Glaucoma Advancements - iStent Technology

iStent® Trabecular Micro-Bypass

iStent® Trabecular Micro-BypassTechnology has always played an important role in eye care and the treatment of eye diseases. For those ready to undergo cataract surgery advanced technology is now available that can also help manage mild-to-moderate open-angle glaucoma.  Advancements in technology allow your surgeon to add another step to your cataract surgery that will allow you to treat your open-angle glaucoma in a completely new way. This is important because once glaucoma diagnosed, most patients spend the rest of their lives putting one, two or even three different kinds of drops in every day. Unfortunately, all of these drops are not only inconvenient, but can also be very expensive. The iStent Trabecular Micro-Bypass Stent is designed to reduce your eye pressure and you can have it done at the same time you have cataract surgery.


One small lmplant can deliver big results in mild-to-moderate open-angle glaucoma

While mild-to-moderate open-angle glaucoma is very common, many people are unaware of their condition, especially in the early stages, when their vision may be unaffected. In many people, open-angle glaucoma is characterized by an increase in the intraocular pressure (IOP) of your eye. This pressure is caused by the buildup of fluid within the eye. In Most cases, glaucoma progresses slowly, but its damage is irreparable. 

The world’s tiniest medical device—iStent—is 20,000 times smaller than the intraocular lenses (IOL) used in your cataract surgery. But the size of iStent is only part of its story. By increasing the eye’s ability to drain fluid, this technology is designed to reduce the pressure in your eye.

In a U.S. clinical study, 68% of glaucoma patients who received iStent remained medication free at 12 months while sustaining a target IOP of ≤ 21 mm Hg vs. only 50% of patients who underwent cataract surgery alone.

iStent works like the stents used to prevent heart attacks and strokes. When blood vessels get clogged, a stent creates access to the vessel flow. While a highly innovative technology, how iStent works is very similar:

  • If you have glaucoma, over time the eye’s natural drainage system becomes clogged
  • iStent creates a permanent opening through the blockage to improve the eye’s natural outflow
  • Restoring this mechanism lowers and controls pressure within the eye.

iStent is implanted during your cataract surgery procedure. Once implanted, iStent will begin working to safely and effectively manage pressure. What’s more, patients who receive iStent may experience a reduction in glaucoma medications; but this will be at the discretion of your surgeon.

Sierra Nevada Eye Center remains committed to providing the latest cutting-edge technology to our patients. Dr. Wolff was the first surgeon to implant the iStent in northern Nevada.
