    摘要： An intraocular implant having an optic lens and haptic for fixation of said lens in the posterior or anterior chamber of the eye, said implant having thermal stability sufficient to render said implant autoclave sterilizable, said implant being chemically stable when sterilized with high energy radiation, said optical lens consisting essentially of a solid thermoplastic polymer which is substantially transparent to visible light, is biocompatible, has a glass transition temperature of at least 120° CV and is thermally stable at a temperature of at least 120° C, and has a notched Izod impact strength at about one-eighth inch thickness of about at least one footpound per inch, said thermoplastic polymer having repeating units of aromatic groups linked together by one or more of the following linkages: ether, ester, sulphone, carbonyl and imide.

    摘要： 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.
