Patent ID: 7387642

Claim:
An optic portion of an intraocular lens, the optic portion comprising a polymer that comprises: (a) one or more alkoxyalkyl methacrylate monomers and/or one or more alkoxyalkyl acrylate monomers that are incorporated in the polymer; (b) one or more hydroxyalkyl methacrylate monomers and/or one or more hydroxyalkyl acrylate monomers that are incorporated in the polymer; and (c) optionally, one or more crosslinking agents that are incorporated in the polymer, wherein the total combined weight of the one or more alkoxyalkyl methacrylate monomers and the one or more alkoxyalkyl acrylate monomers ranges from 75 percent to 99 percent based on the total weight of the polymer when dry, and the total combined weight of the one or more hydroxyalkyl methacrylate monomers and the one or more hydroxyalkyl acrylate monomers ranges from 1 percent to 25 percent based on the total weight of the polymer when dry; wherein the glass transition temperature of the polymer of the optic portion is below 35° C., and wherein the polymer of the optic portion comprises water, and the equilibrium water content is less than or about 5 percent based on the weight of the polymer after it is hydrated.
