Compositions and methods to disinfect contact lenses

Abstract

Compositions and methods to disinfect contact lenses are disclosed. In one embodiment, the present composition comprises a cellulose decomposing enzyme component, e.g., lysozyme, and a hydrogen peroxide destroying component. The composition is structured so that the cellulose decomposing enzyme component is released in a liquid medium containing hydrogen peroxide before the hydrogen peroxide destroying component is released in the liquid medium. Such cellulose decomposing enzyme component is preferably effective to render hydrogen peroxide-resistant microorganisms, e.g., acanthamoeba cysts, which may contaminate the lens more susceptible to being killed by hydrogen peroxide.
