CA 2588538

Polymerizable light absorbing azo dyes are disclosed useful as monomers in the formation of devices such as, but no limited to ocular lenses. Specifically, intraocular lenses (IOL) are disclosed wherein one or more of the light absorbing dye is covalently bonded to other structural polymers though ethylene unsaturated groups. The resulting IOLs possess light absorbing properties without significant amounts of free (un-bound) azo dye molecules present in the final structural polymer matrix.

L'invention concerne des colorants azoïques photo-absorbants polymérisables, utiles en tant que monomères dans la formation de dispositifs tels que, notamment, des lentilles oculaires. De manière spécifique, cette invention concerne des lentilles intraoculaires (LIO), dans lesquelles un ou plusieurs colorants photo-absorbants est (sont) lié(s) par covalence à d'autres polymères structurels malgré des groupes éthyléniquement insaturés. Les LIO obtenues possèdent des propriétés photo-absorbantes sans importantes quantités de molécules de colorant azoïque libres (non liées) présentes dans la matrice polymérique structurelle finale.
