| 摘要 |
The present invention relates to an implantable system for determining the accommodation requirement in an artificial accommodation system by optical measurement of the pupil diameter and the surrounding luminance, comprising a) at least one optical system (3), b) at least one data acquisition system (8) which does not contact the ciliary muscle and has means for measuring a diameter of the pupil and luminance around at least one eye as a physical control signal for the accommodation requirement, c) at least one data processing system (9) for generating an actuating signal for the optical system (3) from the detected physical control signals or for the purpose of switching to the stand-by mode, d) at least one energy supply system (10), and e) at least one fixing system, wherein the system has one sensor (3) or a plurality of sensors with sensor elements for measuring the pupil diameter and the surrounding luminance.
