Abstract
In one aspect, an intraocular lens (IOL) is discloses that includes an optic having a central portion and a peripheral extension that partially surrounds the central portion. Once implanted in a patient's eye, the IOL's optic forms an image of a field of view with the peripheral extension inhibiting dysphotopsia. While in some embodiments, the peripheral extension provides focusing of light incident thereon, in other embodiments, it can include at least one textured surface for scattering the light or at least one opaque surface for preventing the light from reaching the retina. In other embodiments, the peripheral extension can include one or more translucent surface(s) for diffusing the light passing therethrough to inhibit dysphotopsia.
