    摘要: A pair of intraocular lenses for restoring visual function to a patient with central field loss. The pair of intraocular lenses includes a first lens for implantation into a first eye of the patient to provide vision of targets located at a distance greater than five feet from the first eye and a second lens for implantation into a second eye of the patient to provide vision of targets at a distance less than twelve inches from the second eye. The first and second lenses each include a prismatic wedge for shifting retinal images to a functional portion of a retina of each respective first and second eye.

    摘要: Prismatic intraocular lenses are disclosed for restoring visual function to an eye having macular degeneration. The lenses each include a convex lens optic for receiving and focusing light rays, a prismatic wedge located posterior to the convex lens optic for receiving and directing light rays to a first portion of a retina of the eye, and means for in situ alteration of the optical characteristics of the intraocular lens to direct light rays to a second functional portion of the retina.
