iStent® Inject Your Once-In-A-Lifetime Opportunity to Treat Glaucoma & Cataracts at the Same Time

If you’ve been managing your glaucoma symptoms with medication, and now are preparing for cataract surgery, iStent inject® may be an ideal option for you. Around the world, iStent inject® has helped people with glaucoma successfully manage their intraocular pressure. By taking advantage of this once-in-a-lifetime opportunity during cataract surgery, you can help address both of these conditions at the same time.  


Implanted during cataract surgery, iStent inject® can effectively lower IOP, one of the most important risk factors for glaucoma, and may reduce your reliance on glaucoma medication at the discretion of an eye care professional.

How iStent inject® Works

To help control the increased pressure in your eye associated with glaucoma, iStent inject® creates two bypasses, or openings, between the front part of your eye and its natural drainage pathway to increase the flow of fluid. By creating the permanent bypasses through the primary blockage site (trabecular meshwork), iStent inject® is designed to:


• Improve your eye’s natural outflow to safely lower intraocular pressure

• Work continuously to improve the natural flow of fluid in your eyes

What To Expect With iStent inject®


Before the Procedure

You should continue to use any prescribed eye drops until your procedure, unless directed by your eye care professional. Before surgery, your eye surgeon will go over all the medications you’re currently taking. Be sure to bring a list of your current medications to your pre-operative appointment and be prepared to answer a few questions regarding your medical history.


During the Procedure

The cataract removal and iStent inject® procedure are usually performed under local anesthesia. After your surgeon removes your cataracts, he or she will implant the iStent inject® devices. Once implanted, you will not see or feel the devices.


After the Procedure

iStent inject® is an outpatient procedure, which means you’ll be able to go home the same day following your surgery. After the procedure, you will likely receive antibiotic and anti-inflammatory eye drops to use. Your ophthalmologist will likely schedule an appointment to see you the day following the surgery.


Recovery time is usually quick, but your doctor may recommend that you take a few days off work. You should also refrain from strenuous activities such as sports, lifting heavy objects, or any straining movements that will increase your eye pressure.


Risk Factors

The risks associated with performing cataract surgery with the iStent inject® are similar to those related to performing cataract surgery alone. For more information regarding specific risks associated with your condition, please talk to your eye care professional.
