Zusammenfassung: | A hydrogen peroxide solution for disinfecting contact lenses contains an effective amount of a vinylpyrrolidone polymer for increased residual hydrogen peroxide concentration when in the presence of a catalyst, thereby prolonging the effective life of the solution. Also, a kit for use in the disinfection of contact lenses comprising: a) an aqueous hydrogen peroxide solution, wherein the aqueous hydrogen peroxide solution comprising a vinylpyrrolidone polymer and hydrogen peroxide, and b) a container for holding a given amount of hydrogen peroxide solution, wherein the container containing a disc comprising a substrate and a catalyst coating thereon, wherein, when the given amount of hydrogen peroxide is added to the container to entirely submerge the catalyst coated disc, the aqueous hydrogen peroxide solution decomposes over a period time of six hours to provide a residual hydrogen peroxide concentration of less than 100 ppm. |
