What happens to users of cutting-edge implants when the only company that makes the technology runs out of money? That’s the question we set out to answer during a year-long investigation of the Argus II retinal implant, manufactured by a California company called Second Sight Medical Products. The investigation was published by IEEE Spectrum in February and covered in a recent Science Friday broadcast.
Strickland had first written for Spectrum about the company back in 2011, lauding the development of a revolutionary eye implant that restored a crude kind of artificial vision to blind people involved in Second Sight’s clinical trials. That article featured a New Yorker named Barbara Campbell, who had been completely blind since her 30s because of a genetic condition called retinitis pigmentosa, but who could then make out rough shapes, figures and lights. The retinal implant connected wirelessly to a pair of sunglasses housing a low-resolution video camera. In 2013, the Argus II system was the first visual prosthesis to be approved by the FDA.
As the Argus II rolled out in the United States and around the world, many more such stories were written, typically showing users delighted to regain some vision — even if it was only flashes of light and shades of gray. Globally, over 350 people would ultimately have an Argus II implanted.
Late in 2020, Strickland revisited Second Sight to write a blog post about its latest project: a brain implant that stimulates the user’s visual cortex directly, potentially opening up its prosthetic system to a much wider group of people with vision challenges. Tucked away in that post were a few lines noting that the company had suspended production of the Argus II device and had recently suffered financial difficulties, nearly going out of business in early 2020. Strickland tried to contact the company for a status update, but didn’t get a response to her emails and phone calls.
