IOL PERIPHERAL SURFACE DESIGNS TO REDUCE NEGATIVE DYSPHOTOPSIA

摘要

An IOL (10) is disclosed that includes an anterior surface (14) and a pos terior surface (16) disposed about an optical axis (OA), where the posterior surface includes a central region (20) extending to a peripheral region (22 ). Once the IOL is implanted in a patient's eye, the anterior surface and th e central region of the posterior surface cooperatively form an image of a f ield of view on the retina and the peripheral region of the posterior surfac e directs at least some light rays 'incident thereon (e.g., via refraction b y the anterior surface) to at least one retinal location offset from the ima ge so as to inhibit dysphotopsia.
