A hydrogel composition is disclosed which comprises water and a copolymer. In one embodiment, the copolymer is formed by reacting about 85% to about 99% by weight of at least one member selected from the group consisting of N,N-dimethylacrylamide, N,N-diethylacrylamide, N-methyl, N-ethylacrylamide and mixtures thereof; about 1% to about 15% by weight of at least one compound selected from the group consisting of alkyl acrylates, alkyl methacrylates and mixtures thereof wherein the alkyl group contains 1 to about 4 carbon atoms; and a minor, effective amount of at least one cross-linking agent. Such hydrogel compositions are effective as corneal inlays and onlays.
