An assembly of devices designed to provide visual function to a patient with vision loss due to retinal degeneration by detecting light, converting it into electrical signals, and relaying them to the retina for neural stimulation. It includes: 1) implantable components comprised of a subretinal chip (containing photodiodes, amplifier and stimulation electrodes) and a connected receiving coil; and 2) external components consisting of a transmitting coil designed to inductively power the implant transdermally, and a battery-powered hand-held control unit for providing power and adjusting implant settings.
