  • Patent number: 5048727
    Abstract: A unit dose dispenser for dispensing a composition includes a compressible, air filled container in communication with an open end of a tube filled with the composition. The opposite end of the tube through which the composition is dispensed is sealed with a removable closure cap to maintain sterility of the composition prior to use. By removing the cap and applying external pressure to compress the container, air is forced to enter the tube and eject, by displacement, composition from the tube. To completely eject the predetermined dosage that completely fills the tube, the volume of air or other gaseous propellant within the compressible container is greater than the volume of the unit dose.

  • Patent number: 4961745
    Abstract: An intraocular lens for replacing the natural lens of an eye including a pair of flexible loops connected to and projecting from the optic portion on one side of the first axis, adapted for supporting the IOL in the eye. The loops include outer end portions that terminate outwardly from the peripheral edge and on opposite sides of the second axis. A stabilizing member(s) is connected to and projects from the optic portion on the other side of the first axis from where the loops are connected, adapted for stabilizing the IOL in the eye. The flexible loops and stabilizing member(s) is shaped and dimensioned so that when the loops are moved toward the peripheral edge the outer end portions do not extend beyond the stabilizing member(s).

  • Patent number: 4945089
    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.

  • Patent number: 4905819
    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.
