ABSTRACT:
A rimmed intraocular lens including an optic and a rim about the lens optic which has a finite width and height of a geometrical cross section. The rim provides for capture of the lens optic in the capsular bag and prevents the cutting or wearing through of the capsular bag. The rim can be attached to a meniscus lens optic, a bi-convex optic, or a plano-convex optic. The rim can be positioned up, equal, or down with respect to the planar access of the lens optic. The rim can be of the same material as the lens optic, or it can be of a different material to preclude edge effect and glare and joined to the lens optic.
