‘The researchers behind the “exciting” project are now planning to conduct human trials in an effort to restore sight to blind or partially sighted people.’

'Can you believe this?” Elizabeth asked a few minutes later. Ahead of her, Christian walked with Jean Bennett, whose lab at Penn produced the gene-laced fluid that gave Christian sight. “It happened so fast,” Elizabeth said. Just three days after his first eye was treated, Christian could see her. “I went from wondering if my son would ever know what I looked like to … well, this,” she said, gesturing at him walking unaided. “It’s like a miracle.”
Christian’s miracle was hard-won. It rose from 20 years of unrelenting work by Bennett and her collaborators, who identified the genetic mutation that crippled Christian’s retina, then figured out how to sneak a good copy of that gene into his eye. Bennett started trials for the therapy merely hoping “that we could detect some hint of improvement.” Nine years later she is astonished that it seems to have worked so well.’
In June 2015 she went to Oxford Eye Hospital, lay on a table, surrendered to anesthesia, and, 10 hours later, awoke with a bionic eye. In what was “without doubt the most complex operation I’ve ever done,” says surgeon Robert MacLaren, the Oxford team slipped between her retina’s delicate layers a freckle-size microchip laden with 1,600 tiny photodiodes. MacLaren’s clinical trial is exploring whether this chip, known as the Alpha, can replace the dead photoreceptors (the famous rods and cones) in the center of Lewis’s retina by translating light into bursts of current that the existing neural network will relay to the brain.
When they turned on the device, Lewis told me last November, “I couldn’t believe it. Suddenly—oh, my God—there’s something there.”

I’m not sure how it’s possible to be so wrong.
