Abstract

Posterior capsule opacification(PCO) is a common complication of cataract surgery. The presence of a posterior chamber intraocular lens has been shown to decrease the incidence of the development of PCO. Moreover, there are evidences that the design of intraocular lens may also alter its development. Extracapsular lens extraction with implantation of posterior chamber lens were operated on a consecutive series of 230 eyes. These were evaluated in the viewpoint of PCO development after surgery. All were sulcus fixed and their optic designs were devided into two groups; a group of convex-plano lens with continuous laser ridge including convex-concave lens and a group of biconvex lens. The incidence of PCO was lower in convex-plano lens with continuous laser ridge group(6.7%) than that of boconvex lens group(18.9%). The incidence of Nd:YAG posterior capsulotomy marked 0.0% in continuous ridged group and 1.8% in biconvex group(p<0.05, p
