Robots can perform surgery inside your eyeballs

Doctors at Oxford University made medical history recently by successfully completing the first robot-assisted intraocular surgery. Robert MacLaren, Professor of Ophthalmology at the university, and his team managed to gently peel off a 1/1000th millimeter membrane from the inside of a patient's eye. To do so, the team relied on a cutting-edge medical device known as the Robotic Retinal Dissection Device, or R2D2. The R2D2, developed by Dutch medical robotics firm Preceyes BV, is designed to perform keyhole surgery, entering and exiting the eyeball through a single, sub-millimeter hole. What's more, it's built to be exceedingly steady, especially given the tight tolerances within which it works.
