Implantierbares System zur Bestimmung des Akkommodationsbedarfes durch Messung der Augapfelorientierung unter Nutzung eines externen Magnetfelds

摘要

The present invention relates to an implantable system for determining the accommodation requirement in an artificial accommodation system by measuring the eyeball orientation using an external magnetic field, 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 spatial orientation of both eyeballs 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 measured physical control signals, d) at least one energy supply system (10), and e) one fixing system, wherein the system in each case has means for measuring a magnetic field in both eyes and provision is made for transfer means for mutual information exchange between the means.
