ATMOSPHERIC PLASMA COATING FOR OPHTHALMIC DEVICES

摘要

The invention provides a method of making ophthalmic lenses with an enhanced quality and enhanced yield achieved by reducing mold separation force and lens-mold adhesion. The method comprises the steps of generating an atmospheric plasma flow from a working gas and controlling the continuity of the atmospheric plasma flow with a power generator, and, introducing the atmospheric plasma flow to a molding surface of a mold for making an ophthalmic lens (preferably contact lens, more preferably a silicone hydrogel contact lens) and increasing the surface hydrophobicity of the molding surface of the mold and thereby to reduce a mold separation force after molding a lens formulation in the mold.
