Accommodating intra-ocular lens system
First Claim
1. A system for causing a change in the shape of a compressible, accommodating intra-ocular lens (IOL) of a subject, the system comprising:
- a) an IOL complex comprising a compressible, accommodating IOL;
b) at least one sensor for detecting a signal from the subject'"'"'s ciliary muscle;
c) a signal processor for receiving and processing the ciliary muscle signal to generate a corresponding electrical signal;
d) a transmitter for transmitting the electrical signal;
ande) at least one micromotor for receiving the transmitted electrical signal and causing a change in shape of the IOL, the IOL complex further comprising an external lens membrane and an annular support ring system for providing a means to cause a change in shape of the IOL, wherein the annular support ring system comprises two concentric rings including an outer annular ring and an inner annular ring, the outer annular ring being rigid for resisting compressive forces of the native capsular bag, the inner annular ring encircling the external lens membrane and providing a foundation for the at least one micromotor to cause a change in shape of the IOL; and
f) a ciliary sulcus ring adapted for implantation in the ciliary sulcus of the subject and adapted to be positioned around the IOL complex.

Abstract
An implantable, compressible, accommodating intra-ocular lens (IOL) coupled to at least one sensor which detects a signal created by the ciliary muscle. A ciliary sulcus ring can house the at least one sensor, and the sensor can include miniaturized electrodes (ciliary muscle probes) for implanting into the ciliary muscle of the subject. A potentiometer/microcomputer can modulate the ciliary muscle signal detected by the sensor(s) into an electrical signal, and a transmitter sends this electrical signal to a micromotor, which causes compression of the IOL via an annular support ring system, causing a change in the IOL shape. The IOL can be part of an IOL complex including a compressible, accommodating IOL, an external lens membrane, and an annular support ring system. The annular support ring system provides a foundation for the micromotor to compress the IOL.
