Biocompatible polymers useful for making intraocular lenses are provided. The biocompatible polymers are generally composed of one or more acrylate monomers, crosslinked with at least one diacrylate ester and may include one or more additional components such as ultraviolet light and/or blue-violet light absorbing dyes. The posterior chamber IOLs made using the biocompatible polymers disclosed herein are suitable for placement in phakic or aphakic eyes and are intended for refractive correction including myopia, hyperopia, presbyopia, astigmatisms and for implantation after removal of the natural crystalline lens as warranted by medical conditions such as cataracts.

Cette invention concerne des polymères biocompatibles utilisables dans la fabrication de cristallins artificiels. Ces polymères biocompatibles se composent généralement d'un ou de plusieurs monomères d'acrylate, réticulés avec au moins un ester de diacrylate, et ils peuvent contenir un ou plusieurs composants additionnels, tels que des colorants absorbant la lumière ultraviolette et/ou la lumière bleue-violette. Les cristallins artificiels de chambre postérieure fabriqués au moyen de ces polymères biocompatibles sont appropriés pour être placés dans des yeux phatiques ou aphatiques et ils sont destinés à la correction réfractive, par exemple de la myopie, de l'hypermétropie, de la presbytie et des astigmatismes, ainsi qu'à l'implantation après retrait du cristallin naturel justifié pour des raisons médicales, comme dans le cas des cataractes.
