Development of the electronic retinal prosthesis for restoration of sight in patients suffering from the degenerative retinal diseases faces many technological challenges. To achieve significant improvement in the low vision patients the visual acuity of 20/80 would be desirable, which corresponds to the pixel size of 20μm in the retinal implant. Stimulating current strongly (quadratically) depends on distance between electrode and cell. To achieve uniformity in stimulation thresholds, to avoid… CONTINUE READING
