  • Patent number: 7550418
    Abstract: An buffered aqueous contact lens disinfecting solution having much lower concentration of disinfecting agents, and less irritating to the eye. The solutions have a tonicity of 200 to 450 mOsm/kg, a pH of between 6 and 8, and a concentration of chloride ions below 1500 ppm. Despite having less than 1 ppm of antimicrobial, the solutions are effective against C. albicans within 15 minutes of contact.

  • Publication number: 20070161523
    Abstract: The present invention provides a lens care composition having a persistent cleaning-efficacy characterized by substantially maintaining the light transmittance at around 280 nm of a contact lens after at least 15 cycles of soiling with a soiling solution containing proteins and subsequent cleaning with the lens care composition of the invention. The lens care composition comprises at least one surfactant, a polyvinylpyrrolidone (PVP), a cellulose ether, and xylitol, wherein in combination with polyvinylpyrrolidone (PVP), a cellulose ether, and xylitol, the surfactant provides the persistent cleaning-efficacy.

  • Patent number: 6939511
    Abstract: A method and composition for disinfecting a contact lens is disclosed. The method includes treating a lens with an aqueous solution having reduced toxicity to the eye which contains an effective amount of a monoperphthalic acid compound in a concentration of less than about 0.5% by weight of the solution. The lens disinfecting solution is capable of disinfecting contact lenses without irritating the eye due to reduced toxicity of the composition.
