Abstract: Hydrophilic coatings for implantable ophthalmic lenses are disclosed. The coatings, which are applied to the edge surface of the ophthalmic lens, comprise a hydrophobic (meth)acrylic polymer and a hydrophilic polymer. When hydrated, the coatings reduce or eliminate edge glare.
Abstract: A handpiece having at least one set of piezoelectric elements. The piezoelectric elements are constructed of segments that produce both longitudinal and torsional motion. An appropriate ultrasound driver drives the set of elements at the respective resonant frequencies to product longitudinal vibration and torsional oscillation.
Abstract: An intraocular lens injector cartridge having a heat retention additive for helping the cartridge retain heat once the cartridge is warmed. Such additives can include an biocompatible material having high heat retention, for example, powdered gold.
Abstract: Methods and compositions for preventing or treating allergic diseases of the eye, nose, skin, ear, gastrointestinal tract, airways or lung and preventing or treating manifestations of systemic mastocytosis are disclosed. The compositions contain a mast cell stabilizing disulfide derivative as an active ingredient.

Abstract: An anterior chamber phakic lens made from an elastomeric, foldable, highly biocompatible material. The lens has a generally circular optic and integrally formed plate-style haptics, the haptics containing an opening into which project a pair of pincer arms. The pincer arms are sized and shaped so as to pull away from each other when the lens is folded, and are draw back toward each other when the folded lens is released and allowed to return to its unfolded state. Such movement allows the pincers to gather a small section of the iris so as to hold the lens in place.
Abstract: Novel disulfide derivatives useful for preventing or treating allergic diseases of the eye, nose, skin, ear, gastrointestinal tract, airways or lung and preventing or treating manifestations of systemic mastocytosis are disclosed. The disulfide derivatives act as mast cell stabilizers.

Abstract: A microsurgical instrument that includes a handle and a dissecting tip coupled to the handle is disclosed. The tip includes a blade having a generally elliptical three-dimensional geometry. The blade may include an edge having a first arc and an opposing second arc. When the instrument is used to form an intracorneal pocket for the implantation of an intracorneal optical lens, the curvature of the first arc allows the edge to dissect a first blind spot of the pocket, and the curvature of the second arc allows the edge to dissect a second blind spot of the pocket. The blade may also be formed with a first depression in its top surface and a second depression in its bottom surface. When the instrument is used to form an intracorneal pocket, the depressions reduce the drag on, and corresponding trauma to, stromal tissue.

Abstract: A microsurgical instrument having a handle and a dissecting tip coupled to the handle is disclosed. The handle includes a cannula for transporting surgical fluid. The dissecting tip includes a blade for dissecting tissue and an aperture for delivering the fluid. The instrument may be used to more effectively create an intracorneal pocket for the implantation of an intracorneal optical lens.
