1. An accommodative intraocular lens for insertion into the capsular bag of an eye, the accommodative intraocular lens comprising:
a first lens part including a light-transparent lens component having a distal surface of said light-transparent lens component and a proximal surface of said light-transparent lens component;
said first lens part further including a light-transparent first membrane arranged adjacent to said distal surface of said light-transparent lens component and delimiting a cavity together with said light-transparent lens component;
said first lens part defining an optical axis;
a second lens part configured to be detachably coupled to said first lens part, whereby the accommodative intraocular lens is able to be brought into a coupled state in which said second lens part is arranged on a distal side of said first lens part and configured to deform said first membrane by way of a longitudinal displacement of said second lens part parallel to said optical axis;
said second lens part including a first component, which forms a distal end of the second lens part and has an axial through hole in said first component, and a second component, which extends at least as far as the lens component in an axial direction with respect to said optical axis and defines an axial through hole in said second component, with said optical axis extending through said axial through hole in said first component and through said axial through hole in said second component;
said first component and said second component being securely connected to one another at their ends which, in said coupled state, are arranged outside in a radial direction with respect to the optical axis; and,
said first component and said second component being configured to be displaced toward one another in a case of increased stretching of the capsular bag and produce a restoring force as a result.
