Abstract |
This study was performed to evaluate the correlationship between posterior capsular opacification and optic configuration of intraocular lens in extracapsular lens extraction with In-the-bag implantation of posterior chamber lens. We retrospectively studied the 455 cases of cataract operations that were performed between January 1993 and January 1995. All were in-the-bag placement and their optic designs were divided into two groups: a group of biconvex lens and a group of convex-plano lens with continuous laser ridge. The incidence of PCO in bicovex lens group was 7.0% and that of convex plano lens with laser ridge group was 7.1%. The difference in the rate of posterior capsular opacification between two groups was not statistically significant. The incidence of Nd: YAG laser posterior capsulotomy revealed 0.0% in continuous ridged group and 2.6% in biconvex group(p>0.05). |
