  • Publication number: 20110281968
    Abstract: Contact lenses, such as hydrogel contact lenses, are described. The present contact lenses include a lens body that is the reaction product of a polymerizable composition. The polymerizable composition includes one or more monomers and a crosslinker that crosslinks the one or more monomers during polymerization. The polymerization of the one or more monomers occurs in the presence of a hydrophilic polymer that is present in the polymerizable composition, which comprises a polymer of 2-methacryloyloxyethyl phosphorylcholine. The present lenses are capable of releasing the hydrophilic polymer from the contact lens for prolonged periods of time and also have a reduced surface friction compared to similar lenses without the hydrophilic polymer. The present invention also relates to packaging systems for use with such lenses and methods of producing such lenses.
