| Abstract | ||||
| Background: Posterior capsule opacification (PCO) is a common complication of cataract surgery caused by the proliferation of residual lens epithelial cells. Nd: YAG laser capsulotomy is the standard treatment, but prior studies on refractive changes after capsulotomy are inconsistent. Aim: To evaluate refractive changes after Nd: YAG laser capsulotomy for PCO in pseudophakic patients. Methods: This prospective interventional case series included 69 eyes of 61 adult patients undergoing capsulotomy for PCO at two centers in Egypt from August 2022 to November 2023. Complete ophthalmic examination and automated refraction were performed before and after treatment. The mean spherical equivalent (SE) and cylindrical refractive errors were compared pre- and post-capsulotomy. Results: The mean SE refractive error showed a statistically significant myopic shift, changing from +0.42D pre-capsulotomy to -0.10D at 1-month post-capsulotomy (p < 0.0004). The mean cylindrical error also demonstrated a significant myopic shift, from -1.93D pre-capsulotomy to -2.50D at 1 month (p < 0.006). Best corrected visual acuity (BCVA) significantly improved from 0.30 logMAR pre-capsulotomy to 0.70 logMAR post-capsulotomy (p < 0.001). Conclusion: Significant myopic refractive shifts and improved visual acuity were observed after Nd: YAG capsulotomy for PCO. The myopic shift differed from studies showing no change or a hyperopic shift post-capsulotomy. Further studies are needed to clarify the refractive effects of this common treatment | ||||
