The laser has been an important innovation for As we get eye repair. older, our eyes change shape and our vision becomes blurred. This problem can be corrected by eye glasses, but many of us would prefer not to wear glasses. A new medical procedure uses a laser to reshape the lens of our eye and restore our perfect vision, without glasses. Other laser procedures can repair problems inside our eyes. For example, sometimes the retina of our eye comes loose(detached retina), which can cause blindness. Without having to cut the eye open, a doctor can shine a special laser through the lens and actually"weld" the detached retina back into place. Another inner eye problem is bleeding. If a tiny blood vessel inside our eye breaks, blood can flow onto the retina and permanently destroy the tiny vision receptors. If this condition is caught quickly enough, a laser can be used to seal the blood vessel to stop the bleeding, and even to clean up (burn off or vaporize) some of the blood that flowed onto the retina. These procedures are now widely available and have restored or retained the sight of many people.
