The current invention provides a method of forming a foldable intraocular having a high refractive index from a copolymer comprising a first monomer comprising an aryl acrylate or an aryl methacrylate; a second monomer comprising an aromatic ring comprising a substituent having one ethylenic unsaturation, provided that the second monomer is not an aryl acryate or aryl methacrylate, and a third monomer comprising one ethylenic unsaturation that, if polymerized into a homopolymer, forms a high water content hydrogel; and, optionally, a cross-linking agent.
La présente invention concerne un procédé de formation d'un intraoculaire pliable doté d'un indice de réfraction élevé à partir d'un copolymère comportant un premier monomère comprenant un acrylate d'aryle ou un méthacrylate d'aryle, un second monomère comprenant un noyau aromatique incluant un substituant presentant une insaturation éthylénique, à la condition que le second monomère ne soit pas un acrylate d'aryle ou un méthacrylate d'aryle, et un troisième monomère présentant une insaturation éthylénique qui, s'il est polymérisé en un homo-polymère, forme un hydrogel à teneur élevée en eau, et, facultativement, un agent réticulant.
