Argus II retinal prosthesis (2013)
The FDA approved Argus II, the first retinal prosthesis, for adults with advanced retinitis pigmentosa. The device required surgical implantation of a 60-electrode array on the retina plus a camera on eyeglasses.
Patients could detect light and identify large shapes, but resolution remained very limited.
The device demonstrated that restoring some vision is possible without intact photoreceptors, but its invasiveness and cost restricted adoption.
Prosthe6 aims to achieve what Argus II did with a drug instead of surgery, at a fraction of the complexity.
