ABSTRACT:
Intraocular implants having optical lenses that are light, non-toxic, biocompatible, nonleachable in the presence of eye fluids and absorb at least 90% of the ultraviolet light in the 300-380 nm wavelength range but are transparent to most of the visible radiation. The intraocular implants will have a haptic for fixation in the posterior or anterior chamber of the eye. The optical lens has uniformly dispersed therein an ultraviolet light absorbing amount of 2-(hydroxy-lower alkylphenyl) benzotriazole which may be halogen substituted in the 4, 5, 6 or 7 positions.
