“We are delighted to receive this incremental $5 million investment from Gregg Williams, as we advance our initiatives for Orion and Argus 2s. We look forward to reporting on our continued progress,” stated Will McGuire, President and CEO of Second Sight.

“This investment reflects my continued profound confidence in our entire Second Sight team. I am strongly encouraged by the initial results reported from the Orion patient feasibility study as well as the size of the potential addressable market opportunity we have identified. In my view, having five out of five of our initial patients report seeing light from virtually all of the electrodes in the Orion array certainly bodes well for the future. I am also very encouraged that Orion received the FDA’s Breakthrough Device designation, which has allowed us to have efficient and constructive interactions with the FDA. We remain committed to advancing the groundbreaking Orion technology and serving a significant unmet need for the millions of blind individuals worldwide who currently have no treatment available,” said Gregg Williams, Chairman of the Board of Second Sight.

About the Argus II Retinal Prosthesis System  

Second Sight's Argus II System provides electrical stimulation that bypasses defunct retinal cells and stimulates remaining viable cells inducing visual perception in individuals with severe to profound retinitis pigmentosa (RP). The Argus II works by converting images captured by a miniature video camera mounted on the patient's glasses into a series of small electrical pulses, which are transmitted wirelessly to an array of electrodes implanted on the surface of the retina. These pulses stimulate the retina's remaining cells, intending to result in the perception of patterns of light in the brain. The patient must learn to interpret these visual patterns, having the potential to regain some visual function. The Argus II is the first artificial retina to receive widespread commercial approval, and is offered at approved centers in Canada, France, Germany, Iran, Italy, Russia, Saudi Arabia, Singapore, South Korea, Spain, Taiwan, Turkey, the United Kingdom, and the United States.

About the Orion Visual Cortical Prosthesis System 

Like the Argus II, the Orion converts images captured by a miniature video camera mounted on the patient's glasses into a series of small electrical pulses. The Orion is designed to transmit these electrical pulses wirelessly to an array of electrodes implanted on the surface of the visual cortex, intended to result in the perception of patterns of light. By bypassing the retina and optic nerve and directly stimulating the visual cortex, a cortical prosthesis system has the potential to restore useful vision to many more patients than the Argus II, including patients completely blinded due to many reasons, including glaucoma, diabetic retinopathy, or forms of cancer and trauma. The Company is currently conducting a feasibility study in the U.S. at two centers: the Ronald Reagan UCLA Medical Center and Baylor College of Medicine in Houston. No published clinical data is yet available for the Orion.
