It's called endoscopic photo-coagulation, or ECP.
A device about the size of a pencil uses a camera, light and lasers to make tiny incisions in the eye.
For the first time doctors can actually "see" what they're treating which allows them to be much more precise.
That's great news for patients like Martha Cole who deal with the burden of glaucoma every day.
"I think it'd be just great to get rid of all that medicine and have that extra freedom. And I probably won't have to go to the doctor as often," said Cole.
ECP is also a less invasive procedure. It only takes about 20 minutes per eye, and recovery time can be as short as a day.
Glaucoma is the leading cause of preventable vision loss in the U.S. effecting more than 2 million people over the age of 40.
