A wettable silicone hydrogel made by including a high molecular weight hydrophilic polymer into the silicone hydrogel monomer mix is presented. The hydrophilic polymer is entrapped in the hydrogel with little or no covalent bonding between it and the hydrogel matrix.
La présente invention concerne un hydrogel mouillable, à base de silicone, obtenu par l'introduction d'un polymère hydrophile de poids moléculaire élevé dans le mélange monomère de l'hydrogel au silicone. Ce polymère hydrophile est emprisonné dans l'hydrogel en étant faiblement ou nullement lié par covalence avec la matrice dudit hydrogel.
