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

Abstract: A power saw suitable for one-handed operation having a three-dimensional shaped body with a hand grip and a base defining multi-sided exterior configuration. An electric motor is supported upon a mounting plate and installed within the housing. A gear drive system extends from an exposed face of the mounting plate and a power supply communicates to the motor and operatively drives the gear system. A continuous cutting band is supported upon outermost projecting gear members associated with the gear drive system, such that the band projects from a plurality of arcuately configured exterior surfaces associated with the body. A cutting zone is established at each projecting location of the band to perform a ripping operation on a workpiece positioned within a selected cutting zone.

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: A system for advancing a workpiece in guided fashion towards a rotating blade associated with a saw or router table, the table including a fence securing a distance from the blade. A three-dimensional and elongated housing is secured upon the table, the saw being disposed between the housing and fence. The unit is laterally adjustable upon the table in directions towards and away from the blade, a width dimension associated with the workpiece generally corresponding to a distance between the housing and fence. A plurality of unidirectional rollers are incorporated into the housing, each of the rollers securing at linearly spaced intervals along the housing and each exhibiting a shaft supported and vertical axis of rotation, such that an outer radial edge associated with each roller contacts an associated side edge of the workpiece.

Abstract: A catheter system includes a structure defining a fluid passage and a distal orifice, the structure having a first coupling configured to connect to a second coupling of a fluid line of a dialysis machine. The catheter system further includes a first spring supported by the structure and being configurable between an expanded configuration and a compressed configuration. When the first spring is in the expanded configuration, the first spring extends through the distal orifice so that (i) a proximal part of the first spring is positioned within the fluid passage, and (ii) a distal part of the first spring is positioned outside of the fluid passage. When the first spring is in the compressed configuration, the first spring is positioned entirely within the fluid passage of the structure.

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.
