Abstract: The invention relates to a microcontact structure for epiretinal or cortical contacting of nerve tissue for a vision prosthesis in mammals or human beings. Due to the fact that the thickness of the surface of the microcontacts (2) is not constant along the surface of the microcontact structure, the resolution can be adapted to physiological requirements.
Abstract: A retinal implant has at least one functional unit positioned internally inside an eye and at least one functional unit positioned externally outside the eye and at least one functional unit positioned outside the eye, which are separably connected to one another via a signal path in a manner designed for signal or data transmission. The patient's residual vision which may still remain is preserved because the signal path extends through the sclera of the eye and does not incorporate the anterior eye section.
