Transcript for Man Sees for the 1st Time in 30 Years
Robin, over to you. An incredible medical breakthrough. Imagine this, being plunged into a world of darkness. Told you would never see again only to be given a second chance at sight. You're about to witness technology part of a digital series. My company, we are launching today the future of health. You'll find it on webmd. Larry lester was 33 years old when he got the horrible news. The ophthalmologist said you're going to go blind. It was very devastating. It was like the wind got knocked out of me. It was tough. Blindness came quickly and soon Larry lived his life in the dark. His wife by his side. And for another 33 years the couple coped. Then in 2014 a breakthrough they never imagined. The possibility that Larry could see again. Look up. It's called the rgus 2 system. The world's first fda device designed to restore vision to the blind. Basically a bionic eye. How does this work? How does it restore sight? It starts with electrodes implanted on the patient's retina and the patient wears eyeglasses and has a video camera that captures the images and sends them to a unit that the patient wear that is sends electrical impulses back to the ecelectrodes and then to the brain which allows them to decipher light and dark vision for them. It's impossible to tell what the patient can see but it may be something like this. It's not Normal vision as you or I know it but what they do get is crude series of flashes of lights in a fpixel ted fashion that allow them to make better sense. In October 2014 it was time for Dr. Paul Hahn to turn on the device of his patient. I did a countdown just to catch my own breath. Three, two, one. And then I hit the button. Yes. Can you see? Oh, my goodness. Can you see Larry? Yes. Oh, my goodness. Can I give him a kiss? Yes. Oh, yes. It was so overwhelming. I think my head rocked back a bit. It's hard to put in words because for the first time in 33 years I'm seeing light. So you can see the wall? That's where it changes. That's where it changes, Larry. Right there. It's so incredibly basic, it's light. And it's in my case, sight. My bionic man. That is so cool, Larry. Recently Larry's son-in-law rigged a set of Christmas lights around a basketball hoop. So I was able to make about four out of seven baskets. Oh. Yay! You did it. That's pretty positive. That's good stuff. That's great stuff. So happy for Larry and his family. A remarkable story of hope. That's just a sneak peek of one of five episodes, each one having a medical breakthrough, a noninvasive obesity treatment to 3D printers transplanting organ transplants to an experimental procedure that allows women without a womb to carry babies of their own. Amazing. We're going to be showcasing the people coming up with this technology and the wonderful people who are fortunate to be benefitting from this. So inspirational from the medical standpoint and the patient. The name of the series says it all. The future. We're teaming up with team webmd. Good stuff. Ginger having the final check of the weather. Hey, guys. You know, it is spring when I
