METHOD FOR MAKING COLORED SILICONE HYDROGEL CONTACT LENSES
摘要:
The present invention generally relates to a method for making made-to-order (MTO) or customized silicone hydrogel lenses which have printed images on and/or below lens surfaces. A preferred method of the invention comprises printing and curing an ink on the molding surface of a mold for molding a single-side molded lens blank, producing the single-sided molded lens blank having a molded surface corresponding to one of the anterior and posterior surfaces of the lens to be produced and having an image embedded in the lens body and below lens surface, and directly lathing the lens blank on the side opposite to the molded surface to form the other lens surface. Colored silicone hydrogel lenses produced according to the invention will be useful as daily wear lenses and extended wear lenses. The lenses will allow alteration or enhancement of a patient's eye color.
