摘要： A method includes placing a contact lens over a cornea of an eye. The contact lens includes a central convex disc, a peripheral curved portion that extends radially from the disc, an annular groove formed in the disc on the posterior portion, and one or more apertures formed in the groove. A drug substance is placed over the anterior portion of the contact lens. The groove is in contact with the cornea and is a depot for the drug substance. The groove is in fluid connection with the anterior portion of the lens via the one or more apertures. The drug substance moves in an undiluted manner to the groove and the contact lens holds the drug substance in contact with the cornea, unaffected by blinking or tear exchange, facilitating enhanced bioavailability to the cornea of the drug substance.

摘要： Ophthalmic lenses for correcting refractive error of an eye are disclosed. Ophthalmic lenses include an inner optic portion configured to be disposed over the optical region of the cornea and having a central portion disposed between an anterior portion and a posterior portion. The inner optic portions configured to at least partially diverge from the shape of the cornea to provide at least one lenticular volume between a posterior surface of the inner optic portion and the cornea. The central portion may be characterized by a thickness from 50 μm to 900 μm and a modulus form 20 MPa to 1500 MPa.

摘要： The present disclosure relates to sensor systems for electronic ophthalmic devices. In certain embodiments, the sensor systems may comprise a sensor such as an adjustable resistor configured in series with an eye of a user of the electronic ophthalmic device. The sensor systems may comprise a gain stage configured to amplify a signal indicative of a difference between a voltage drop across the eye and the adjustable resistor. The sensor systems may comprise an integrator configured to integrate the amplified signal. A resistance value of the adjustable resistor is configured to cancel a DC component of a resistance of the eye when an electrical current is caused to flow through the eye and the adjustable resistor. As such, the configured resistance value of the adjustable resistor is indicative of an impedance of the eye.

摘要： A lens comprises an internal cavity structure formed by dissolution of a soluble insert material. The internal soluble material may dissolve through a body of a lens such as a contact lens in order to form the cavity within the contact lens. The cavity within the lens can be shaped in many ways, and corresponds to the shape of the dissolved material, such that many internal cavity shapes can be readily fabricated within the contact lens. The insert can be placed in a mold with a pre-polymer material, and the pre-polymer material cured with the insert placed in the mold to form the lens body. The polymerized polymer may comprise a low expansion polymer in order to inhibit expansion of the lens when hydrated. The polymer may comprise a hydrogel when hydrated. The soft contact lens material comprises a sufficient amount of cross-linking to provide structure to the lens and shape the cavity.

摘要： An optical device for off-axis viewing includes a contact lens adapted for human eye wear. The contact lens includes a diffraction grating written into or on the contact lens. A peripheral light from a peripheral light source is diffracted by the diffraction grating so as to appear at about a same location as light from an ambient scene substantially in a direction of a central field of view. A wearer of the optical device for off-axis viewing sees simultaneously the peripheral light and the light from an ambient scene as superimposed at least in part over each other. A device-less method for correcting light direction from an ambient light source to a retina of a diseased or injured eye, and a remedial contact lens method for correcting light direction from an ambient light source to a retina of a diseased or injured eye are also described.

摘要： Methods for manufacturing an ophthalmic lens with an insert using voxel-based lithography techniques, wherein at least a portion of one surface may be free-formed from a reactive mixture are set forth herein. An ophthalmic lens precursor may be formed on a substrate with an arcuate optical quality surface via a source of actinic radiation controllable to cure a definable portion of a volume of reactive mixture, wherein the control may be on a voxel by voxel basis.

摘要： Apparatus and systems for an ophthalmic device having alignment features for a liquid filled layered stack to assemble are disclosed herein. An example apparatus may include first, second, and third optical elements arranged in a stack, with each optical element including alignment and separation features. The alignment and separation features may form a reservoir region and a dam region. The reservoir region may provide radial alignment to the first, second, and third optical elements such that an optical axis of each optical element is aligned, and the reservoir region may have a reservoir region gap formed between adjacent ones of the optical elements. The dam region, disposed radially outside of the reservoir region, may include a first dam formed due to the first and second optical elements being in contact, and a second dam formed due to the second and third optical elements being in contact, wherein the dam region determines a reservoir region gap width.

摘要： A contact lens constructed to limit the water transmissibility of at least one area of the lens while maintaining at least a minimum oxygen transmissibility. The water transmissibility maximum and oxygen permeability minimum are achieved by a predetermined lens thickness of a single lens material or by the use of two or more material layers.
