Abstract: Described is an accommodating intraocular lens with a bi-convex, bi-aspheric, smooth surfaced optic held inside an anterior annulus via tabs. A second larger diameter annulus is positioned posteriorly and connects via a sloped surface to where the annuluses are at a maximum separation when viewing NEAR objects and minimum separation in the FAR position. The sloped surface is cut into ribbons, tabs and/or other annuluses without pushing the surfaces into the capsule when implanted; therefore, only the anterior and posterior annuluses have a force component against the capsule. The proximal edge of the anterior annulus is anterior to the apex of the anterior surface of the optic. The anterior capsule resting on the annulus leaves space for hydration of the capsule and reduces potential warpage of the optic. The annulus edge is designed to scrape posterior capsular opacification from the capsule.

Abstract: An ossicular prosthesis has a head plate as a first fastening element, a second fastening element for the mechanical connection to the ossicular chain, or to the inner ear, and a connecting element. The head plate has a central coupling region and radially outward extending bridging elements which are connected to the coupling region via a radially inner end region and each transition into an outer free end section. The bridging elements are connected to the coupling region so that they fold together upon introduction of a force component parallel to the longitudinal axis, wherein their end sections are pivoted radially closer to the longitudinal axis and thereby also execute an axial movement. The bridging elements, without this force, extend from the coupling region at a predefined, fixed angle. The prosthesis can be inserted into the middle ear of the patient more easily and through a much smaller artificial opening.
