  • Publication number: 20090295001
    Abstract: Systems and methods of manufacturing ophthalmic lenses, for example, silicone hydrogel contact lenses, are provided. The present systems and methods provide certain amounts of ultraviolet light to contact lens mold assemblies that comprise a silicone hydrogel precursor composition. For example, the systems and methods may provide ultraviolet light at an intensity from 20 ?W/cm2 to 4000 ?W/cm2. The ultraviolet light intensity can be provided as substantially uniform levels to provide consistent curing for batches of silicone hydrogel contact lenses.

  • Publication number: 20090009712
    Abstract: A contact lens having a rotational stabilization mechanism thereon, such as prism ballast, and a thickness profile that reduces the torque imparted on the lens by the action of the eyelids, especially for stabilizing toric lenses. The prism ballast is provided on one or more portions of the anterior face of the lens such that the lens body has a uniform thickness of within 10% along horizontal cross-sections. The anterior face of the lens may be segregated into a peripheral zone, an inner zone circumscribed by the peripheral zone, and a central optic zone. The prism ballast portion is provided within the inner zone, which may be further subdivided into a superior portion, an intermediate portion proximate the optic zone, and an inferior portion. The ballast portion increases in thickness along a superior-inferior line parallel to a vertical meridian, and has a substantially uniform thickness perpendicular thereto. The peripheral zone may be tapered, and have a rounded edge.

  • Publication number: 20080137076
    Abstract: A contact lens package includes a base member including a cavity dimensioned to accommodate contact lens and a liquid therein. The combination of the cavity, the contact lens, and the liquid cooperate to collimate partially collimated light directed toward a bottom surface of the cavity. The cavity can be sealed by attaching a removable sealing member to the base member around the cavity. Methods of inspecting ophthalmic lenses using the present packages are also described.

  • Publication number: 20080103288
    Abstract: The present contact lens treating systems and methods effectively remove extractable materials from contact lenses, for example, newly formed contact lenses, so that the lenses can be safely and conveniently worn, for example, for extended periods of time. Such treatment methods and the present extraction medium reprocessing methods allow lens treatment while reducing extraction medium losses, thereby reducing costs of these materials and the burden of such treatment on the environment. The present methods can also be useful for manufacturing a heat stabilized contact lens, for example, a water swelled contact lens including a Vitamin E component which is insoluble in the lens in a hydrated state.

  • Publication number: 20080024723
    Abstract: Devices and methods for improving vision are described. The vision of a person can be corrected using a corneal onlay or a lens positioned between an epithelial cell layer and Bowman's membrane of the person's eye. Wavefront aberrations are measured for the person's eye or eyes, and the aberrations are used to shape the corneal onlay to provide a desired vision correction power, or to shape the person's cornea.

  • Publication number: 20070292555
    Abstract: Contact lens molds and systems and methods for producing contact lens molds are described. The contact lens mold sections include two optical quality surfaces, a flange circumscribing at least a portion of the two optical quality surfaces, and an elongate member extending from the flange. Two mold sections can contact one another to form a mold assembly having a contact lens shaped cavity. The mold sections are structured to form a contact lens having an edge that does not require further physical modification before placement on an eye. Systems and methods are described which direct a molten polymeric material into cavities corresponding to the mold sections.

  • Patent number: 7262232
    Abstract: Ophthalmic lenses, such as corneal contact lenses, include a lens body made of a composition including a lens body made of a composition including a first crosslinked polymer material which is water swellable, and a second polymeric material, other than the first material, selected from water soluble polymeric materials, water swellable polymeric materials and mixtures thereof. The second material is physically immobilized by the first material. Such lenses provide increased water retention and/or increased water content and/or increased modulus and/or reduced friction which increases lens wearer comfort. Compositions and methods for providing such lenses and compositions are also provided.
