Title (EN) CONTACT LENS CLEANING SOLUTION AND METHOD FOR CLEANING CONTACT LENSES USING THE SAME
(FR) SOLUTION DE NETTOYAGE DE LENTILLES DE CONTACT ET PROCEDE DE NETTOYAGE DESDITES LENTILLES DE CONTACT AU MOYEN DE CETTE SOLUTION
Abstract: front page image
(EN)A contact lens cleaning solution which can readily and simultaneously conduct hydrophilization and cleaning of proteinaceous stains of contact lenses and does not lower the detergency of a protease; and a method for simultaneously conducting hydrophilization and cleaning of proteinaceous stains of contact lenses by using the above cleaning solution. The objective cleaning solution comprises a protease in an amount effective in removing proteins deposited or adhered to contact lenses and gum arabic as a hydrophilizing component, and divalent metal ions in the gum arabic are removed or inactivated. Contact lenses are immersed in this solution to remove the proteins deposited or adhered to the lenses and, at the same time, to hydrophilize the lens surfaces.
(FR)La présente invention concerne une solution permettant d'effectuer instantanément et simultanément le retrait des taches et l'hydrophilisation de lentilles de contact sans pour autant abaisser la détergence d'une protéase. Le procédé consiste à effectuer instantanément et simultanément le retrait des taches et l'hydrophilisation des lentilles de contact au moyen de la susdite solution de nettoyage des lentilles qui comprend un mélange d'une protéase en quantité suffisante pour enlever les dépôts ou les adhérences protéiques tachant les lentilles de contact et d'une gomme arabique comme composant d'hydrophilisation et dans laquelle les cations métalliques bivalents ont été enlevés ou inactivés. On immerge les lentilles de contact dans ladite solution pour enlever les dépôts ou adhérences protéiques des surfaces des lentilles de contact qui sont en même temps hydrophilisées.
