Effect of intraocular lens design on posterior capsule opacification after continuous curvilinear capsulorhexis.

We compared the effect of biconvex and convex-plano (posterior plano) intraocular lenses on posterior capsule opacification (PCO) following continuous curvilinear capsulorhexis (CCC) in 212 eyes. During the three years following surgery, the cumulative frequency of neodymium:YAG laser posterior capsulotomy, calculated with the Kaplan-Meier method, was significantly higher in patients in the biconvex group (32.5% by the third year) than in those in the convex-plano group (5.
