Patent ID: 8150526

Claim:
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 minor 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; wherein the external device comprises a sensor coupled to the mount, configured to detect when an eyelid of the subject is closed, and wherein the laser is configured to discontinue emission of the radiation toward the subject's eye when the eyelid is closed.
