A HYDROGEN PEROXIDE SOLUTION AND KIT FOR DISINFECTING CONTACT LENSES

摘要

The present invention relates to a hydrogen peroxide solution for disinfecting contact lenses. The hydrogen peroxide solution contains an effective amount of a homopolymer or copolymer of vinylpyrrolidone to an increased residual hydrogen peroxide concentration when in the presence of a catalyst, thereby prolonging the effective life of the solution and providing greater comfort to the weather. The present invention also relates to 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 homopolymer or copolymer of vinylpyrrolidone and an effectively disinfecting amount of hydrogen peroxide, and b) a container for holding a given amount of hydrogen peroxide solution, wherein the container containing a disc, wherein the 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.
