ARTIFICIAL EYE LENS

The invention relates to an eye lens (1) with a haptic element (20) and an optical element (10). The optical element (10) has two optical surfaces (12, 14) and can be moved relative to the haptic element (20) by overcoming static friction. The aim of the invention is to provide a solution which allows vision correction, without invasive surgical intervention, after the implantation of the eye lens (1). This is achieved by an eye lens (1) which has a compartment (30) that comprises an outlet channel (35) and can receive a liquid (50). The eye lens (1) is designed to allow energy to be input into the liquid (50) received in the compartment (30). The outlet channel (35) is designed such that upon inputting energy into the received liquid (50), a discharge out of the compartment (30) occurs through the outlet channel (35) such that a movement of the optical element (10) relative to the haptic element (20) is produced. The aim of the invention is additionally achieved by a planning unit (P) for a correcting device (100) comprising an energy device (110), a focusing device (120), and a control unit (130) that generates control data, by means of which an energy input for moving the optical element (10) relative to the haptic element (20) is facilitated. The aim of the invention is additionally achieved by a corresponding correcting device (100), a planning method, and a correcting method.
