Abstract
Prosthetic implants designed to be implanted in the cornea for modifying the cornea curvature and altering the corneal refractive power for correcting myopia, hyperopia, astigmatism, and presbyopia, and, in addition, such implants formed of a micro-porous hydrogel material.
Claims8
A corneal implant, comprising:
- a) a body formed of an optically clear, biocompatible material having inner and outer surfaces and an index of refraction substantially the same as that of corneal tissue;
- b) the body being solid and formed of a microporous hydrogel having irregular passageways for nutrient transport, the microporous hydrogel having micropores ranging in diameter from 50 Angstroms to 10 microns.
