Title (EN) SURFACE TREATMENT OF NON-PLASMA TREATED SILICONE HYDROGEL CONTACT LENSES
(FR) TRAITEMENT DE SURFACE DE LENTILLES DE CONTACT A BASE D'HYDROGEL DE SILICONE, NON TRAITEES AU PLASMA
Abstract: front page image
(EN) The present invention provides an optically clear, hydrophilic coating upon the surface of a non-plasma treated hydrophobic hydrogel lens by heating the lens in an aqueous solution containing a surface-protective agent. Alternately, the non-plasma treated hydrophobic hydrogel lens may be subjected to ultrasonication while immersed in an aqueous solution containing a surface-protective agent.
(FR) La présente invention concerne un revêtement hydrophile, optiquement clair, sur la surface d'une lentille à base d'hydrogel hydrophobe non traitée au plasma, obtenu par chauffage de la lentille dans une solution aqueuse contenant un agent de protection de surface. Selon un autre mode de réalisation, la lentille à base d'hydrogel hydrophobe non traitée au plasma peut être soumise aux ultrasons lorsqu'elle est immergée dans une solution aqueuse contenant un agent de protection de surface.
