Abstract: The present invention includes without limitation a process for separating a hydrogel contact lens from at least one mold half selected from the group comprising the anterior half and the posterior half of a contact lens. The process comprising the step of contacting either the contact lens or the one half with a maximum of about 1000 ?l of a super-cooled fluid to create a temperature differential between the contact lens and the one half.

Abstract: The present invention, in one embodiment, is a process for extracting pre-polymer from a polymer lens. The process of one embodiment comprises the step of contacting the ophthalmic lens with a super-cooled solvent for a period of time sufficient to extract pre-polymer from the polymer lens.

Abstract: The present invention includes a process for cleaning a mold or mold half comprising contacting the mold or mold half with a super-cooled fluid under conditions effective to clean the mold or mold half.

Abstract: The present invention is a process for extracting pre-polymer from a polymer lens. The process comprises the step of contacting the lens with a super-cooled solvent for a period of time to increase the modulus of the contact lens. Thereafter the contact lens undergoes additional dry processing steps. By way of example, the dry processing steps include but are not limited to surface treatment, lens coating and polishing and/or edging of the contact lens.

Abstract: Disclosed in embodiments herein is a method of synthesizing device forming monomers using N-(Vinyloxycarbonyloxy)succinimide.

Abstract: A method for preventing or reducing interaction between a container and a polymeric article contained therein comprises oxidizing a surface of the polymeric article. The method is advantageously used to package ophthalmic devices in polymeric containers.

Abstract: The present invention is a process for extracting pre-polymer from a polymer lens. The process comprises the step of contacting the lens with a super-cooled solvent for a period of time sufficient to extract pre-polymer from the polymer lens.

Abstract: A lens with a colored portion is composed of a lens-forming polymer having a front lens surface and a back lens surface. A colorant is applied to at least one of these surfaces, and these surfaces may be coated with a coating layer composed of a material different than the lens-forming polymer. In the case of a cosmetic contact lens, the colorant may be applied in an annular ring pattern corresponding to an iris, so that the colorant pattern masks and changes the apparent color of the natural iris when the contact lens is worn.
