Glaucoma and Cataract Surgery

The iStent: Managing Glaucoma while Treating Cataracts

If you have glaucoma and cataracts, we can add another step to cataract surgery to manage mild‑to‑moderate open‑angle glaucoma in a completely new way.

The iStent Trabecular Micro‑Bypass stent is a new surgical device for glaucoma that is designed to improve aqueous outflow to safely lower intraocular pressure and reduce the medication burden.

This is important because once diagnosed with glaucoma, most patients will spend the rest of their lives putting one, two or even three different kinds of drops in every day. All of these drops are not only inconvenient, but expensive. The iStent is designed to reduce eye pressure and is implanted during cataract surgery.

The 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.

As an iStent‑trained surgeon, Dr. Joseph Parisi, Medical Director at Clemson Eye, offers this treatment solution to glaucoma patients who come to us for cataract surgery.

Implanting the iStent during cataract surgery is covered by most insurance plans, Medicare and Medicaid. Currently, the FDA only permits the procedure to be performed in conjunction with cataract surgery.
