ABSTRACT:
An object of the invention is to provide an intraocular implant-type vision stimulating unit which is capable of outputting a bipolar pulse signal in a simple constitution, and is highly sensitive, compact, and low power consumptive.In the invention, an intraocular implant-type vision stimulating unit for artificially generating the vision or a portion of the vision includes: a photoelectric conversion circuit for converting incoming light into an electrical signal; a pulse conversion circuit for converting the electrical signal outputted from the photoelectric conversion circuit into an electric pulse signal of a frequency corresponding to a magnitude thereof, and for outputting the same; a waveform shaping circuit for converting the pulse signal outputted from the pulse conversion circuit into a bipolar pulse signal, and for outputting the same; a power supply circuit for supplying electric power to each of the circuits, wherein the bipolar pulse signal is imparted to a retinal region through an electrode.
