Abstract
Compositions and methods for destroying hydrogen peroxide, for example, contact lens disinfecting amounts of hydrogen peroxide, are disclosed. The present invention utilizes non-mammalian-derived catalase, for example, catalase obtained as a result of the action of one or more microorganisms such as Micrococcus luteus, Aspergillus niger and mixtures thereof, to promote the destruction of hydrogen peroxide. Such non-mammalian-derived catalase has substantial advantages, e.g., enhanced stability, relative to bovine catalase, which is conventionally used in such contact lens-related applications.
