  • Publication number: 20220047503
    Abstract: The present invention relates to a method to load a water insoluble phospholipid as nanoparticles to load into a hydrogel contact lens in autoclaving process during the hydrogel contact lens manufacturing process without an extra manufacturing step and without swelling the hydrogel contact lens with an organic solvent. The phospholipid nanoparticles loaded in hydrogel contact lens subsequently releases to the eye upon wearing.
    Type: Application

  • Patent number: 8318059
    Abstract: The present invention provides a method for producing a medical device, preferably an ophthalmic device, more preferably a contact lens, made of a stabilized poly(oxyalkylene)-containing polymeric material. The method of the invention comprises the steps of: curing, in a mold, a composition comprising (a) a prepolymer having at least one poly(oxyalkylene) unit, (b) a biocompatible organic multi-acid or biocompatible salt thereof in an amount sufficient to improve the stability of the poly(oxyalkylene)-containing polymer made from the composition, (c) optionally a photoinitiator or a thermal initiator, and (d) optionally one or more vinylic monomers, to form the medical device being less susceptible to oxidative degradation; and removing the medical device from the mold.

  • Patent number: 8062607
    Abstract: The present invention provides a lens care kit for disinfecting and cleaning contact lenses. The lens care kit of the invention allows customers to visually identify when their lenses are disinfected, clean, and ready to wear. The invention is relied on color change to indicate the readiness of disinfection and cleaning of contact lenses.
