Abstract
A method of disinfecting a contact lens using hydrogen peroxide, which method comprises conducting the hydrogen peroxide treatment of the lens in the presence of an immobilized enzyme which catalyses the decomposition of hydrogen peroxide. The invention also provides apparatus and a kit for treating contact lens. Preferably the enzyme is catalase, which may be immobilized by adsorption, by absorption, by covalent binding or by antibody complexing.
Claims14
A method of disinfecting a contact lens, which method comprises treating the lens with a solution of hydrogen peroxide having a strength sufficient to disinfect the lens, and decomposing the residual hydrogen peroxide in the solution by exposure thereof to an enzyme which catalyses the decomposition of hydrogen peroxide, wherein the enzyme is immobilized to a surface in the solution and, whereby the hydrogen peroxide is decomposed without the need for removal from the solution of the enzyme.
A kit for disinfecting a contact lens comprising;
- a kit means containing
- a container for a contact lens;
- a solution having an amount of a hydrogen peroxide release agent adapted to provide an effective concentration of hydrogen peroxide in the container to disinfect the contact lens;
- and
- an effective amount of an enzyme immobilized to a surface of the container and capable of catalyzing the decomposition of hydrogen peroxide, wherein
- said effective amount of hydrogen peroxide may be decomposed by means of the enzyme without the need for removing the enzyme from the solution.
