  • Patent number: 11947192
    Abstract: A contact lens comprising one or more microchannels for transport of liquid through the lens is provided. The contact lens can be made by contacting a curable composition with a microfiber that is insoluble in the curable composition; curing the curable composition to provide a polymeric lens body with the microfiber embedded therein; and contacting the polymeric lens body with a solvent to dissolve the microfiber.
    Type: Grant

  • Patent number: 7968018
    Abstract: Methods of producing silicone hydrogel ophthalmic lenses include contacting one or more delensed silicone hydrogel ophthalmic lens with a liquid composition that contains alcohol, water, and a surfactant. The methods can be steps of an extraction/hydration procedure used in the production of silicone hydrogel contact lenses. In some examples, contacting silicone hydrogel ophthalmic lens products with a liquid composition that contains alcohol, water, and a surfactant can significantly reduce or prevent surface distortion of the ophthalmic lens resulting from the extraction procedure. Some methods include subsequently contacting the silicone hydrogel ophthalmic lens with a liquid composition consisting essentially of water and a surfactant.
