Abstract: Intra-ocular implant lens (11) in which is embedded a transparent, tinted plastic disc (15).

Abstract: Device for perforating the lens capsule front wall in the eye of living beings for removing a part of the capsule wall and producing an opening through which the lens capsule contents can be removed. A tube is arranged on a hand piece, in which a wire provided with a point on its free end is held, said wire being connected to a drive motor putting the wire in axially reciprocating motion.

Abstract: A one-piece implantation lens is provided as a replacement for a natural lens which has been surgically, particularly extracapsularly, removed from the eye of living beings of a higher order and which has, on the one hand, a central lens body designed as a collective lens and, on the other hand, holding means in the form of thin-walled, flat support elements arranged peripherally on the lens body, radially extending outwardly from the lens body and fixing it in place, with the outer edge of the support elements lying on a circular arc around the center of the lens body; and which consists of a homogenous, crystal-clear, high-temperature resistant plastic, preferably vulcanized silicone, with a specific gravity of between 1.01 and 1.08, preferably approximately 1.02, wherein at least one of the two surfaces of the central lens body is in the form of the optically effective surface of a Fresnel lens.

Abstract: A posterior chamber implant lens as a replacement for the natural lens surgically removed, in particular extracapsularly, from the eye of a living being of a higher order, with a central lens body and holding means arranged on the lens body, extending radially outwards from the periphery of the body and fixing it in its position, of a homogeneous, clear, vulcanized silicone rubber, wherein(a) the lens body is formed as a convex lens, wherein the rear surface facing the rear wall of the lens capsule has a greater, preferably much greater curvature than the front surface facing the iris,(b) a basically radially outwardly extending, thin-walled support which encircles the center point of the lens body and has a diameter of between approx. 9.0 and approx. 12.0 mm, preferably of about 10.0 to 11.0 mm(c) there are several openings in the support element distributed over the element, preferably in the form of round holes(d) the support element has a material thickness of between approx. 0.15 mm and 0.

Abstract: An artificial implant lens for the eye of a living being has a central lens body and front and rear annular discs surrounding the lens body. The annular discs overlap the iris and secure the lens to the iris.
