Abstract
A visual prosthesis in the form of a retinal implant, which is distinguished by the least possible space requirement inside the eye, is achieved by a visual prosthesis having an intraocular implant and an extraocular implant, which supplies the intraocular implant with energy and controls it. Virtually all the electronic components, which do not necessarily need to be accommodated with the intraocular implant inside the eye, can be arranged outside the eyeball, for example on the sclera. In this way, the space requirement of the stimulation system inside the eye is reduced and the operative intervention for implanting the stimulation system inside the eye is kept as small as possible. A bidirectional inductive interface between an extracorporeal part of the visual prosthesis and an intracorporeal part, including the intraocular and extraocular implants, via which a current supply and bidirectional data transmission can be carried out is provided.
