Abstract: An intraocular lens includes a optical body including a posterior concave rface with a first radius of curvature, a periphery and a central, axially aligned opening that enhances liquid circulation in the eye, with the ratio of the height of the optical body to the overall height of the lens being between about 0.25 to about 0.5; a positioning element connected to the optical body periphery and including a periphery and a posterior concave surface with a second radius of curvature greater than the first radius of curvature, a ratio of the first to second radii of curvature being between about 0.31 to about 0.

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.
