Abstract

A method for manufacturing an intraocular retinal implant including: providing a mold capable of supporting growth of a layer of doped diamond, the mold including, on one face, elements all depressed or all projecting with respect to the surface of the face, and constituting a pattern cavity for the electrodes of the implant which it is desired to obtain; producing the doped diamond electrodes by growing a layer of doped diamond in all or part of a space occupied by the pattern cavity elements; forming a first insulating layer on the face of the mold including the pattern cavity; producing interconnection lines by depositing an electrically conductive material at least in spaces not covered by the first insulating layer; forming a second insulating layer on the mold face including the pattern cavity, the second layer covering the interconnection lines, the first and second insulating layers forming a flexible plate of the implant; removing the mold.
