Abstract
The invention is directed to a method of cleaning and disinfecting a contact lens. The method includes instructing a consumer to disinfect their contact lens comprising the following steps: remove a contact from an eye and position the lens in a lens assembly that includes a cap member; add a disinfection solution to the lens case such that the lens is submerged in the solution upon closure of the lens case with the cap member. The disinfection solution will comprise 0.5 wt. % to 6 wt. % hydrogen peroxide or a chemical precursor of hydrogen peroxide, and a P-metal modulating compound. The presence of the P-metal modulating compound in the disinfection solution decreases the neutralization rate of the hydrogen peroxide. The disinfection system exhibits a pseudo first-order, half-life of hydrogen peroxide from 12 minutes to 30 minutes over an initial sixty minutes of neutralization following exposure of the disinfection solution to a catalyst comprising a P-metal. This reduction in rate of peroxide neutralization can provide a more effective solution for killing certain microorganisms and fungi.
