Your next eye surgeon might just be a robot.

Startup ForSight Robotics said Tuesday it raised $125 million to expand its robotics platform that it says is the first in the world for cataracts and other eye diseases. Cataract surgery is one of the most common procedures, with more than 4 million done in the U.S. annually, but there aren’t enough doctors to meet the demand.

The company, now valued at an estimated $500 million, is testing its technology on pig eyes, but plans to complete its first full robotic surgery on a person later this year. Long term, cofounder Dr. Joseph Nathan told Forbes the technology could also be used for other surgeries, such as retina repairs and glaucoma treatments.
