RETINAL PROSTHESIS
First Claim
1. Apparatus, comprising:
- an external device, comprising;
a mount, configured to be placed in front of an eye of a subject;
a laser coupled to the mount and configured to emit toward the eye radiation that is outside of 380-750 nm; and
a partially-transparent mirror coupled to the mount; and
an intraocular device configured to be implanted entirely in the subject'"'"'s eye, the intraocular device comprising;
an energy receiver, configured to receive the radiation from the laser and to generate a voltage drop in response thereto;
a plurality of stimulating electrodes;
a plurality of photosensors, each photosensor configured to detect photons and to generate a signal in response thereto; and
driving circuitry, coupled to the energy receiver and to the photosensors, and configured to receive the signals from the photosensors and to utilize the voltage drop to drive the electrodes to apply currents to a retina of the eye in response to the signals from the photosensors.

Abstract
Apparatus is provided, including an external device, including a mount, which is placed in front of an eye of a subject. A laser is coupled to the mount and configured to emit toward the eye radiation that is outside of 380-750 nm. A partially-transparent mirror is coupled to the mount. An intraocular device is implanted entirely in the subject'"'"'s eye, and includes a plurality of stimulating electrodes, and an energy receiver, which receives the radiation from the laser and generates a voltage drop in response thereto. A plurality of photosensors detect photons and generate a signal in response thereto. Driving circuitry is coupled to the energy receiver and to the photosensors, and receives the signals from the photosensors and utilizes the voltage drop to drive the electrodes to apply currents to the retina in response to the signals from the photosensors. Other embodiments are also described.
