Abstract
Abstract An artificial eye lens (1) comprises an optical lens (2) and three supporting elements one of which is shaped as a loop (3), while the two other elements are made as V-shaped legs (4). The loop (3) and the legs (4) are situated on the diametrically opposite sides of the lens (2). Each of the legs (4) is secured with one of its sides (5) on the anterior surface of the lens, is inclined towards the posterior lens surface so that the other side (7) of the leg is situated in the lens principal plane. The legs diverge along the lens (2) lateral surface, and the ends of the leg sides (5 and 7) face each other.
