Abstract

An accommodative intraocular lens for implantation in an eye within a natural capsular bag includes a first lens part with an optical body transparent to light and defining an optical axis, front and rear optical body surfaces, haptics connected permanently to the optical body and designed to come into engagement with the capsular bag, a flexible membrane connected permanently to the haptics or the optical body, the membrane having a center axis which runs congruently or parallel to the optical axis and is transparent to light, and a second lens part with a hollow cylinder which can be positioned with a proximal end on the front membrane surface of the first lens part such that the hollow cylinder and the membrane can be displaced along the optical axis towards the front optical body surface and thus the rear membrane surface undergoes a change in the radius of curvature thereof.
