It's a real eye-opener. A surgical robot can make the micro-scale movements needed for the delicate procedure of cataract surgery. Axsis, a small teleoperated system developed by roboticist Chris Wagner and his colleagues at Cambridge Consultants, UK, is designed to cut into the eye with greater accuracy than a human. Globally, 20 million people a year have surgery on cataracts. They develop when the lens of the eye gets cloudy. To restore sight, a surgeon cuts a small hole in the lens, scoops out the cloudy bit, and replaces it with a plastic lens.
