Abstract: A protective foot covering for use primarily in hospital operating rooms by surgeons requiring use of surgical instruments having foot controls. The covering comprises an upper formed of a non-woven crepe material which is resistant to penetration by liquids. The sole is formed by three separate material layers; the outermost layer being formed from a water-proof plastic material, the middle layer being formed from a non-woven fabric material and the innermost layer being formed from absorbent terrycloth. The sole layers provide a cushioned protection against slippage, water penetration and piercing from sharp objects on the operating room floor while also allowing the required sensitivity between the surgeon's foot and the foot controls of the surgical instrument.

Abstract: A kit for practicing ophthalmic suturing technique simulates the anterior portion of a human eye having a torn iris. The kit comprises a workpiece having a planar board with two elastic bands attached at their ends to the board in spaced, parallel relation to one another whereby the lengths of the bands between their ends may be moved with respect to the board. A transparent dome is attached at its perimeter to the board in covering, centered relation to the elastic bands. The dome includes first and second, axially aligned holes formed therethrough with the common axis of the holes extending transversely to the longitudinal extensions of the bands. The space between the elastic bands represents a tear in the iris with the transparent dome representing the anterior portion of an eye. A length of simulated suture is manipulated through the holes in the dome to close the space between the bands using a suture handling tool in the shape of a hooked crochet needle.

Abstract: Surgical blades for use in ophthalmic surgery are shown to include a first shaft, a second shaft, connected to the first shaft at a predetermined angle and a tip, connected to the distal end of said second shaft. The tip associated with the micro-paufique blade has a tapered surface extending inwardly forming a continuous cutting edge which includes a front portion and first and second side portions. Rotation and transverse movement of the first shaft in relation to a scleral incision results in a subsurface scleral pocket. In a preferred embodiment the micro-paufique tip portion is generally circular shape around its outer periphery and the tapered surface extends radially inwardly and towards the bottom surface. The tip associated with the micro-keratome blade extends a distance along a central axis and includes first and second side portions substantially symmetrical to the central axis.

Abstract: Flexible, crosslinked polymeric compositions providing transparent hydrogels having a refractive index in the dehydrated (dry) state of at least about 1.53 and having equilibrium water content of at least 40% by weight of the polymeric gel for use an expansile intraocular lenses for surgical implantation. The dehydrated polymeric compositions are capable of hydration by natural fluids present in the eye to expand about 180% after implantation and in the fully swollen state have refractive indices of at least 1.40. They are prepared by polymerizing a multicomponent monomeric mixture consisting essentially of from about 50 to 75% by weight vinyl pyrrolidone, from about 3.25 to 12.5% by weight of 2-hydroxypropyl acrylate, from about 3.25 to 12.5% by weight of 2-hydroxyethyl methacrylate, from about 5 to 35% by weight of acrylamide and as a fifth component a crosslinking agent in an amount of from 1.

Abstract: A novel method for performing intraocular surgery is described in which a radial incision is first made in the sclera of the eye, a subsurface scleral pocket lateral and anterior to the radial incision is then created, the subsurface scleral pocket extending anteriorly to the cornea of the eye, and finally a transverse incision is made from the pocket through the cornea into the anterior chamber of the eye. Through these incisions a damaged lens can be efficiently and effectively removed and replaced with a new lens. Various post-operative benefits are observed as a result of employing this procedure.

Abstract: A device for reducing a dimension of an expansile hydrogel intraocular lens having an optic portion including two plate members for supporting the lens in a compressing chamber and actuateable towards one another to apply a compressive force to the optic to simultaneously dehydrate the lens and to reduce the cross sectional dimension of said lens to a dimension less than the maximum cross section in the hydrated state.

Abstract: This invention relates to a method for reducing all of the common refractive errors, myopia, hyperopia, and astigmatism in a reversible fashion and to a device for achieving same. More particularly, this invention relates to a method for reducing or eliminating nearsightedness by flattening the curvature of the cornea and to a method for reducing or eliminating corneal astigmatism by changing the out-of-round shape of the cornea to a round shape. All of the methods utilize a retainer ring permanently placed in the stroma of the cornea, the tensioning of the ring being controlled by a turnbuckle arrangement.

Abstract: In the preparation of an expansile, polymeric, hydrogel intraocular lens for small-incision surgery to replace a damaged natural lens, the step of subjecting the polymeric lens material capable of reversible deformation to a compressive force during the drying to cause the disk to deform so that at least one dimension of the lens material decreased, permitting the lens to be inserted in its deformed configuration into the smaller possible wound. An expansile hydrogel intraocular lens material simultaneously reduced in size through dehydration and deformed from its original configuration by compressive forces so that at least one of the dimensions is decreased, said material in its deformed and dehydrated state being stable at room temperature and capable of being stored, shipped, and implanted without refrigeration.

Abstract: An artificial intraocular lens for surgical implantation to replace a damaged natural lens in an otherwise functional eye of a patient is disclosed as having a dome-shaped central disc portion, haptic loops formed on said central portion, for centering said central portion after implantation, wherein the central portion is composed of a dry, solid hydrophilic material capable of hydration by the natural fluid present in the eye to expand after implantation to provide an optically correct lens, wherein the central portion has a cross-sectional dimension substantially less than that of the natural lens and wherein said haptic loops are configured such that said central portion is centered upon implantation and remains centered during expansion thereof, thus improving the vision of the patient.

Abstract: Improved artificial intraocular lenses for surgical implantation to replace a damaged natural lens in an otherwise functional eye of a patient are described; the improvement comprising forming the lens, so as to have a minimum diameter of about 2 mm and a maximum diameter of about 5 mm prior to implantation, which is less than the diameter of the natural lens, from a dry, solid, hydrophilic material capable of being hydrated by the natural fluid in the eye to expand after implantation to provide an optically correct lens having a suitable diameter from about 6 mm to about 14 mm, to permit implantation of the lens through an incision of minimal length corresponding to the diameter of the dry lens and thus restoring the vision of the patient with minimal trauma. The invention also includes the improved method of implantation through an incision of minimal length.
