Abstract
The method comprises forming a bactericide having a limited period of bacteriological activity with the bactericide comprising three components including a peroxide, a peroxidase and a source of donor molecules adopted to act as a substrate for the peroxidase; storing the three components in a nonreacting state to maintain the bactericide inactive and admixing the three components in a liquid carrier to cause a catalyzed reaction by said peroxidase for generating free radicals from the source of donor molecules and immersing the contact lens into the solution simultaneously with the admixture. The concentration level of the three components should be selected such that a substantial portion of the peroxide is consumed during the catalyzed reaction.
