Built-in-eye- eyesight stimulating apparatus
First Claim
1. An intraocular implant-type vision stimulating unit for artificially generating the vision or a portion of the vision, comprising:
- a photoelectric conversion circuit which converts incoming light into an electrical signal;
a pulse conversion circuit which converts the electrical signal outputted from the photoelectric conversion circuit into an electric pulse signal of a frequency corresponding to a magnitude of the electrical signal, and outputs the electric pulse signal;
a waveform shaping circuit which converts the pulse signal outputted from the pulse conversion circuit into a bipolar pulse signal, and outputs the bipolar pulse signal;
a power supply circuit which supplies electric power to each of the circuits, wherein the bipolar pulse signal is imparted to a retinal region through an electrode.
