-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
