Abstract: The system uses a tunable inductor in series with the piezoelectric crystal excitation transducer in the probe which has a flux modulation coil. The bias current through this flux modulation coil is controlled by the system. It is controlled such that the inductance of the tunable inductor cancels out the capacitive reactance of the load impedance presented by the probe when the probe is being driven by a driving signal which matches the mechanical resonance frequency of the probe. The resulting overall load impedance is substantially purely resistive. The system measures the phase angle and monitors the power level. The system uses this information to adjust the bias current flowing through the flux modulation coil to maintain the substantially purely resistive load impedance for changing power levels. This information is also used to adjust the frequency of the driving signal to track changing mechanical resonance conditions for the probe at different power levels.

The shaft tapers from a relatively thick section adjacent the handle to a relatively thin section adjacent the blade portion.

Abstract: A driver system for an ultrasonic probe using a tunable inductor in series with the piezoelectric crystal excitation transducer in the probe. The bias current through this flux moduation coil is controlled by the system such that the inductance of the tunable inductor cancels out the capacitive reactance of the load impedance presented by the probe when the probe is being driven by a driving signal which matches the mechanical resonance frequency of the probe. The resulting overall load impedance is substantially purely resistive. The system also adjusts the frequency of the driving signal to track changing mechanical resonance conditions for the probe at different power levels. This method of operation insures substantially maximum power transfer efficiency and substantially linear power control over a range of power dissipation levels.

Abstract: Compounds which enhance the efficiency of the corneal endothelial fluid pump thereby promoting normal corneal function and deturgescence of swollen corneas, and methods for the compounds' synthesis are described. In addition, surgical irrigating solutions which include one or more of the compounds are discussed along with methods for their use.

Abstract: Pharmaceutical compositions useful in the treatment of ophthalmic inflammation and methods of treating ophthalmic inflammation with those compositions are disclosed. The compositions contain a combination of a glucocorticoid and tetrahydrocortexolone. The tetrahydrocortexolone serves to substantially prevent any significant increases in intraocular pressure which might otherwise by experienced by the patient as a side effect of the glucocorticoid component of the compositions. The therapeutic interaction of the two components therefore allows the potent antiinflammatory properties of the glucocorticoids to be utilized without fear of elevating intraocular pressure. A method of preventing increases in intraocular pressure attributable to systemic or topical corticosteroid therapy is also disclosed. That method involves the administration of a pharmaceutical composition containing tetrahydrocortexolone to a patient receiving such therapy.

Abstract: Methods for preventing and treating corneal haze resulting from exposure of the eye to laser irradiation are disclosed. The methods include administration of compositions of wound healing modulators to the eye. Compositions for use in preventing and treating the corneal haze are also disclosed.

Abstract: Contact lens cleaning compositions containing a combination of an enzyme and a carboxy vinyl polymer, and a method of cleaning contact lenses with such compositions are described. The compositions are capable of cleaning soiled contact lenses very rapidly and completely due to a favorable interaction between the enzyme component and an abrasive precipitate formed by the carboxy vinyl polymer component when a small amount of the compositions is rubbed on the lenses.

Abstract: Disclosed are nonstinging, sustained release ophthalmic formulations to control intraocular pressure in antiglaucoma therapy comprising a basic active, a cation exchange resin, and, inter alia, an acidic, mucomimetic polymer.

Abstract: A means, method, and system for storing and caring for contact lenses, including cleaning, rinsing, storing, disinfecting, lubricating, etc., including a self-contained contact lens holder to support and contain one or more contact lenses. A fluid conduit is associated with the contact lens holder to provide a pathway for fluid to the chamber or chambers holding each contact lens. A fluid container holding a fluid used in contact lens care can be put in fluid communication with the fluid conduit and is operable to selectively introduce fluid into the fluid conduit and fill the contact lens holder with the fluid. The contact lens holder, fluid contact, and fluid container may all be incorporated in a unitary body, or fluid container and/or the fluid conduit can be selectively attachable to the contact lens holder so that different fluid containers can be interchangeable to the contact lens holder.

Abstract: A hand-held cannula assembly for irrigating and aspirating opthalmic surgical sites includes as irrigation cannula circumscribed about an aspiration cannula and extending out through the forward end of the assembly from a reservoir for the irrigation fluid in the handle. Pressurized irrigation fluid is supplied to the reservoir through the rearward end of the handle and flows through openings in the irrigation cannula periphery into an annular flow passage between the two cannulas. An opening in the irrigation cannula issues the irrigation fluid at the surgical site. Aspiration fluid is drawn into the aspiration cannula which extends through the handle interior to an outflow opening at the rearward handle end. The irrigation/aspiration tip exterior is made to be smooth, protrusionless, unitary and one-piece in design to afford a minimum in tissue tearing at the surgical site, while also allowing improved irrigation fluid flow a the site.

Abstract: A method for packaging intraocular lenses, contact lenses and other small, delicate devices which must be stored in a liquid is described.

Abstract: An apparatus and method for aseptic, particle-free production of articles. A shroud is placed around at least a portion of the device which produces the articles to substantially isolate that portion from the external environment. The device for producing the articles and the shroud are sterilized and the air inside the shroud is filtered and sterilized. A laminar or other type of flow of filtered, sterilized air is imparted through the shroud over the articles being produced. A secondary shroud encloses the corridor or work area adjacent the shroud and device which produces the articles. The corridor and secondary shroud are sterilized, and sterilized and filtered air is continually introduced therein. The articles therefore are particle-free and sterilized for further use. The apparatus and method can be used for any component production process employing high temperatures and/or pressures, including, but not limited to, blow molding, injection molding, and production of semiconductor electronic components.

Abstract: A dispenser for substances including solids, liquids, semi-solids, and gels including a forward member having a bore extending between its front and back opposite ends. The front end of the forward member consists of an application orifice. A rearward member is translateably movable with respect to the forward member and includes a plunger which is extendable through the back end of the forward member into the bore of the forward member. The plunger is slidable in the bore in response to movement of the forward section with respect to the rearward section. The substance, having been inserted into the bore, is then expelled from the application orifice in a precise and easily maneuverable manner. The dispensing means can be used with substances which are pre-packaged in capillary-type containers. The plunger can have different diametered sections which allow expulsion of the substance and then allow expulsion of the capillary-type container.
