Peroxide contact lens care solution

摘要

A contact lens disinfecting solution that comprises 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 disinfecting hydrogen peroxide solution slows the rate at which the hydrogen peroxide is neutralized, particularly during the initial two hours, by a catalyst element that includes a P-metal. This reduction in rate of peroxide neutralization provides a more effective solution for killing certain microorganisms and fungi.

主权项

1. A contact lens disinfecting system comprising:
a contact lens, peroxide disinfecting solution comprising 0.5 wt. % to 6 wt. % hydrogen peroxide or a chemical precursor of hydrogen peroxide; and a P-metal modulating compound, wherein the P-metal modulating compound is taurine, and the molar concentration of the P-metal modulating compound is less than the molar concentration of the hydrogen peroxide in the disinfecting solution; and a contact lens disinfecting apparatus comprising a container adapted to contain a quantity of the peroxide disinfecting solution, and a cap member that engages the container, the cap member including a lens supporting assembly that includes a lens support structure and a catalytic element that includes a P-metal, wherein the P-metal modulating compound is present at an effective concentration of 0.08 wt. %-2.0 wt. % such that the catalytic element catalyzes the decomposition of the hydrogen peroxide in the disinfecting solution with a pseudo first-order, half-life of hydrogen peroxide over an initial sixty minutes of neutralization that is 1.25 times to 3 times greater with the P-metal modulating compound in the solution than in the absence of the P-metal modulating compound, and wherein the pseudo first-order, half-life of hydrogen peroxide over an initial sixty minutes of neutralization is from 12 minutes to 30 minutes.
