Acrylic, high refractive index ophthalmic device materials comprising an aryl acrylic monomer, a first stage polymerization initiator and a second stage cross-linking agent are prepared in a two-stage method. The monomers used to form the ophthalmic device materials do not contain cross-linking agents having more than one unsaturated bond. In the first stage of the method, the materials are polymerized. In the second stage, the materials are cross-linked by exposure to heat.

On prépare à l'aide d'un procédé en deux étapes des matériaux acryliques pour dispositifs ophtalmiques à indice de réfraction élevé comprenant un monomère acrylique aryle, un initiateur de polymérisation de première étape et un agent de réticulation de deuxième étape. Les monomères utilisés pour former les matériaux pour dispositifs ophtalmiques ne contiennent pas d'agent de réticulation ayant plus d'une liaison non saturée. Dans la première étape du procédé, les matériaux sont polymérisés, et dans la deuxième étape, les matériaux sont réticulés par exposition à la chaleur.
