  • Look Inside

We reviewed the rate of posterior capsular opacification and Nd-YAG laser capsulotomy after intraocular lens (IOL) implantation surgery. The series comprised 100 eyes with biconvex IOL and 93 with convex-plano IOL. YAG laser capsulotomy became necessary in 4 eyes, 4%, with biconvex and 12 eyes, 13%, with convex-plano IOLs. We then classified the series into 2 groups: complete in-the-bag fixation and incomplete one, in which both loops lie in the capsular bag, but the optical edge is not fully covered by the anterior capsular edge. The incidence of YAG laser capsulotomy was: 3% for biconvex IOL with complete fixation, 9% for con-vex-plano IOL with complete fixation, 13% for biconvex IOL with incomplate fixation, and 57% for convex-plano IOL with incomplete fixation. A lower incidence of secondary cataract resulted after implantation of biconvex IOL.
