Abstract

------09/08/2022------(OCR) Design of support structure for a 6.0 mm diameter intraocular lens. The lens is convex on both sides and connected to the lens body. The support legs are designed to be slightly thinner than the lens body to leave a cutting edge only on the posterior surface of the lens, preventing cell migration within the lens capsule, which is a problem causing lens opacity after lens replacement surgery. The support legs are long, curved, and symmetrically arranged in a counterclockwise direction. The total diameter of the legs is 13.0 mm. They incorporate 5 wavy grooves to support and distribute pressure, providing flexibility and a wide contact angle that conforms to the lens capsule. The rounded ends provide stability, keeping the lens centered, preventing rotation, and avoiding warping along the central axis of displacement when inside the lens capsule. ------------ ------15/07/2021------(OCR) Design of support structure for a 6.0 mm diameter intraocular lens.

Summary of the Invention. The design of a haptic support structure for an artificial intraocular lens with a diameter of 6.0 millimeters, consisting of two convex lenses connected to the lens body, features legs designed to be slightly thinner than the lens body. This leaves a cut-off edge only on the posterior surface of the lens, preventing cell migration within the lens capsule, which is a problem causing lens opacity after lens replacement surgery. The supporting legs consist of two elongated, curved legs arranged symmetrically in a counterclockwise direction. The total diameter of each leg is 13.0 millimeters. They feature five ribbed grooves to support and distribute pressure, providing flexibility and a wide contact angle that conforms to the lens capsule. The rounded ends provide stability, keeping the lens centered, preventing rotation and warping along the central axis of the lens when inside the lens capsule.
