Patent ID: 6891010

Claim:
A hydrogel that is the hydrated polymerization product of a monomer mixture comprising a hydrophilic monomer, and a monomer of the formula: wherein: each R is independently an alkylene group having 1 to 10 carbon atoms which may have ether linkages between carbon atoms; each R′ is independently a monovalent hydrocarbon radical or a halogen substituted monovalent hydrocarbon radical having 1 to 18 carbon atoms which may have ether linkages between carbon atoms; each R 3 is hydrogen or methyl w and x are each ≧0; y is ≧1; w+x+y=2 to 1000; and R ″ is a fluorinated side chain of the formula —D—(CF 2 ) 2 —H, wherein z is 1 to 20, and D is an alkylene group having 1 to 10 carbon atoms which may have ether, carbonate, carbamate, ester or amide linkages between carbon atoms, wherein said hydrogel has an oxygen permeability of at least about 120 Barrers, a water content of at least about 20 weight percent, and a modulus no greater than about 97 g/mm 2 .
