摘要： The invention provides a method for producing coated silicone hydrogel contact lenses in a cost-effective manner. The method comprises treating the molding surfaces of polypropylene lens molds (or other hydrophobic plastic molds) with a vacuum UV or a corona plasma to increase the surface energies of the molding surfaces of the lens molds, cast-molding a silicone hydrogel lens formulation containing a relatively small amount of at least one carboxyl-containing vinylic monomer in the treated lens molds, and heating resultant cast-molded silicone hydrogel contact lenses in an aqueous coating solution comprising a water-soluble and thermally crosslinkable polymeric material to form a coated silicone hydrogel contact lens comprising a bulk silicone hydrogel material and a hydrogel layer covalently attached onto the bulk silicone hydrogel material.

摘要： Ophthalmic lenses for correcting refractive error of an eye are disclosed. Ophthalmic lenses include a deformable inner portion and a deformable peripheral portion. When disposed over the optical region of an eye, the inner portion is configured so that engagement of the posterior surface against the eye deforms the posterior surface so that the posterior surface has a shape diverging form the refractive shape of the epithelium when viewing with the eye through the ophthalmic lens. The rigidity of the inner portion is greater than the rigidity of the peripheral portion and the ophthalmic lenses are configured to allow movement relative to the eye upon blinking of the eye and to be substantially centered on the optical region of the cornea following the blinking of the eye. Methods of correcting refractive errors of an eye such as astigmatism or spherical aberration using the ophthalmic lenses are also disclosed.

摘要： A contact lens fluid delivery device having a liquid reservoir connected to a channel with a flow regulator is described. Other eye hydration and variable dioptric power contact lenses are described herein. Also described are implantable liquid delivery apparatuses having a liquid storage reservoir connected to a channel with a flow regulator. These devices and apparatuses are useful for specific, targeted delivery of therapeutic liquids within a subject. In some embodiments, the devices incorporate actuation chambers which provide a driving force releasing the fluid into the targeted area e.g., the eye. The actuation chambers described herein can contain phase change materials or osmotic chambers or a combination thereof to drive the release of fluid.

摘要： A microfluidic flow restrictor that uses micron-sized beads to impede flow is described. The flow rate can be adjusted by adding or removing the beads using injection needles through self-sealing ports, one injection needle injecting or aspirating beads and another injection needle pushing or pulling fluid from outside of a bead trap within the flow restrictor. In alternative embodiments, the beads or other filler material can be trapped in a manifold bead trap such that they block a subset of fluid channels of the flow restrictor, allowing fluid to flow freely through the rest of the fluid channels. The flow restrictor can be integrated with a contact lens or implantable medical device for use in dispensing liquid therapeutic agents at flow rates of microliters per minute or moving body fluids at a controlled rate from one part of the body to another.

摘要： One embodiment of a contact lens includes a lens body configured to fit directly on the surface of the eye and legible characters positioned on the lens body. Another embodiment of a contact lens comprises a lens body including polymeric material and a lens enhancing material (e.g., ink, silicone material, medicament material, and the like) encapsulated in the polymeric material. The lens enhancing material can be in the form of isolated sections distributed in the surrounding polymeric material. Methods of making contact lenses include forming a first lens layer including a first surface, forming a pattern on the first surface, and forming a second lens layer over the pattern.

摘要： One embodiment of an ocular lens includes a lens body configured to contact an eye where the lens body has an optic zone shaped to direct central light towards a central focal point of a central region of a retina of the eye. At least one optic feature of the lens body has a characteristic that directs peripheral light off axis into the eye away from the central region of the retina. Another embodiment of an ocular lens has at least one isolated feature of the lens body that has a characteristic of directing peripheral light off axis into the eye away from the central region of the retina. Methods of making contact lenses include forming the features during the manufacturing process.
