Abstract

Introduction of sharp-edge optic intraocular lenses (IOL) and the development of the modern phacoemulsification technique have resulted in reduced rates of posterior capsule opacification (PCO). Posterior capsule opacification is the most common complication of cataract surgery and results from the proliferation and migration of residual lenticular epithelial cells. PCO decreases visual acuity and contrast sensitivity leading to disability as a result of glare. Neodymium: yttrium-aluminum-garnet (Nd: YAG) laser capsulotomy has utility in the treatment of PCO. The purpose of this study was to evaluate the influence of size and shape of Neodymium: Yttrium Aluminum Garnet (Nd: YAG) laser capsulotomy on visual acuity and refraction. No significant change in SE following capsulotomy was observed in any group. BCVA significantly improved in all groups following capsulotomy. In conclusion, our study shows that Cruciate shape capsulotomy with an opening of 3.5 mm or less provides the greatest improvement in visual function following Nd: YAG capsulotomy in patients who have had uncomplicated cataract extraction surgery.
