Abstract: A surgical handpiece having two coaxial tubes or channels mounted within a body. The first tube is used for aspiration and is smaller in diameter than the second tube so as to great an annular passage between the first and second tube. The annular passage communicates with a pumping chamber formed between two electrodes. The pumping chamber works by boiling a small volume of the surgical fluid. As the fluid boils, it expands rapidly, thereby propelling the liquid downstream of the pumping chamber out of the annular passage. The electrodes are insulated from each other.

Abstract: The invention is directed to the use of novel compounds, compositions and methods for the prevention and treatment of neuronal tissue damage in mammals. The novel compounds comprise an antioxidant and a NMDA antagonist activity.
Abstract: A tip for a liquefracture surgical handpiece. The tip uses at least two channels or tubes. One tube is used for aspiration and at least one other tube is used to inject heated surgical fluid for liquefying a cataractous lens. The distal portion of the injection tube terminates just inside of the aspiration tube and directs the heated fluid through an orifice in the wall of the aspiration tube opposite the injection tube. The handpiece may also contain other tubes, for example, for injecting relatively cool surgical fluid.
Abstract: The present invention relates to the pharmaceutical treatment of pain. In particular, the present invention relates to the topical use of kappa opioid receptor agonists and partial agonists for the prevention or alleviation of pain in the eye.
Abstract: A method of polishing articles comprising soft acrylic materials is disclosed. The method includes a polishing step and a cleaning step. In the polishing step a receptacle is charged with polishing beads of various sizes, alumina, sodium hydroxide, water, a surfactant, and the articles to be polished, and agitated for a period of time and at a speed sufficient to remove surface irregularities. The polishing step is completed below the glass transition (Tg) point of the acrylic article being polished but above 0° C. Following the polishing step, the polished articles are cleaned by rinsing them with water for a period of time to clean the surface of the polished articles.

Abstract: Intraocular lens coating compositions for reducing the risk of posterior capsule opacification are disclosed. The coating materials, which differ from the substrate material, consist essentially of at least two aryl acrylic hydrophobic monomers of the formula
wherein:
X is H or CH3;
m is 0-10;
Y is nothing, O, S, or NR wherein R is H, CH3, CnH2n+1 (n=1−10) iso OC3H7, C6H5, or CH2C6H5;
Ar is any aromatic ring which can be unsubstituted or substituted with CH3, C2H5, n-C3H7, iso-C3H7, OCH3, C6H11, Cl, Br, C6H5, or CH2C6H5.

Abstract: A control system for a surgical system that includes an irrigation fluid flow sensing capability. The sensing capability may be placed in the control console or in the handpiece. Irrigation flow measurements provided by the sensing capability allows the control system to vary irrigation pressure and/or flow, aspiration pressure and/or flow and power supplied to the handpiece more accurately than prior art sensors that monitor aspiration flow.
Abstract: In vivo polymerizable intraocular lens compositions which comprise substituted fluoroalkyl or perfluoroalkyl monomers having anionic, cationic, and/or nonionic surface active functionality in the unsaturated fluorophobic ends. The compositions are preferably cured by UV photoinitiation and are useful in repairing torn or detached retinal tissue or forming intraocular lenses in situ.
