Abstract:
1. A retinal prosthesis, comprising: an RF coil adapted to be attached to the outside of and moving with an eye to receive power from an external power source; electronic circuitry adapted to be attached to and moving with the eye and electrically connected to the RF coil; a light sensitive array electrically connected to the electronic circuitry and adapted to be located within the eye for receiving incident light and for generating an electrical signal in response to the incident light; and a stimulating array adapted for abutting a retina of the eye and electrically connected to the electronic circuitry to stimulate retinal tissue in response to the electrical signal from the light sensitive array, further comprising wireless control means for specifying, from outside the body of a patient, a transformation in response to the patient's reported perceptions by which electrical signals from the light-sensitive array are transformed into a set of electrical patterns to the stimulating array to influence visual function.
