Abstract
An implant prosthesis and method for replacing a full or partial thickness of a cornea. The prosthesis includes a transparent lens portion, and a carrier of preserved tissue, preferably cornea. The lens is attached to the carrier which in turn is adapted for attachment to the eye wall.
Claims5
An ocular implant prosthesis having a transparent lenticule, a carrier comprising preserved tissue adapted for attachment to an eye, and a bioadhesive polyphenolic protein bonding the carrier to the lenticule.
An ocular implant prosthesis having a transparent lenticule made of biologically acceptable material, a carrier comprising an annular ring of preserved, denatured biological tissue, the outer periphery of said annular ring being adapted for attachment to the eye wall, and a bioadhesive polyphenolic protein bonding the inner circumferential surface of the carrier to the lenticule.
A method of surgically repairing the cornea comprising the steps of:
- (a) removing at least a partial, generally circular thickness of the eye wall;
- (b) attaching to an ocular prosthesis having a carrier of preserved, denatured biological tissue a transparent lenticule by forming a radially inwardly extending flange on the carrier and inserting the flange into a complimentary groove in the outer periphery of the lenticule;
- and
- (c) surgically attaching the ocular prosthesis to the eye wall, covering the area from which tissue was removed.
A method of surgically repairing the cornea comprising the steps of:
- (a) removing at least a partial, generally circular thickness of the eye wall;
- and
- (b) bonding a transparent lenticule to a carrier of preserved, denatured biological tissue of an ocular prosthesis by applying a thin layer of bioadhesive polyphenolic protein therebetween;
- and
- (c) surgically attaching the ocular prosthesis to the eye wall, covering the area from which tissue was removed.
