Abstract
Abstract An intraocular lens (10, 60, 100) adapted to be fixated to the periphery of either the iris or an opening in the capsular bag has an annular ring (12) including an upper flange (14), a lower flange (16), and an interconnecting inner wall (18). Disposed within the annular (12) is a substantially circular lens (26). Alternatively, the intraocular lens includes a substantially circular lens (62) with a substantially U-shaped channel (64) extending inwardly along the perimeter of circular lens (62).
