Famous for its film studios and music industry, Los Angeles is a city rich in innovation and creativity. Today, it is also home to a raft of companies that are helping to transform lives with breakthroughs in medical science.
At Second Sight Medical Products, based in the San Fernando Valley area, researchers are helping to lead the fight against loss of sight. The Argus II Retinal Prosthesis System is the world's first FDA approved 'bionic' eye, a sophisticated piece of technology that is helping the blind to see.
"It's the first time that there's ever been a treatment that ophthalmologists have for patients who are completely blind," Dr Robert Greenberg, CEO of Second Sight Medical Products, told CNBC's Innovation Cities.
For more than 30 years Arizona resident Lisa Kulik has been living with retinitis pigmentosa, a degenerative disease which eventually leads to blindness.
"When I was diagnosed… I was pretty much told by every doctor that I saw that there was no cure, and there was nothing that I can do," Kulik told Innovation Cities.
