|20080269890||INTRAOCULAR LENS WITH PERIPHERAL REGION DESIGNED TO REDUCE NEGATIVE DYSPHOTOPSIA - In one aspect, the invention provides an intraocular lens (IOL) that includes an optic and a peripheral optical flange that surrounds the optic. The optic can form an image of a field of view on the IOL user's retina and the peripheral flange can inhibit dysphotopsia. By way of example, the peripheral flange can include at least one textured surface that is adapted to receive peripheral light rays entering the eye at large visual angles so as to cause their scattering in order to inhibit dysphotopsia, e.g., by preventing the formation of a secondary peripheral image or scattering some light to a shadow region between such a secondary image and an image formed by the IOL.||10-30-2008|
|20080269882||INTRAOCULAR LENS WITH ASYMMETRIC OPTICS - 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.||10-30-2008|
