Patent Images
1. Apparatus and for stimulating vision, the apparatus configured to receive stimulation signals, the apparatus comprising:
- A. a flexible substrate configured for implantation on a retina, the substrate comprising a central member and at least one wing extending along at least a portion of a peripheral edge of the central member and defining a gap therebetween; and
B. an array of retina stimulators disposed within the substrate and configured to stimulate the retina in response to receipt of the stimulation signals.

Abstract
A wide-filed retinal prosthesis enables an increased field of vision with a relatively small scleral incision. The retinal prosthesis includes a flexible substrate comprising a central member and at least one wing, with an array of electrodes disposed therein that are configured to stimulate the central and peripheral nerves of the retina.
