Abstract
An implantable system for determining the accommodation requirement in an artificial accommodation system by optical measurement of the pupil diameter and the surrounding luminance, including at least one optical system, at least one data acquisition system that does not contact the ciliary muscle and measures a diameter of the pupil and luminance around at least one eye as a physical control signal for the accommodation requirement, at least one data processing system for generating an actuating signal for the optical system from the detected physical control signals or for the purpose of switching to the standby mode, at least one energy supply system, and at least one fixing system. The system has one sensor or a plurality of sensors with sensor elements for measuring the pupil diameter and the surrounding luminance.
