摘要：
The invention provides a method for washing, with a water-based system, reusable molds for making silicone hydrogel contact lenses. The water-based washing system comprises an ethoxylated silicone polyether surfactant. The water-based system of the invention can effectively wash away silicone-containing components and other components of a lens formulation left behind on the molding surfaces of a reusable mold, after removing a silicone hydrogel contact lens cast molded in the reusable mold.
