Accommodative intraocular lens for insertion into the capsular bag of an eye, the intraocular lens having: - a first lens part, which has: - an optic, which is transparent to light and has an optical axis, a distal optic surface and a proximal optic surface, - a haptic firmly connected to the optic, - a flexible membrane, which is firmly connected to the haptic and/or the optic, is arranged adjacent to the distal optic surface, delimits a cavity together with the distal optic surface and is transparent to the light, and - a second lens part, which has a hollow cylinder with a distal end and a proximal end and which can be detachably coupled to the first lens part, whereby the intraocular lens is able to 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 way of a longitudinal displacement of the hollow cylinder parallel to the optical axis, wherein the first lens part has a plurality of bending elements, which are attached to the membrane outside the cavity and which contact a proximal end of the hollow cylinder in the coupling state, and the hollow cylinder has on its outer side an outer surface, which is an outer end of the hollow cylinder in the radial direction with respect to the axis of the hollow cylinder, wherein the hollow cylinder has a bearing surface, which is configured to be contacted by the capsular bag, is arranged adjacent to a proximal end of the outer surface and includes an angle of less than 180° with the outer surface. - a first lens part, which has: - an optic, which is transparent to light and has an optical axis, a distal optic surface and a proximal optic surface, - a haptic firmly connected to the optic, - a flexible membrane, which is firmly connected to the haptic and/or the optic, is arranged adjacent to the distal optic surface, delimits a cavity together with the distal optic surface and is transparent to the light, and - a second lens part, which has a hollow cylinder with a distal end and a proximal end and which can be detachably coupled to the first lens part, whereby the intraocular lens is able to 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 way of a longitudinal displacement of the hollow cylinder parallel to the optical axis, wherein the first lens part has a plurality of bending elements, which are attached to the membrane outside the cavity and which contact a proximal end of the hollow cylinder in the coupling state, and the hollow cylinder has on its outer side an outer surface, which is an outer end of the hollow cylinder in the radial direction with respect to the axis of the hollow cylinder, wherein the hollow cylinder has a bearing surface, which is configured to be contacted by the capsular bag, is arranged adjacent to a proximal end of the outer surface and includes an angle of less than 180° with the outer surface. - an optic, which is transparent to light and has an optical axis, a distal optic surface and a proximal optic surface, - a haptic firmly connected to the optic, - a flexible membrane, which is firmly connected to the haptic and/or the optic, is arranged adjacent to the distal optic surface, delimits a cavity together with the distal optic surface and is transparent to the light, and - a second lens part, which has a hollow cylinder with a distal end and a proximal end and which can be detachably coupled to the first lens part, whereby the intraocular lens is able to 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 way of a longitudinal displacement of the hollow cylinder parallel to the optical axis, wherein the first lens part has a plurality of bending elements, which are attached to the membrane outside the cavity and which contact a proximal end of the hollow cylinder in the coupling state, and the hollow cylinder has on its outer side an outer surface, which is an outer end of the hollow cylinder in the radial direction with respect to the axis of the hollow cylinder, wherein the hollow cylinder has a bearing surface, which is configured to be contacted by the capsular bag, is arranged adjacent to a proximal end of the outer surface and includes an angle of less than 180° with the outer surface.
