Title (EN) HYDROGEL CONTACT LENSES
(FR) LENTILLES DE CONTACT HYDROGEL
Abstract:
(EN) The present invention relates to a hydrogel contact lens having improved wettability, and particularly to a hydrogel contact lens of a complex membrane having an IPN (interpenetrating polymer network) intra structure, which is prepared by crosslinking composition for a contact lens comprising, as a main ingredient, an acryl monomer and an oligosaccharide and optionally a silicone compound. Due to the presence of an oligosaccharide in a contact lens herein, tensile strength and wettability can be maximized to provide a superior wearing feeling and maintain wettability even after a long-term storage in a care solution such as a washing solution, a storage solution and a protein-removing solution.
(FR) La présente invention concerne une lentille de contact hydrogel ayant une aptitude au mouillage améliorée et, en particulier, une lentille de contact hydrogel d'une membrane complexe, ayant une structure interne de réseau polymère interpénétrant (IPN), qui est préparée par la réticulation d'une composition pour une lentille de contact comportant, en tant qu'ingrédient principal, un monomère acrylique et un oligosaccharide et, facultativement, un composé de silicone. En raison de la présence d'un oligosaccharide dans une lentille de contact, la résistance à la rupture et l'aptitude au mouillage peuvent être maximisées afin de donner une sensation de confort d'utilisation supérieure et de conserver l'aptitude au mouillage même après un stockage à long terme dans une solution de soin, telle qu'une solution de lavage, une solution de stockage et une solution éliminant les protéines.
