Abstract
Prosthetic implants designed to be implanted in the cornea for modifying the cornea curvature and altering the corneal refractive power for correcting myopia, and myopia with astigmatism, such implants formed of a micro-porous hydrogel material.
Claims31
A corneal implant for correcting myopia with astigmatism, comprising:
- (a) a body formed of an optically clear, biocompatible, material having an index of refraction substantially the same as that of corneal tissue;
- (b) the body having an outer ring-shaped portion that is solid and defines an opening;
- and
- (c) the body including a second solid portion that fills in a portion of the opening, the second solid portion being located in a position to be implanted under a flattened portion of an astigmatic eye.

A method of implanting a corneal implant for correcting myopia with astigmatism, comprising the steps of:
- (a) cutting away a portion of the outer surface of a cornea;
- (b) implanting a lens on the exposed surface of the cornea with a body formed of an optically clear, biocompatible, material having an index of refraction substantially the same as that of corneal tissue, the body having an outer ring-shaped portion that is solid and defines an opening, the body including a second solid portion that fills in a portion of the opening, the second solid portion being located in a position to be implanted under a flattened portion of an astigmatic eye;
- and
- (c) replacing the portion of the cornea that was cut away.

- (b) the body having an outer ring-shaped portion that is solid and defines an opening;
- and
- (c) the body having an outer edge with an outer edge with a thickness of the edge being less than about 15 micrometers.
