Opening my eyes this morning, I was pleased to see the sun coming up. For 12 children in China there's now the chance to see the sunrise again, thanks to a ground-breaking operation.

Cataracts cause blindness by clouding the eye's lens. Usually, surgeons replace the lens with a plastic one. This new procedure only removes the cloudy part, leaving the eye's own stem cells to repair the damage.

I think techniques where the body's own cells repair damage are the future of medicine. I can't wait to see how they develop.
