iStent Surgery

If you have both glaucoma and cataracts, iStent is an FDA-approved treatment that can significantly reduce eye pressure.


The iStent Trabecular Micro-Bypass stent is a surgical therapy for glaucoma that is designed to improve aqueous outflow to safely lower Intraocular Pressure (IOP) and may reduce medication burden.

iStent is the smallest medical device ever approved by the FDA and is placed in your eye during cataract surgery. It is so small, you won’t be able to see or feel it after surgery but it will be continuously working to help reduce your eye pressure.


Every day, you are probably taking one or more eye drops to control your eye pressure. By improving the outflow of fluid from your eyes, iStent works to help control your eye pressure. After implantation of iStent, many patients are able to control their eye pressure.

Controlling eye pressure is extremely important to reduce the risk for vision loss due to glaucoma. If you forget to take your eye drops or ‘skip a dose’, this can cause large changes in your eye pressure. Large changes in eye pressure can increases the risk for vision loss.
