I listened to part of this in the car, and I just had listen to it again. Here is the gist of it
At the age of 45, Michael May, who had been blind since childhood, was given the possibility of sight through a revolutionary stem-cell transplant surgery. Author Robert Kurson has documented May's experiences regaining his sight in a new book, Crashing Through: A True Story of Risk, Adventure, and the Man Who Dared to See

It was interesting to find out that almost no one was happy after the surgery, but most of the blind callers said they would try the surgery even with chance of losing their lives. Also it gave me some perspective on how what I see is heavily interpreted by my brain in order to do anything involving sight. Check it out
