Title (EN) SURFACE TREATMENT OF RIGID GAS PERMEABLE CONTACT LENSES
(FR) TRAITEMENT DE SURFACE POUR LENTILLES DE CONTACT RIGIDES PERMEABLES AUX GAZ
Abstract: front page image
(EN)The present invention provides an optically clear, hydrophilic coating upon the surface of a rigid gas permeable contact lens by treating the surface of the contact lens with a strong caustic agent and subsequently sonicating the lens in an aqueous solution containing a surface-protective agent.
