Abstract: A blister package for a contact lens is provided. A deformable slider supporting a lens is movable via pull-tab or hinge to lift the contact lens out of a lens well. The deformable slider can include a hinge connected to a flexible peel-away top of the blister package or connected to a pull tab that can be pulled to pull taut the deformable slider. A blister package is also provided that includes a hinged shell having a lateral opening opposite the hinge, and a deformable slider that is folded over onto itself and seals both a top chamber and a bottom chamber. By pulling a tongue of the deformable slider, which extends from the lateral opening, the deformable slider can be removed from the closed shell and the closed shell can be opened enabling access to the contact lens.

Abstract: A wettable silicone hydrogel contact lens having a low ionoflux and low evaporation is manufactured by curing a silicone hydrogel polymerizable composition in a contact lens mold comprising front and back lens-forming surfaces, where one of the lens-forming surfaces has a higher polarity than the other lens-forming surface.

Abstract: A blister package for a contact lens includes a base sheet and a sealing sheet. Either the base sheet or the sealing sheet includes a bowl, and the other sheet includes a dome and a sealing surface. The dome has a radius of curvature of about 13 mm to 19 mm and a height of less than 7 mm relative to the sealing surface. The dome is configured to protrude into the bowl to form a cavity. Related methods are also described.

Abstract: A multifocal ophthalmic lens has a surface that varies across at least a portion of the lens to form a surface power map. The surface power map comprises a spiral, with a power that varies substantially periodically both radially outwards from and angularly about an optical axis of the lens. A period of the radial variation is greater than 100 microns and a period of the angular variation is greater than 6 degrees. Methods of making and using the multifocal ophthalmic lens are also described.

Abstract: An ophthalmic lens for myopia control. A first surface of the lens varies across the lens to form a first surface power map. A second surface of the lens varies across the lens to form a second surface power map. Each of the first and second surface power maps comprise a spiral. The spirals formed by the first and second surface power maps twist in opposing directions. Related methods are also described.

Abstract: A multifocal ophthalmic lens wherein a first surface of the lens is shaped to form a surface power map and a second surface of the lens is shaped to form a second surface power map. The first surface power map and the second surface power map together form a lens power map. The first surface power map, the second surface power map, or the lens power map comprises a spiral. The spiral has a variation across at least a portion of the lens. Methods of making and using such lenses are also provided.

Abstract: A contact lens having antioxidant properties is described as well as methods of manufacturing the same. The contact lens can be present in a sealed contact lens package. The seal contact lens package can include at least a) a plastic base member having a cavity; b) a contact lens packaging solution in the cavity; c) a sterile, unworn contact lens immersed in the contact lens packaging solution in the cavity; and d) a cover that forms a liquid-tight seal with the plastic base member. As an example, the unworn contact lens is a silicone hydrogel contact lens having present therein vitamin E. The vitamin E is non-releasable from the unworn contact lens and the contact lens packaging solution has less than 1 ppm of vitamin E present. The vitamin E is trapped, embedded, absorbed, or non-covalently attached in the unworn contact lens.

Abstract: A flexible optical element adopting liquid crystals (LCs) as the materials for realizing electrically tunable optics is foldable. A method for manufacturing the flexible element includes patterned photo-polymerization. The LC optics can include a pair of LC layers with orthogonally aligned LC directors for polarizer-free properties, flexible polymeric alignment layers, flexible substrates, and a module for controlling the electric field. The lens power of the LC optics can be changed by controlling the distribution of electric field across the optical zone. Lens power control can be provided using combinations of electrode configurations, drive signals and anchoring strengths in the alignment layers.

Abstract: Methods are disclosed for manufacturing a coated contact lens that comprises a polymeric lens body comprising an acid group, a first coating polymer comprising a first amine group ionically bound to the acid group, and a second coating bound to the first coating polymer through covalent linkage between a nitrogen atom of a second amine group on the first coating polymer and an amine-reactive group of the second coating polymer. In some examples the lenses exhibit improved surface properties compared to uncoated lenses, such as reduced adhesion, increased wettability, increased lubricity, and/or increased lipid resistance.

Abstract: Methods, devices, and systems for moving wet ophthalmic lenses are described in which the ophthalmic lenses are first placed in wells of lens carriers and are centered by the structure of the wells. The carriers are then moved to a transfer module of a packaging system for transferring the ophthalmic lenses in blister packages. The transfer from the carriers to the blister packages are performed by a pick and place robot having pickup heads sized and configured for suctioning the ophthalmic lenses from the lens carriers.
