Abstract
Corneal implants and methods for producing such implants are disclosed. The present corneal implants comprise a lens body which is optically clear and is structured to be surgically attached in or on the cornea of a mammalian eye, the lens body including a hydrogel composition containing water, a collagen component and a polymeric material covalently bonded to the collagen component. The hydrogel composition has enhanced biostability relative to an identical hydrogel composition without the polymeric material.
