1. A corneal onlay, comprising:
- a clinically acceptable lens body having an anterior surface and a posterior surface, the lens body being effective in permitting a corneal epithelium to completely heal and cover the anterior surface of the lens body and in retaining an ophthalmically acceptable transparency after implantation of the lens body onto the cornea of an eye of a human patient.

49. A method of making a corneal onlay, comprising:
-
placing a polymerizable corneal onlay precursor composition in a cavity of a first corneal onlay mold member; placing a second corneal onlay mold member in contact with the first corneal onlay mold member to form a corneal onlay shaped cavity containing the polymerizable corneal onlay precursor composition, the second corneal onlay mold member being placed in contact with the first corneal onlay mold member within an amount of time effective in avoiding formation of surface features indicative of premature polymerization of the polymerizable corneal onlay precursor composition; and polymerizing the polymerizable corneal onlay precursor composition to form a polymerized corneal onlay. - View Dependent Claims (50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62, 63, 64, 65, 66, 67, 68, 69)

70. A method of improving vision of a patient, comprising placing a corneal onlay on Bowman'"'"'s membrane of the cornea of an eye of a patient,
wherein the corneal onlay comprises a clinically acceptable lens body having an anterior surface and a posterior surface, the lens body being effective in permitting a corneal epithelium to completely heal and cover the anterior surface of the lens body and in retaining an ophthalmically acceptable transparency after implantation of the lens body onto the cornea of an eye of a human patient.
-
78. A method for identifying a clinically acceptable corneal onlay for use in a human patient, comprising:
-
placing a potentially acceptable corneal onlay on a layer of epithelial cells on a cornea of an eye at a first position; identifying a clinically acceptable corneal onlay from a plurality of potentially acceptable corneal onlays, each located on a layer of epithelial cells on a cornea of an eye, if the onlay moves less than 0.25 mm from the first position.
