The invention provides an ocular socket prosthesis comprising a hydrogel consisting essentially of a biocompatible hydrophilic polymer onto which tissues can be directly sutured. Preferably the prosthesis comprises the polymer both in its homogeneous gel form and in its sponge form, and the two forms are chemically joined at their interface via an interpenetrating polymer network (IPN). However, it is also contemplated that the prosthesis of the invention may be made predominantly or entirely from the sponge form of the polymer. Methods of production of the prosthesis of the invention and of surgical implantation are also disclosed and claimed.
L'invention porte sur une emboîture de prothèse oculaire comprenant un hydrogel constitué essentiellement d'un polymère hydrophile biocompatible sur lequel des tissus peuvent être directement cousus. De préférence, la prothèse comprend ladite polymère tant sous forme de gel que sous sa forme de mousse, les deux formes étant liées chimiquement au niveau de leur interface, par l'intermédiaire d'un alliage IPN. Toutefois, suivant le procédé de l'invention, la prothèse peut être également fabriquée essentiellement ou entièrement en utilisant le polymère sous sa forme de mousse. L'invention porte également sur des procédés de fabrication et d'implantation chirurgicale de la prothèse et sur des revendications les concernant.
