IMPLANTABLE SYSTEM FOR DETERMINING THE ACCOMMODATION REQUIREMENT BY MEASURING THE EYEBALL ORIENTATION USING AN EXTERNAL MAGNETIC FIELD

摘要

The invention relates to an implantable system for determining the accommodation requirement in an artifical accommodation system by measuring the eyeball orientation using an external magnetic field, said system comprising a) at least one optical system (3); b) at least one information detection system (8) which does not come into contact with the ciliary muscle and comprises means for detecting a spatial orientation of both eyeballs as a physical control signal for the accommodation requirement; c) at least one information processing system (9) for producing a corrective signal for the optical system (3) from the detected physical control signals; d) at least one energy supply system (10); and e) a fixing system, said system comprising respective means for measuring a magnetic field in both eyes, and transmission elements are provided for the mutual information exchange between said means.
