Abstract
An optic for an intraocular lens with finished, molded radii on the anterior and posterior edges of the peripheral surface of the optic. The optic has a thin central optical zone and a surrounding annular ring having sufficient material to support haptics. The ring is thicker than the optical zone and, thus, recesses the posterior surface of the optical zone to provide a capsulotomy space. The present novel optic is produced by novel molding pins which are shaped to provide the finished molded radii on the edges of the optic so that the optic requires little or no post-molding finishing or polishing other than the degating and deflashing.
