Patent ID: 8410190

Claim:
A method of manufacturing a hydrogel contact lens body, comprising: (i) providing a polymerizable composition comprising at least one polymerizable form of a boronic acid, boronic ester, boronic anhydride, or combination thereof; at least one hydrophilic monomer, and at least one crosslinking agent; and (ii) cast molding the polymerizable composition in a contact lens mold assembly to form a polymerized reaction product that is an uncomplexed hydrogel lens body formed of a copolymer comprising polymerized units of the at least one polymerizable form of the boronic acid, boronic ester, boronic anhydride or combination thereof, polymerized units of the at least one hydrophilic monomer, and crosslinks formed by the at least one crosslinking agent; wherein the uncomplexed hydrogel lens body has an advancing contact angle less than about 120°, a modulus less than about 1.6 MPa, an ionoflux less than about 7×10 −3 mm 2 /min., an oxygen permeability of less than about 120 Barrers, and an equilibrium water content of at least about 30%.
