“I was blind once but now I can see.” The words are no longer the sole property of religious testimony and literature. Medical progress is being made in the restoration of vision as evidenced by Second Sight’s Argus II, a retinal prosthesis already on the market in Europe, and Bio-Retina from NanoRetina, which is to start clinical trials next year. Second Sight is a California company with a European office in Lausanne. Its Argus II Retinal Prosthesis System was developed to provide electrical stimulation of the retina to induce visual perception. The Argus II is an eye implant system that includes antenna, electronics case and electrode array. The $115,000 procedure entrails a four hour operation under full anesthesia.
