5mmHg) occurred in 26.8% at 1 hour, normalizing in 93.9% within 24 hours. Complications included anterior uveitis (15.4%), IOL pitting (4.9%), cystoid macular edema (2.4%), and no cases of retinal detachment. Mean total laser energy was 86.24±32.46 mJ. Higher total energy (>100mJ) was significantly associated with increased complication rates (p=0.008). Conclusion: Nd:YAG laser posterior capsulotomy is a safe and effective treatment for PCO with excellent visual outcomes. Using lower total energy and performing smaller capsulotomies minimize complications. Prophylactic IOP-lowering medication and close monitoring are recommended post-procedure.
