Patent ID: 8011784

Claim:
A contact lens, comprising: a lens body which is the reaction product of a polymerizable composition, the polymerizable composition comprising one or more monomers, at least one crosslinker that crosslinks the one or more monomers during polymerization, and at least one polymer of 2-methacryloyloxyethyl phosphorylcholine, wherein said one or more monomers and at least one crosslinker form a first polymer component, wherein said at least one polymer of 2-methacryloyloxyethyl phosphorylcholine is physically entangled with said first polymer component in the lens body, and wherein the at least one polymer of 2-methacryloyloxyethyl phosphorylcholine is present in the polymerizable composition in an amount from about 1% to about 3% by weight.
