ABSTRACT:
A system for disinfecting and cleaning hygienic articles, particularly contact lenses for the human eye, in which, during a first time span, a first container contains hydrogen peroxide solution which acts onto the hygienic article and subsequently, during a second time span, the hydrogen peroxide which adheres to the hygienic article is split up into water and oxygen under the action of a catalyst either in the first container or in a second container containing the catalyst. According to the invention, catalase is used as the catalyst. Through this, the speed and thoroughness of the removal of hydrogen peroxide residues after the disinfecting phase are substantially increased.
