Abstract
Abstract An artificial eye lens, in which there is a lens body and three elastic supporting elements fixed on the lens body. Two supporting elements are shaped as rods, while one element is shaped as an angle-piece. The rod-shaped elements are arranged on the side diametrically opposite to the angle-piece. The aforesaid two rod-like elements make an angle 45 to 90 degrees with the plane passing through the vertex of the angle-piece and through the center of the lens body. All the supporting elements are so bent out as to lie parallel to the principal optical plane of the lens body.
