Accommodative intraocular lens

The invention relates to an accommodative intraocular lens for implantation in an eye within a natural capsular bag in the eye, said capsular bag being attached at the circumference thereof to a ciliary muscle of the eye by means of zonular fibres. The intraocular lens has: - a first lens part, which has: an optical body which is transparent to light and has an optical axis, a front optical body surface and a rear optical body surface; haptics which are connected permanently to the optical body and are designed to come into engagement with the capsular bag in order to arrange the optical body centrally in the capsular bag; a flexible membrane which is connected permanently to the haptics or the optical body and has a front membrane surface and a rear membrane surface, wherein the membrane is arranged adjacent to the front optical body surface, the membrane has a centre axis which runs congruently or parallel to the optical axis, the rear membrane surface has a radius of curvature, the membrane is transparent to light; and - a second lens part, which has a hollow cylinder which can be coupled detachably to the membrane, wherein the hollow cylinder can be positioned with a proximal end on the front membrane surface of the first lens part such that, by means of a compressive force which acts on a distal end of the hollow cylinder parallel to the optical axis and can be generated by a movement of the ciliary muscle of the eye, 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.
