Title (EN) INTRAOCULAR LENS TUMBLING PROCESS USING COATED BEADS
(FR) PROCEDE DE POLISSAGE D'UNE LENTILLE INTRAOCULAIRE UTILISANT DES PERLES ENROBEES
Abstract:
(EN) A method of processing a soft or foldable lens includes a step of tumbling (grinding) the lens in a tumbling medium. The tumbling medium includes a mixture of glass beads coated with an abrasive material, alcohol and water. This process applies to single piece and multipiece soft lenses.
(FR) La présente invention se rapporte à un procédé de fabrication d'une lentille souple ou pliable durant lequel la lentille est travaillée au tonneau (polie) dans un tonneau à polir renfermant un mélange de perles de verre enrobées d'un matériau abrasif, de l'alcool et de l'eau. Ce procédé s'applique aux lentilles souples formées d'une ou de plusieurs pièces.
