Abstract
This invention relates to a method for removing lipid deposits from contact lenses of a polymeric material, particularly contact lenses wherein at least a portion of the polymeric material is an organosilicon compound, by contacting the contact lens surfaces with certain volatile methylsiloxane fluids such as octamethylcyclotetrasiloxane and thereafter removing the fluid and the lipids removed from the contact lens. This method is especially useful for removing lipid deposits from silicone elastomer contact lenses.
