iStent® - Micro-Invasive Glaucoma Surgery

Pittsburgh Eye Associates now offers the latest surgical advancements in Glaucoma Surgery for patients that also suffer from cataracts. iStent® is the first Micro-Invasive Glaucoma Surgery (MIGS) device that improves your eye’s natural fluid outflow to safely lower eye pressure by creating a permanent opening in the trabecular meshwork.

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.

For patients with combined cataract and open-angle glaucoma, iStent reduces intraocular 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.
