Glaucoma Surgery with Cataract Surgery
iStent® Trabecular Micro-Bypass: add an exciting glaucoma technology to your cataract
Technology has always played an important role in eye care. Today, almost every aspect of vision is connected to a product or procedure that wasn’t available even ten short years ago.
The cataract surgery you are scheduled for is a good example of how innovations can make a difference. Every aspect of it utilizes recently developed technology that will help us improve your vision. Today, this includes managing your mild-to-moderate open-angle glaucoma: because now we are able to add another step to your cataract surgery that allows you to treat your open-angle glaucoma in a completely new way. This is important because once diagnosed, you and most patients like you will spend the rest of your lives putting one, two or even three different kinds of drops in every day. Unfortunately, all of these drops will not only be inconvenient, but potentially 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.
iStent: the world’s smallest medical implant delivers big results in mild-to-moderate openangle 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. Too much fluid raises pressure, which can cause the gradual loss of vision. And while glaucoma moves slowly, 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.
A breakthrough in glaucoma Technology
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 elegantly simple:
• 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
• Restoring this mechanism lowers and controls pressure within the eye
iStent: managing glaucoma while treating your cataracts
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 physician.
Indication for Use.
The iStent® Trabecular Micro-Bypass Stent (Models GTS100R and GTS100L) is indicated for use in conjunction with cataract surgery for the reduction of intraocular pressure (IOP) in
adult patients with mild to moderate open-angle glaucoma currently treated with ocular
The iStent® is contraindicated in eyes with primary or secondary angle closure glaucoma,
including neovascular glaucoma, as well as in patients with retrobulbar tumor, thyroid eye
disease, Sturge-Weber Syndrome or any other type of condition that may cause elevated
episcleral venous pressure.
Gonioscopy should be performed prior to surgery to exclude PAS, rubeosis, and other angle
abnormalities or conditions that would prohibit adequate visualization of the angle that could
lead to improper placement of the stent and pose a hazard. The iStent® is MR-Conditional
meaning that the device is safe for use in a specified MR environment under specified
conditions, please see label for details.
