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.
Claims11
A method for disinfecting a contact lens comprising forming a bactericide having a limited period of bacteriological activity, said bactericide comprising a source of peroxide, a peroxidase within the classification E.C. 1.11.1-7 and a source of predetermined donor molecules adapted to act as a substrate for said peroxidase, storing said three components in a nonreacting state such that said bactericide is inactive;
- admixing the three components in a liquid carrier to cause a catalyzed reaction by said peroxidase for generating free radicals from said source of donor molecules;
- selecting the concentration level of said three components such that a substantial percentage of said peroxide is consumed during said catalyzed reaction;
- and immersing the contact lens into said solution substantially simultaneous with the admixture of all three components whereby bacteria present on said contact lens will be killed during said limited period of bacteriological activity.
