The present invention relates to an intracorneal lens (), comprising a circular main body having a convex front surface and a convex rear surface, characterized in that the convex front surface has a single uniform radius of curvature (Rcv) and the concave rear surface has a radius of curvature (Rcci). The radius of curvature (Rcci) of the concave rear surface is greater than the average radius of the cornea by 0.1 mm to 2 mm, preferably 0.2 to 1.5 mm, in particular preferably 0.5 to 1 mm. The present invention further relates to a kit, comprising a storage unit () and a pre-load unit (P) inside the storage unit (). The storage unit () is made of a watertight material and can be closed watertight by means of a plug (). The pre-load unit (P) is fitted with the intracorneal lens according to the invention.

Intracorneal lens

A pre-load unit, for inserting a lens into the eye of a human or animal, includes a housing, a lens-receiving part arranged on or in the housing, having a section that protrudes from the housing, and two separate leaf-like units which, at least at their ends directed away from the housing, are in releasable contact with each other and form a chamber of storing an optical lens. A slide which is arranged movably in the interior of the housing can be moved between the leaf-like units of the lens-receiving unit. The pre-load unit may be combined with a grip piece, wherein the pre-load unit and the grip piece are connected to each other in such a way that the pre-load unit can be moved inside the grip piece.

A method of finding the position of a mechanical axis running in the longitudinal direction through a limb that is rotatably supported by its first end in a center of rotation that is not fixed and is not accessible for the mechanical determination of coordinates, by means of an optical coordinate-measurement device with an indicator to detect measurement-point coordinates in one rotational position of the limb such that, for each rotational position, a multi-point indicator rigidly attached near the second end of the limb signals several measurement-point coordinates, and, from the sets of measurement-point coordinates detected in a plurality of rotational positions, at least one group is selected that can be assigned to the same site of the center of rotation, and the measurement-point-coordinate sets assigned to this site of the center of rotation are used to calculate the mechanical axis.

A knee-joint prosthesis with a tibial part having a flat tibial bearing surface, with a bearing body that can be shifted thereon in the anterior-posterior direction and includes two concave bearing shells within which a femoral joint part can be movably seated, and with a rotational guide that permits rotation of the bearing body on the tibial bearing surface about an axis of rotation perpendicular to said surface. The rotation guide includes a steering rod that is seated at the bearing body so as to be pivotable relative thereto and at the tibial part is guided in the medial/lateral direction and/or rotationally guided.

Knee-joint endoprosthesis

A device for localizing and executing resection cuts on the femur ( ) for preparing an implantation of a total endoprosthetic knee joint is provided. The device includes a reference device ( ) adapted to be releasably attachable to the femur ( ) in the distal area of the femur ( ). Alignment of the reference device ( ) relative to the femur ( ) should be accurately positionable. An adjustment device ( ) is connected to the reference device ( ). The adjustment device ( ) is movable relative to the reference device ( ) and is provided with a linearly movable base part ( ) for the attachment of an instrument ( ). A first drive device ( ) linearly moves the adjustment device ( ) relative to the reference device ( ) in the direction ( ) of a first axis (X) of a system of coordinates (X, Y, Z). A second drive device ( ) linearly moves the base part ( ) in the direction ( ) of another, second axis (Y) of said system of coordinates (X, Y, Z). Both the first and second drive devices ( ) include a motor drive.
