Robot eye surgery?

Product design and development firm Cambridge Consultants created a medical robot capable of performing one of the world's most common but delicate operations: cataract surgery. Carried out around 20 million times per year, this life-changing surgery helps restore sight when a patient develops cataracts, turning their eye cloudy and making it hard for them to see. To counter this, surgeons slice a tiny hole in the eye's lens, remove the part which has clouded over and replace it with a plastic lens -- similar to a contact lens but inside, rather than outside, the eye. While cataract surgery is common, however, things can and do go wrong. The lens being operated on is just 10mm across and -- while surgeons are necessarily steady-handed -- they are performing a 15-20-minute procedure on a tiny surface, using little more than tweezers and a microscope.
