Wow, I had no idea. I had never heard of the Miracle Surgery and it sounded too amazing to be true but here's the information from the 20x20x20 site. Awesome that only $300 can save someone from being blind.
"It takes just a few minutes. Through a small incision, the surgeon removes the defective lens that’s causing the blindness and replaces it with an artificial lens that costs as little as $2. No stitches needed – just a bandage to protect the eye for a few hours. When it’s removed, the patient opens their eyes and they can see!"
