Retinal prostheses is a promising technique to restore eyesight from ophthalmic diseases, such as age-related macular degeneration (AMD) and retinitis pigmentosa (RP), by replacing damaged living photoreceptor cells with electronic photo devices and photo-sensing circuits. Some conventional retinal prostheses require external cameras, and the eyeball direction is different from the view direction, although some proposals are presented.
The outstanding advantages of Retinal Prosthesis are: thin-film photo-transistors are integrated to remove the external camera. To make the eyeball direction and view direction the same, a transparent substrate is employed to achieve the epiretinal implantation smartly and wireless power transfer is adopted to remove the wired connection between inside and outside of the body. It should also ensure the QOL. In this paper, the epiretinal implantation technique of the retinal prosthesis using the thin-film devices on the transparent substrate and wireless power transfer is designed. Because the transparent substrate is employed so that the illuminating light can be irradiated from one direction of the retinal prosthesis and the stimulating signal can be sent to the other direction, epiretinal implantation technique can be smartly achieved.
