20080258322 | USE OF SURFACTANTS IN EXTRACTION PROCEDURES FOR SILICONE HYDROGEL OPHTHALMIC LENSES - Methods of producing silicone hydrogel ophthalmic lenses include contacting one or more delensed silicone hydrogel ophthalmic lens with a liquid composition that contains alcohol, water, and a surfactant. The methods can be steps of an extraction/hydration procedure used in the production of silicone hydrogel contact lenses. In some examples, contacting silicone hydrogel ophthalmic lens products with a liquid composition that contains alcohol, water, and a surfactant can significantly reduce or prevent surface distortion of the ophthalmic lens resulting from the extraction procedure.
