Abstract
This invention relates to comfortable ophthalmic devices and methods of producing such devices by treating a polymerized ophthalmic lens with a polymeric wetting agent, wherein the ophthalmic lens does not comprise said polymeric wetting agent prior to its polymerization.
Claims4
An ocular device prepared by heating a polymerized ophthalmic lens to a temperature of at least about greater than 50° C. to about 150° C. with a packaging solution comprising a polymeric wetting agent selected from poly N,N-dimethylacrylamide, copolymers of poly N,N-dimethylacrylamide, and graft co-polymers of poly N,N-dimethylacrylamide, provided that the polymerized ophthalmic lens does not comprise said polymeric wetting agent prior to the polymerized ophthalmic lens's polymerization.
