Effect of intraocular lens convexity on posterior capsule opacification

Abstract

X posterior group was significantly less than in the convex anterior group, 17.6% versus 29.3% (P value < 0.05). The type of posterior capsule opacification in the two groups was also different. In the convex posterior group, a smooth fibrous type of capsular opacification predominated; in the convex anterior group, epithelial proliferation and pearl formation as well as wrinkling of the capsule frequently occurred. The difference in opacification was reflected in the preoperative visual acuity: convex posterior 20/80, convex anterior < 20/200 (P < 0.05). aReprint requests to Thomas O.
