LENS CONVERSION SYSTEM FOR TELEDIOPTIC OR DIFFRACTIVE CONFIGURATIONS

摘要

A supplemental intraocular lens (116) is provided for implantation in the eye to modify the lens system of the eye comprising the cornea and the natural lens (106) or an intraocular lens (104) already implanted in the eye, to create a modified lens system having teledioptic or other diffractive capabilities to correct for macular degeneration. To create the teledioptic lens system, the supplemental intraocular lens (116) has substantially no refractive power except for a high minus lens portion at its center. The supplemental intraocular lens (116), when implanted on the natural or previously implanted artificial lens in the eye and used without an external lens, allows light rays entering onto the retina of the eye as they would without the supplemental intraocular lens, thus providing unmagnified and peripheral unrestricted vision.
