ELECTRICAL AMPLIFICATION OF PHYSIOLOGIC SIGNALS FOR ACCOMMODATIVE IOL CONTROL

摘要

A control system (100) for an accommodative intraocular lens includes a sensing circuit (110) for sensing a signal that controls a ciliary muscle of an eye and an amplifier circuit (130) for amplifying the sensed signal. The output of the amplifier circuit is used to control an accommodative IOL. At least one electrode located in the vicinity of cranial nerve III, the ciliary ganglion, or the ciliary muscles is used to receive the signal that controls the ciliary muscles. A filter may also be included.
