IOL PERIPHERAL SURFACE DESIGNS TO REDUCE NEGATIVE DYSPHOTOPSIA

摘要

An IOL (10) is disclosed that includes an anterior surface (14) and a posterior 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 the central region of the posterior surface cooperatively form an image of a field of view on the retina and the peripheral region of the posterior surface directs at least some light rays 'incident thereon (e.g., via refraction by the anterior surface) to at least one retinal location offset from the image so as to inhibit dysphotopsia.
