Schedule your eye exam today!
Who is a Candidate for an iStent?
The iStent is intended for specific types of glaucoma and patient situations.
The iStent is FDA-approved for adults with mild to moderate open-angle glaucoma who are also having cataract surgery performed.
It may be suitable for patients currently using eye drops to manage their eye pressure.
The iStent is not recommended for all forms of glaucoma (such as angle-closure glaucoma). Your eye doctor will determine if it is appropriate based on your diagnosis.
What Are the Benefits of the iStent?
The iStent offers several advantages for glaucoma and cataract patients.
The device can significantly reduce intraocular pressure, which is essential in slowing glaucoma progression.
Many patients need fewer or even no daily glaucoma eye drops after surgery.
The iStent is placed during cataract surgery, so both conditions are addressed with a single operation and recovery period.
As a micro-invasive procedure, the iStent preserves the natural structures of the eye and is associated with a strong safety profile.
The implant is non-magnetic and does not interfere with future medical treatments or imaging tests, such as MRI scans.
What Should I Expect After Surgery?
After surgery, your doctor will closely monitor your healing and adjust any medications as needed.
Several follow-up visits will be scheduled to check eye pressure and monitor healing and function.
Your glaucoma medications will be reassessed; some patients can reduce or stop them.
Most patients return to normal routines within days, following standard advice for post-cataract care.
Frequently Asked Questions
Learn more about the iStent from these commonly asked questions.
The iStent is designed to remain securely in place within the trabecular meshwork. Dislodgement is extremely rare if post-surgery guidelines are followed.
Patients do not typically feel the iStent. It is very small and does not cause irritation or discomfort after implantation. Any unusual pain should be reported to your ophthalmologist.
Improvement in eye pressure may be noticed within days or weeks, but the benefit varies depending on individual healing and glaucoma severity. Your doctor will check your progress at follow-ups.
The iStent has a strong safety record and a low complication rate. Rarely, blockage of the stent, scarring, or insufficient pressure lowering may occur. Long-term follow-up is important to track results.
The iStent's small size and safe placement usually do not interfere with future eye treatments. Your surgeon will take it into account when planning any additional procedures.
No restrictions exist for flying or activities such as scuba diving. The iStent is stable and unaffected by changes in air or water pressure.
Most insurance plans, including Medicare, typically cover the iStent when medically necessary and combined with cataract surgery. Confirm your coverage with your provider prior to surgery.
Removal is rarely needed but can be done by a qualified surgeon if complications arise. Most patients do not need removal.
The iStent does not cure glaucoma but helps control intraocular pressure and can slow disease progression. Lifelong medical monitoring remains essential.
Certain eye conditions or medications can affect iStent outcomes. A thorough evaluation by your ophthalmologist helps tailor your treatment for the best results.
No, the iStent is microscopic and cannot be seen or felt after implantation.
The iStent is constructed from surgical-grade titanium, a biocompatible material used in many medical implants.
Yes, the iStent is MRI-compatible and safe for imaging.
The iStent is a permanent implant, designed to last a lifetime.
The iStent addresses glaucoma pressure, not refractive error or presbyopia. Glasses needs are determined by cataract surgery outcome and overall eye health.
