Abstract

To recover visual sensation of blind patients, we have fabricated a fully implantable retinal prosthesis chip that includes photodetector and stimulus current generator. For the first time, we successfully implanted the retinal prosthesis chip bonded on the flexible cable with stimulus electrode array into a rabbit eyeball. Moreover, we recorded and analyzed electrically evoked potential (EEP) elicited from a rabbit brain by current stimulation to retina.
