Abstract: The present invention uses 3 dimensional printer technologies to create specialized contact lenses by building up optical features onto a shell of a contact lens. In this context, a shell is a curved disk with the same radius of curvature on the front and back surface providing a spherical base curve to fit the cornea and no optical power on the front curve. Starting with such a shell, the present invention provides that the 3-dimensional printer is utilized to build optical features on to the front surface.

Abstract: The invention provides a silicone hydrogel contact lens including a hydrolyzable units. The hydrolyzable units can be converted by hydrolysis into a hydrophilic units which is capable of imparting the silicone hydrogel contact lens a hydrophilic surface without post-curing surface treatment. The invention also provides an actinically crosslinkable prepolymer including hydrolyzable units and use of the prepolymer of the invention. In addition, the invention provides a method for making wettable silicone hydrogel contact lens without posterior surface treatments other than hydrolysis.

Abstract: A pre-formed intrastromal corneal insert for use in treating Keratoconus and similar dystrophies and methods of using the same. An intrastromal insert of the present invention comprises a biocompatible polymer and may be used to adjust corneal curvature, thereby correcting vision abnormalities caused by disease or other surgical procedures. The insert may be comprised of a circular or semi-circular ring shape or a portion of a ring, or “arc”, encircling the anterior cornea within the frontal circumference of the cornea. The insert may be used in multiples to form complete arcs or to form constructs of varying thicknesses. The insert of the present invention possesses a cross section that results in a low scattering level of light.

Abstract: Intraocular lenses and methods producing the same are provided. The intraocular lens includes an optic and a haptic that are integrally formed together. The haptic has a polyimide coating. The polyimide coating promotes fibrosis in the surrounding eye tissue to enhance the anchoring of the IOL after it is implanted in an eye.

Abstract: A contact lens is disclosed having a front surface and a back surface. The lens contains a continuously varying aspheric surface on one or more of these surfaces.

Abstract: A method of forming a contact lens containing a colored ring that covers a portion of or the entire limbus area of the eye when the contact lens is worn. The method of forming the contact lens includes applying a colorant material in a limbal ring pattern to the surface of a one-sided contact lens mold, then filling the one-sided contact lens mold with a polymerizable substance, casting the substance thereby forming a molded surface containing a limbal ring pattern, and machining the opposite side thereby creating a finished side opposite the molded surface.

Abstract: A system and method for inspecting an optical component such as a hydrated contact lens in which the system includes an illuminator providing light to a receptacle supporting the optical component with a saline solution and an imaging sensing device such as an eye or a video camera detecting fluorescent light generated in the optical component or in some portion of the receptacle and blocked by the optical component. The system and method are particularly useful for inspecting optical components which have been produced to have ultraviolet-absorbing properties.

Abstract: A composition comprising a halopolymer, such as an ethylene/chlorotrifluoroethylene copolymer, an effective stabilizing amount of an ionomer, and an effective stabilizing amount of a compound such as a phosphite of an organic polyhydric phenol; a thioester; a phosphite; or a hindered phenolic antioxidant. Preferred ionomers are metal salts of ethylene-acrylic acid copolymers, and metal salts of sulfonated polystyrenes. The stabilized halopolymers have improved resistance to thermal degradation and suffer less discoloration when subjected to high melt processing or extrusion molding temperatures.
