The present invention is ultraviolet light absorbing biocampatible polymer containing the copolymerization product of a mixture of hydrophobic and hydrophilic acrylic and/or allelic monomers, graft-polymerized with telo- collagen, where the hydrophobic monomers include at least one ultraviolet light absorbing hydrophobic acrylic or allelic monomer. The present material is useful in the production of deformable lenses, for example, intraocular lenses, refractive intraocular contact lenses, and standard contact lenses useful, for example, for correcting aphekia, myopia and hypermetropia.
L'invention concerne un polymère biocompatible absorbant la lumière ultraviolette et contenant le produit de copolymérisation d'un mélange de monomères, soit acryliques, soit alléliques, hydrophobes et hydrophiles, polymérisés avec greffage avec un télo-collagène, les monomères hydrophobes comprenant au moins un monomère acrylique ou allélique hydrophobe absorbant la lumière ultraviolette. Ce matériau est utile pour fabriquer des lentilles déformables, par exemple, des lentilles intraoculaires, des lentilles de contact intraoculaires à réfraction et les lentilles de contact standard servant, par exemple, à corriger l'aphakie, la myopie et l'hypermétropie.
