Abstract: A multifocal intraocular lens providing greater or lesser refraction in relation to the position of the head and eyes of a user. The lens body is inserted into an artificial capsule bag or into a fluid-filled enucleated natural lens capsule of an eye, wherein the lens body encompasses the optical axis of the eye and by movement of the lens body within the capsule, provides different greater or lesser refraction depending upon the position of the eye.

Abstract: In accordance with the present invention, a multifocal intraocular lens provides greater or lesser refraction in relation to the position of the head and eyes of a user. A multifocal intraocular lens body for insertion into a fluid-filled enucleated natural lens capsule of an eye is provided wherein the lens body encompasses the optical axis of the eye and provides different greater or lesser refraction depending upon the position of the eye.

Abstract: A surgical method of corneal reformation reduces the risk of trauma and shortens overall recovery while yielding improved visual acuity includes making a relatively shallow incision of no more than about 85 microns deep into the corneal epithelium, separating the corneal epithelial sheet from the underlying Bowman's Membrane using an epithelial separator or a specialized cannula, and lifting the epithelial sheet away from the ablation zone so that the Bowman's Membrane and underlying stromal bed can be reformed. Multiple surgical instruments include the optional use of vibration with an epithelial separator or cannula to separate an epithelial sheet from the cornea of no more than about 85 microns thick.

Abstract: In accordance with the present invention, a multifocal intraocular lens provides greater or lesser refraction in relation to the position of the head and eyes of a user. A multifocal intraocular lens body for insertion into a fluid-filled enucleated natural lens capsule of an eye is provided wherein the lens body encompasses the optical axis of the eye and provides different greater or lesser refraction depending upon the position of the eye. In a second embodiment, the lens body can be used with an artificial lens capsule implanted within an eye.

Abstract: A contact lens insertion device includes a syringe having a barrel and a piston slidably disposed within the barrel. The barrel is adapted for receiving a fluid which is drawn into the barrel and dispensed from the barrel through operation of the piston. A cup is attached to the syringe. The cup includes a concave surface adapted to receive a contact lens therein. The cup further includes a chamber in fluid communication with the syringe barrel. The concave surface of the cup includes an aperture in communication with the chamber, such that fluid or gel flows from the barrel through the chamber and cup aperture upon actuation of the piston to force the fluid or the gel to flow out of the cup aperture to thereby eject the contact lens from the cup.

Abstract: A laser (e.g., excimer laser) and masking apparatus performs controlled sculpting of eye surfaces, such as corneal surfaces. The masking system includes a single/multi-layer (e.g., metallic) coated substrate (e.g., fused silica) with multiple openings in the substrate of desired size, shape and spacing to control the power transmission of a laser used in conjunction with the mask. The power transmission is controlled through the use of diffraction and absorption. The power transmission can be attuned to a particular surface by using topographical information of the surface in question. The surgeon can observe the topographical information and then pattern the openings (size, number, shape, spacing) so that reshaping can be done with greater intensity (using larger or more openings) to remove more corneal tissue in areas that the surgeon feels need more reshaping.

Abstract: Corneal tissue and, in particular, Bowman's membrane is removed by abrading an annular zone of the cornea. The corneal tissue is abraded by rotating an abrading tool having an annular abrading surface in contact with the cornea. A corneal onlay can be attached to the abraded zone of the cornea.

Abstract: A trephine for cutting a groove in the cornea of an eye comprising a fixation member and a shaft having first and second blades mounted thereon. The fixation member includes a bearing, and the shaft is receivable within the bearing. The fixation member can be affixed to the eye, and the shaft, when received in the bearing, is rotatable in the bearing so that the blades can make cuts in the cornea. By making cuts in the cornea which intersect, a segment of the cornea can be removed to provide the groove.

Abstract: A trephine for cutting a groove in the cornea of an eye comprising a fixation member and first and second shafts having blades mounted thereon. The fixation member includes a bearing, and the shafts are sequentially receivable within the bearing. The fixation member can be affixed to the eye, and the shafts, when received in the bearing, are rotatable in the bearing so that the blades carried by the shafts can make cuts in the cornea. By making cuts in the cornea which intersect, a segment of the cornea can be removed to provide the groove.
