1. A corneal implant for correcting hyperopia, comprising:
- (a) a body formed of an optically clear, biocompatible, material having an index of refraction in the range of 1.36 to 1.39;
(b) the body being solid and having an anterior surface and a posterior surface that bi-meniscus in shape and joining each other at the periphery of the lens;
with the anterior and prosterior surfaces having different radii of curvature; and
(c) the thickness of the edge being less than about 15 micrometers;
wherein said body is configured to alter an outer surface of a cornea of an eye to correct refractive error of the eye when implanted in the cornea.

10. A method of implanting a corneal implant for correcting hyoperia, comprising the steps of:
-
(a) cutting away a portion of the outer surface of a cornea of an eye;
(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 range of 1.36 to 1.39, the body being solid and having an anterior surface and a posterior surface that are bi-meniscus in shape and joining each other at the periphery of the lens, with the anterior and posterior surfaces having different radii of curvature, the thickness of the edge being less than about 15 micrometers; and
(c) replacing the portion of the cornea that was cut away;
wherein the outer surface of the cornea is altered to corrected refractive error of the eye. - View Dependent Claims (11, 12, 13, 14, 15)
