A method for 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, a swelling agent and the articles to be polished, and agitated for a period of time and at a speed sufficient to remove surface irregularities. Following the polishing step, the polished articles are cleaned by agitating them with a cleaning slurry comprising cleaning beads of various sizes, alumina, a solvent and a surfactant for a period of time and at a speed sufficient to clean the surface of the polished articles. Agitation is preferably accomplished by a tumbling machine.
摘要:
A method for attaching a pair of colored haptics to an optic of an intraocular lens, containing the steps of providing the peripheral edge of the optic with a pair of holes, inserting the end portions of the haptics into the holes, aiming a laser emitting radiation within the visible spectrum at the end portion of the haptic within the hole in the optic and firing the laser so that the radiation passes through the optic essentially without absorption and is absorbed by the end portion of haptic, thereby causing end portion to swell and mechanically anchor the haptic within the optic.
摘要:
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 create 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 distal end of the annular gap is sealed by sealing together the distal ends of the first and second tube and a plurality of orifices or ports may be formed near the seal. As the expanding gas is propelled down the annular gap, the gas/liquid stream is forced out of the distal orifices in a controlled and directed manner. The distal end of the first and second tubes may contain a bend.

Compositions and methods for treating ocular pain are disclosed. In particular, the invention discloses compositions and methods of using kappa opioid agonists topically for the prevention or alleviation of ocular pain.
摘要:
An intraocular lens injector plunger having a blunt, rounded tip offset from the centerline of the plunger rod. The offset tip assures that the tip is biased downward against the bottom of the cartridge bore. Such a downward bias helps prevent the tip from riding up over the IOL and being folded within the IOL. The offset also helps prevent the haptics of the IOL from becoming trapped between the plunger rod and the cartridge bore, thereby damaging the haptics and/or preventing the IOL from being advanced down the bore.
摘要:
A surgical handpiece having at least two lumens or tubes mounted to a body. At least one tube is used for aspiration and at least one other tube is used to inject heated surgical fluid for liquefying a cataractous lens. A portion of the second tube is enlarged to form a pumping chamber. 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 second tube. The pumping chamber may use a pair of electrodes.
摘要:
Improved saline solutions useful in treating contact lenses are described. Unlike prior saline solutions used for similar purposes, the present solutions do not contain conventional antimicrobial agents which are potentially toxic to ocular tissues. Rather, the solutions contain a combinaison of a borate-polyol complex, one or more anionic or nonionic surfactants, and a low molecular weight amino acid (e.g., glycine). It has been found that this combination effectively preserves the saline solutions from antimicrobial contamination, is relatively nontoxic to ocular tissues, and is compatible with oxidizing agents used in certain contact lens disinfecting systems. The combination also facilitates the cleaning of contact lenses.
