A method of providing a polymerized ophthalmic lens, comprising, heating a polymerized ophthalmic lens after its polymerization, with a packaging solution comprising about 100 ppm to about 3,000 ppm of a wetting agent to a temperature of at least about greater than 50°C. to about 150° C., and the polymerized ophthalmic lens formulation does not comprise said wetting agent prior to its polymerization, wherein the packaging solution further comprises about 3700 ppm sodium borate.
An ocular device comprising a polymerized ophthalmic lens and a wetting agent, wherein said polymerized ophthalmic lens is heated after its polymerization, with a packaging solution comprising about 100 ppm to about 3,000 ppm of a wetting agent to a temperature of at least about greater than 50° C. to about 150° C. and the polymerized ophthalmic lens formulation does not comprise said wetting agent prior to its polymerization wherein the wetting agent is selected from the group consisting of poly(meth)acrylamides, poly(itaconic acid), hyaluronic acid, xanthan gum, gum Arabic, starch, polymers of hydroxylalkyl(meth)acrylates, and polyvinylpyrrolidone.
