For patients with combined cataract and open-angle glaucoma, iStent reduces introcular pressure (IOP) by improving aqueous humor outflow. Inserted through a 1.5-mm corneal incision, iStent is the only FDA-approved device for the treatment of mild to moderate open-angle glaucoma.
iStent is the smallest medical device ever approved by the FDA. It is placed in your eye during cataract surgery and is so small that you won’t be able to see or feel it after the procedure is over. iStent is designed to create a permanent opening in your trabecular meshwork, and works continuously to improve the outflow of fluid from your eyes to help control eye pressure.
