A preparation for simultaneously conducting disinfection, neutralization and cleaning of soft contact lenses, and a method for using easily, efficiently, and safely the preparation. The preparation comprises a combination of a first preparation containing an iodine disinfectant and a protease with a second preparation containing a reducing agent and a foaming agent and having a coating for delayed release, and a nonionic surfactant is contained in at least one of the first and second preparations. Soiled soft contact lenses are kept in an aqueous solution yellowed or browned with iodine molecules, and, after the aqueous solution has become substantially colorless, the lenses are separated from the aqueous solution, thus facilitating a series of procedures, that is, disinfection, neutralization, and cleaning.
L'invention concerne une préparation qui permet la désinfection, la neutralisation et le nettoyage simultanés des lentilles cornéennes souples, ainsi qu'un procédé permettant d'utiliser facilement, efficacement et sûrement la préparation. Cette préparation comprend en combinaison une première préparation contenant un désinfectant à base d'iode et une protéase, et une seconde préparation contenant un réducteur et un moussant ainsi qu'un revêtement pour libération retardée, un tensioactif non ionique se trouvant dans au moins l'une des deux préparations. Les lentilles souples salies sont maintenues dans une solution aqueuse teintée en jaune ou en marron par les molécules d'iode et, une fois la solution devenue sensiblement incolore, on extrait les lentilles, facilitant ainsi plusieurs opérations, à savoir, la désinfection, la neutralisation et le nettoyage.
