History Second Sight Medical Products, Inc., located in Sylmar, California, was founded in 1998 by Dr. Alfred Mann, Dr. Sam Williams, Dr. Robert Greenberg, Mr. Aaron Mendelsohn, and Mr. Gunnar Bjorg with the goal of creating a retinal prosthesis to provide sight to subjects blinded from outer retinal degenerations, such as retinitis pigmentosa. Second Sight currently employs over 85 employees and has a European office in Lausanne, Switzerland. The first clinical trial (Argus I) began in 2002 (6 subjects in total). With the experience gained from the Argus I trial, and further technological developments, a second generation device was created – the Argus II. For this device, a two-patient pilot study was initiated in Mexico in 2006, followed by a 30-patient trial in 10 centers across Europe and the United States.
