    Abstract: A method of cleaning and disinfecting a contact lens, comprising the steps of: preparing a disinfectant which is an aqueous solution containing an iodine-complex polymer, and a diluent which is an aqueous solution containing ethylenediamine tetraacetic acid and/or soluble salts thereof, and a nonionic surface active agent; mixing the disinfectant and the diluent to provide a mixed solution, such that an available iodine concentration of the mixed solution immediately after mixing is in a range of 0.01-50 ppm, and such that concentrations of the ethylenediamine tetraacetic acid and/or the soluble salts thereof, and the nonionic surface active agent in the mixed solution are in a range of 0.0001-1.0 w/v % and in a range of 0.01-1.0 w/v %, respectively; and immersing the contact lens in the mixed solution for cleaning and disinfecting the contact lens, resulting in gradual reduction of the available iodine remaining in the mixed solution, by the ethylenediamine tetraacetic acid and/or the soluble salts thereof.

    Abstract: A sterilizing solution for contact lenses particularly those formed of a hydrophilic polymer comprises (a) an alkali metal salt of formic acid, and (b) an iodophor selected from the group consisting of complexes of iodine with hydrophilic polymer and non-ionic surface active agent. The alkali metal salt and the iodophor are present in predetermined quantities such that the sterilizing solution contains sufficient alkali metal salt to reduce the available iodine level of the sterilizing solution to substantially zero within a period of from 30 minutes to 8 hours at a temperature of from 20.degree. to 25.degree. C. The iodophor and the alkali metal salt of formic acid may be packaged in solid or powdered form, particularly in unit doses, and made into solution at the point of use.

    Abstract: The present invention provides a combined formulation for disinfecting, neutralizing and cleaning a soft contact lens and a method using the same easily, efficiently and safely. The formulation is a one-solution type of combined formulation for disinfecting, neutralizing and cleaning a soft contact lens, which includes a first formulation that contains an iodine-based disinfectant and a proteolytic enzyme and a second formulation that contains a reducing and a foaming agent treated with a delayed release coating, and which contains a nonionic surfactant in at least one of the first and second formulations. A stained soft contact lens can be disinfected, neutralized and cleaned easily by holding it in an aqueous solution colored yellow or brown by iodine molecules and removing it from the aqueous solution after the solution becomes almost colorless.
