Abstract: Ultraviolet light absorbing polymer compositions comprising copolymers of 2-Hydroxy-5-acrylyloxyphenyl-2H-benzotriazoles with one or more other monomers copolymerizable therewith, particularly acrylic monomers are useful in the manufacture of occular devices, particularly intraoccular lenses and contact lenses. Polymers of the disclosed benzotriazoles may be added to other organic materials to impart ultraviolet absorbing properties thereo.

Abstract: A method and apparatus for forming a round end on a small plastic filament which includes a die having a channel extending into one side with a hemispherical interior end and a bore extending into the other side and coaxially aligned with the channel and having a conic interior end. The tip of the conic section communicates with the hemispherical section. A relief recess is spaced from the periphery of the hemispherical section by a land portion. The peripheral edge of the land portion, which also forms the edge of the channel, may be formed into a knife edge. In the die the filament is cold-formed to provide a hemispherical section spaced apart from the distal end of the filament. Material displaced during the cold-forming process is deposited in a relief section extending peripherally about the channel.

Abstract: An artificial intraocular lens assembly adapted for placement within the anterior or posterior chamber of the eye and for permanent attachment to the iris through natural ingrowth of living tissue, is disclosed. The lens assembly comprises a light refracting lens body and at least one lens support member which includes a portion having a surface contoured for intimate contact with the iris. A plurality of apertures are provided in the portion of the lens support member. After initial surgical affixation of the lens assembly within the eye, tissue of the iris grows into and through the apertures thereby anchoring the lens assembly within the eye.

Abstract: An intraocular lens storage container assembly that permits a visual inspection of the diopter power and size of the lens without removal from the container is provided. A transparent outer housing permits the transmission of light without any substantial distortion. A support member is configured to fit within the transparent outer housing and has at least one transmitting area that also permits the transmission of light without substantial distortion. A retention configuration is provided on the support member for securing the intraocular lens on the support member and a lid member is capable of locking the intraocular lens into a set position.

Abstract: An artificial intraocular lens designed for mounting within the anterior chamber of a patient's eye is disclosed. A substantially circularly shaped lens body which is refractive to light is provided with a pair of loops and a stave. The stave which is made of an elastic material such as polypropylene is fixedly mounted into an aperture in the lens body. The stave is provided with a keeper member on one side of a free end, the keeper member pointing away from an adjacent loop which is mounted to the same hemicircular segment of the lens as the stave. The opposite side of the stave provides a continuous substantially planar surface from the lens body to the free end of the stave. The loops are inserted behind the iris of the eye, and a surgical incision is made in the iris to permit the stave to be lead therethrough. The stave is capable of being bent until its free end traverses the loop, and as the bending force is released the keeper member engages the loop thereby fixedly positioning the lens in the eye.
