Patent ID: 7753952

Claim:
A vision prosthesis comprising: an aberration correcting optical element having a surface that is shaped to a cornea of an eye, wherein the optical element comprises an optical medium having a characteristic function associated with refraction therethrough, the optical medium being configured such that the characteristic function compensates for aberration in the eye when the optical element is located near the cornea; a magnetic element embedded in the optical element, wherein the magnetic element comprises a first magnet at a first location on the optical element, the first location being selected to avoid intersection of the first magnet with a visual axis of the eye; a second magnet adapted to be implanted within the eye, the second magnet being disposed such that when the optical element is located over the cornea the second magnet is proximate to and aligned with the first magnet, wherein the second magnet is adapted to be implanted at a location in the eye selected from the group consisting of: within the conjunctiva of the eye; under the conjunctiva of the eye; within the cornea of the eye; and under the cornea of the eye; and wherein the optical element comprises a contact lens.
