A method for disinfecting contact lenses, the method comprising:
- immersing the contact lenses in a volume of cleaning agent comprising about 3% hydrogen peroxide for up to 4 hrs;
- and
- increasing the disinfection efficacy of and creating stable hydroxyl groups in the hydrogen peroxide by immersing up to 0.7 g of a fibrous catalyst enhancer material in the volume of cleaning agent for up to 4 hrs, the fibrous catalyst enhancer material being immersed simultaneously with the contact lenses, wherein the fibrous catalyst enhancer material comprises covalently attached iron cation.
A method for disinfecting contact lenses, the method comprising:
- immersing the contact lenses in a volume of cleaning agent comprising about 3% hydrogen peroxide for up to 4 hrs;
- and
- increasing the disinfection efficacy of and enabling a stable equilibrium in the hydrogen peroxide by immersing up to 0.7 g of a fibrous catalyst enhancer material in the volume of cleaning agent for up to 4 hrs, the fibrous catalyst enhancer material being immersed simultaneously with the contact lenses, wherein the fibrous catalyst enhancer material comprises covalently attached iron cation.
