How iStent inject® W Works

How iStent inject® W Works

Glaucoma is commonly associated with increased pressure in the eye. To help control this pressure, two tiny iStent inject® W stents are gently inserted into your eye during cataract surgery.

The iStent inject® W stents create two bypasses, or openings, between the front part of your eye and its natural ability to drain fluid. Once inserted, you will not be able to see or feel the stents, but they will be working to help reduce your eye pressure.

Glaucoma is a common vision condition that affects millions of people around the world and can have a significant impact on your quality of life.

If your doctor has recommended you undergo cataract surgery, you now have a once-in-a-lifetime opportunity to treat your mild-to-moderate open-angle glaucoma at the same time as your cataract surgery with the iStent inject® W.

Glaucoma is a progressive disease of the eye that, if left untreated, can cause vision impairments or even blindness.

The most significant risk factor for the development and progression of open-angle glaucoma is elevated pressure in the eye.

This increase in eye pressure, also known as intraocular pressure, occurs when the fluid in the eye accumulates and cannot drain naturally.

High intraocular pressure can potentially lead to permanent vision loss.

Unfortunately, there is no cure for glaucoma. Most people take 1, 2, or even 3 medications daily to control their glaucoma.

However, if you’re currently managing your glaucoma with medications and are now preparing for cataract surgery, the iStent inject® W may be an ideal option for you.

FDA approved, iStent inject® W is one of the world’s smallest medical device known to be implanted in the human body.

To help control the increased intraocular pressure associated with glaucoma, two tiny stents are gently inserted in your eye during your cataract surgery. Once inserted, you will not be able to see or feel the device.

iStent inject® W works by creating two bypasses or openings between the front part of your eye to its natural drainage pathway to restore your eye’s natural ability to drain fluid.

By lowering eye pressure, iStent inject® W may also reduce your need for glaucoma medications, but this will be at the discretion of the eye care professional managing your glaucoma.

Worldwide, iStent inject® W is helping people with glaucoma successfully manage their intraocular pressure.
