  • Silicone hydrogels comprising high levels of polyamides
    Patent number: 10370476
    Abstract: Described are silicone hydrogels with high levels of polyamides exhibiting an excellent balance of physical, mechanical, and biological properties. The silicone hydrogels are formed from a reactive monomer mixture comprising: a hydroxylalkyl (meth)acrylate monomer; hydroxyl-containing silicone components; and a polyamide, wherein the polyamide is present in an amount greater than 15 weight percent, based on the total weight of reactive components in the reactive monomer mixture.
    Type: Grant
    Filed: May 31, 2017
    Date of Patent: August 6, 2019
    Assignee: Johnson & Johnson Vision Care, Inc.
    Inventors: Azaam Alli, Alexander Guzman
  • Silicone hydrogels comprising polyamides
    Patent number: 10371865
    Abstract: Described are silicone hydrogels that are more biocompatible than current ocular materials. The silicone hydrogels are formed from a reactive monomer mixture comprising: a mixture of hydroxyl substituted silicone containing components, at least one polyamide; and at least one hydrophilic monomer. The silicone hydrogels also display a desirable balance of properties, including clarity, oxygen permeability, wettability and desirable protein uptake.
