Patents by Inventor Kelly Kayi Tallau

Kelly Kayi Tallau has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Publication number: 20220299796
    Abstract: The invention is related to a method for producing soft contact lenses comprises a silicone hydrogel lens body and a composite coating thereon. The composite coating comprises: a plasma base coating which is chemically-attached directly onto the surface of the silicone hydrogel contact lens and functions as a fail-proof measure for ensuring the hydrophobic silicone hydrogel lens material to be shielded from any exposure to ocular environments even after at least 30 days of daily uses including daily waring and daily cleaning/disinfecting; and a relatively-durable lubricious hydrogel top coating for ensuring wearing comfort.
    Type: Application

  • Patent number: 10830923
    Abstract: The invention is related to a process for producing contact lenses that not only comprise a water gradient structural configurations, but also have a minimized uptakes of polyquaternium-1 and a long-lasting surface hydrophilicity and wettability even after being undergone a simulated 30-days lens care regime.

  • Patent number: 10526470
    Abstract: The invention is related to a cost-effective method for producing water-soluble thermally-crosslinkable hydrophilic polymeric materials. Resultant materials can find particular use in preparing a packaging solution used for packaging and autoclaving medical devices, especially contact lenses. Those packaging solutions are especially suitable for forming a relatively-thick and soft hydrogel coatings on contact lenses or medical devices according to an in-package-crosslinking (IPC) processes. The resultant non-silicone hydrogel coatings can have a superior lubricity (a friction rating of 0) with minimized or no surface cracking.

  • Patent number: 10449740
    Abstract: The present invention generally relates to a method for producing silicone hydrogel contact lenses having a stable lubricious coating thereon without involving use of organic solvent in post-curing processes.
