Intraocular lens with ridges

摘要

An intraocular lens for implantation in the posterior chamber of the eye including an optic having a posterior surface and first and second ridges adjacent the periphery of the optic and projecting generally posteriorly from the posterior surface. The ridges are circumferentially spaced to define openings between the ridges. Fixation members are mounted on the optic for at least assisting in retaining the optic in the posterior chamber with the ridges in contact with the posterior capsule of the capsular bag to space the posterior surface of the optic from the posterior capsule. The fixation members have knees adjacent the periphery of the optic which facilitate insertion of the intraocular lens into the eye.
