  • Patent number: 5258025
    Abstract: An optical body, a positioning element, and a supporting element are shaped as an integral unit and have the same radius of curvature that provides for full adherence of the integral unit to an intact natural lens. The distance between the diametrically opposite portions of the supporting element is at least equal to the distance between Zinn's zonules on which the corrective lens rests.
