Abstract

An accommodative intraocular lens includes a first lens part, a haptic, and a flexible membrane. The flexible membrane is arranged adjacent to a distal optical body surface, delimits a cavity together with the distal optical body surface and is transparent to light. A second lens part has a hollow cylinder coupled releasably to the first lens part, as a result of which the intraocular lens can be brought into a coupling state in which the second lens part is arranged on a distal side of the first lens part and the hollow cylinder is configured to deform the membrane by a longitudinal displacement of the hollow cylinder parallel to the optical axis. The hollow cylinder has on its exterior an outer face and a bearing face arranged adjacent to a proximal end of the outer face and encloses, with the outer face, an angle of less than 180°.
