| titleOfInvention | Posterior chamber lens |
| abstract | A rear chamber lens (10) consists of a plano-convex polyethylmethacrylate (PMMA) lens (12) and two flexible, smooth, curved, single-filament handles (14, 16) fixed and extending from the optics (12 ). Each of the handles (14, 16), also made of PMMA, makes an angle of 10o forwards from the flat surface (18) of the optics (12). The optic (12) is reversed so that the convex surface (22) is posterior and is provided with positioning orifices (44, 46). The handles with decreasing radius (14, 16) and the optics (12) in PMMA make it possible to obtain handles (14, 16) and a lens (10) flexible, light and with thin edges. The angle of the PMMA handles and the planoconvex design of the optics arch the lens away from the iris. The positioning holes (44, 46) are located in the midday and six o'clock positions and have a desired predetermined size. A second embodiment of the PMMA lens (100) includes PMMA handles (104, 106) which are substantially parallel to the planar surface (108) of the lens (100). A third embodiment of the PMMA lens (200) includes PMMA handles (204, 206) which make an angle of 10o forward from the convex surface (212) of the optics (202). A fourth embodiment of the PMMA lens (300) includes closed PMMA handles (304, 306) which can form an angle relative to the surface of the lens (300). A small handle (48) can be provided at the end of each open handle (14) of decreasing radius. The handle (50) can be reversed or fold up and attach to the optics (12). A geometric member (52) can be positioned at one end of each handle. One handle can be opened and another handle can be closed. The circular positioning of the handle can be carried out by the junction between one of the handles and the optics (12). The handles fixed to the optics (12) can be identical with each other or take different geometric shapes. |
