Abstract[English]
The invention provides a method for producing coated silicone hydrogel contact lenses in a cost-effective manner. The method comprises obtaining a preformed silicone hydrogel contact lens comprising a bulk silicone hydrogel material that comprises repeating units of at least one carboxyl-containing vinylic monomer and at least one arylborono- cotnaining vinylic monomer, and heating the preformed silicone hydrogel contact lens in an aqueous coating solution comprising a water-soluble and thermally crosslinkable polymeric material having azetidinium or epoxide groups and a diol-containing hydrophilic polymer having 1,2- or 1,3-diol moieties to form a coated silicone hydrogel contact lens comprising a bulk silicone hydrogel material and a hydrogel coating that comprises a crosslinked polymeric material covalently attached onto the bulk silicone hydrogel material and a grafted diol-containinghydrophilic polymer covalently attached onto the bulk silicone hydrogel material and distributed in the crosslinked polymeric material.[French]
L'invention concerne un procédé de production économique de lentilles de contact en hydrogel de silicone revêtues. Le procédé consiste à obtenir une lentille de contact préformée en silicone hydrogel comprenant un matériau de silicone hydrogel en vrac qui comprend des unités répétitives d'au moins un monomère vinylique contenant un carboxyle et d'au moins un monomère vinylique au moins un monomère vinylique contenant de l'arylboron, et le chauffage de la lentille de contact préformée en silicone hydrogel dans une solution aqueuse de revêtement contenant un matériau polymère soluble dans l'eau et thermiquement réticulable présentant des groupes azetidinium ou époxyde et un polymère hydrophile contenant un diol avec des groupements 1,2- ou 1,3-diol pour constituer une lentille de contact en silicone hydrogel revêtue contenant un matériau silicone hydrogel en vrac et un revêtement hydrogel contenant un matériau polymère réticulé fixé de manière covalente sur le matériau silicone hydrogel en vrac et un revêtement gravé qui comprend un matériau polymère réticulé fixé de manière covalente sur le matériau silicone hydrogel en vrac,
