Abstract
A self-contained apparatus for cleaning contact lenses comprising a deformable, non-abrasive material having an enzyme enriched layer for contact with the optical surfaces of the lenses. While in contact with the optical surfaces, the contaminants on the lens surfaces are enzymatically removed. Upon separation of the lenses and the deformable material, substantially all of the enzymes are retained on the deformable material, largely eliminating the need to perform additional operations to inactivate the enzymes or otherwise rid the lenses of residual enzymatic matter.
