Long term in vivo biocompatibility evaluation of a microelectrode array based on photosensitive Durimide 7510 polyimide layer implanted within a rabbit eye: (a) phase-contrast image (400×) of the inner retinal morphology at 6 weeks post-implantation (RGC: retinal ganglion cell layer; ILM: inner limiting membrane); (b) light microscope image (400×) of the inner retinal morphology at 6 months post-implantation; (c) light microscope image (400×) of the control rabbit retina; (d) SEM micrograph of the undamaged implanted electrode at 6 months post-operation.
