EXTRAOCULAR EPIRETINAL IMPLANT

摘要

The aim of the invention is to provide a visual prosthesis in the form of a retinal implant which requires as little space as possible in the interior of the eye. This aim is achieved according to the present invention by a visual prosthesis that comprises an intraocular implant and an extraocular implant supplying the intraocular implant with power and controlling it. The inventive visual prosthesis is advantageous in that virtually all electronic components that do not necessarily have to be accommodated together with the intraocular implant in the interior of the eye can be accommodated outside the eyeball, for example on the sclera. Accordingly, the space required in the interior of the eye for the simulation system can be reduced and surgery for implanting the stimulation system in the interior of the eye can be kept minimally invasive. The invention also relates to a bi-directional inductive interface between an extracorporeal part of the visual prosthesis and an intracorporeal part comprising the intraocular and the extraocular implant, which interface ensures power supply and a bi-directional data transmission.
