How does a laser beam repair a retina?

Answer:
The laser works like a sewing machine to repair a detached retina, the membrane that lines the interior of the eye. The laser beam is adjusted so that it can pass harmlessly through the lens and focus on tiny spots around the damaged area of the retina. When it is focused, the beam has the intensity to "weld" or seal the detached area of the retina back against the wall of the eyeball.
