Abstract
An intraocular lens for insertion into a capsular bag in order to focus incoming light toward a retina and process for manufacturing thereof along with concomitant reduced glare and improved vision provides for a center lens portion of a lens for focusing incoming light toward the retina and the surrounding lens portion for mounting the lens within the capsular bag. A surface roughness disposed on the surrounding lens portion is provided for reducing the glare due to non-focused light directed toward the retina from the intraocular lens with the roughness having a roughness level of between about Ra 45 and about Ra 350.
