  • STABILIZED FORMULATIONS FOR CONTACT LENSES
    Publication number: 20260109119
    Abstract: The present invention provides a silicone hydrogel contact lens formulation, comprising a polymerizable siloxane component, a hydrophilic N-vinyl amide monomer, triphenylphosphine (TPP) and one or more of anthraquinone blue tinting agent, a benzophenone UV-absorbing agent or a benzotriazole HEVL absorber; a silicone hydrogel contact lens formed from the polymerisation of the silicone hydrogel contact lens formulation; and the use of an anthraquinone blue tinting agent, a benzophenone UV-absorbing agent and/or a benzotriazole HEVL absorber to stabilise a formulation comprising a polymerizable siloxane component, a hydrophilic N-vinyl amide monomer and TPP.

  • CONTACT LENSES AND CONTACT LENS FORMULATIONS WITH REDUCED RIPPLING
    Publication number: 20250257177
    Abstract: The present invention provides a silicone hydrogel contact lens formulation, comprising a di-functional siloxane, a hydrophilic N-vinyl amide monomer and at least 0.10% (wt/wt) triphenylphosphine (TPP), a silicone hydrogel contact lens formed from the polymerization of the silicone hydrogel contact lens formulation and the use of TPP to improve the surface properties of a contact lens prepared from a formulation comprising a di-functional siloxane, and a hydrophilic N-vinyl amide monomer.
