iStent is a breakthrough device designed for the effective management of open-angle glaucoma. By creating a new drainage pathway, it helps to lower eye pressure and improve quality of life, allowing patients to focus on what they love without the burden of daily medications.
iStent is a tiny medical device that helps manage glaucoma by improving fluid drainage in the eye and lowering eye pressure. This implant can make a big difference for people with open-angle glaucoma, often reducing the need for daily eye drops and helping to protect vision over time.
iStent is one of the smallest medical implants used in the human body, specifically designed to create a new pathway for fluid to drain from the eye. This helps control eye pressure without requiring traditional, more invasive surgery.
iStent was developed to provide a less invasive way to treat glaucoma compared to traditional surgeries. It was first approved by the U.S. FDA in 2012 and has since been implanted successfully in thousands of patients worldwide, with studies showing it can lower eye pressure by an average of 15–30%.
There are different versions of iStent, including the original iStent, iStent inject, and the newer iStent inject W. Some models use a single stent, while the iStent inject W uses two tiny stents to provide even more effective drainage. Your ophthalmologist will recommend the best version for your specific condition.
Each iStent is made from medical-grade titanium, a material known for its safety and compatibility with the human body. Its microscopic size allows a surgeon to place it through a tiny, self-healing incision, making the procedure minimally invasive.
iStent is manufactured by Glaukos Corporation, a company recognized for its innovation in minimally invasive glaucoma surgery (MIGS). Their devices are trusted by eye care specialists for their proven safety and long-term effectiveness in managing glaucoma.
iStent works by bypassing blockages in the eye’s natural drainage system, allowing fluid to flow out more freely. By reducing pressure inside the eye, it helps slow or prevent further damage to the optic nerve from glaucoma.
In a healthy eye, fluid drains through a mesh-like tissue called the trabecular meshwork. Glaucoma often occurs when this pathway becomes blocked, causing eye pressure to rise. iStent creates a small, permanent opening through this blockage, restoring the eye's natural outflow.
iStent is most often placed during cataract surgery. This combined approach is highly convenient, as it allows patients to address both cataracts and glaucoma in a single procedure, minimizing healing time and simplifying the treatment process.
Once implanted, iStent is permanent and requires no maintenance. Many patients experience stable, controlled eye pressure and remain less dependent on glaucoma medications for years. Regular follow-up visits are still essential to monitor your eye health.
iStent offers several significant advantages for glaucoma patients. It is a safe and effective way to lower eye pressure, often reduces the burden of daily medications, and involves a quick, minimally invasive procedure.
By improving the eye's fluid drainage, iStent effectively lowers intraocular pressure, which is the primary goal of glaucoma treatment. This helps slow the progression of the disease and protect your vision from further damage.
After iStent placement, many people are able to reduce or even stop using their daily glaucoma eye drops. This can minimize medication side effects, lower costs, and simplify your daily routine.
Unlike traditional glaucoma surgeries, the iStent procedure requires only a very small incision and adds just a few minutes to cataract surgery. The recovery is typically much faster, and there is a lower risk of complications.
With better eye pressure control and less reliance on medications, patients often feel more confident and less burdened by their glaucoma management. This allows you to focus more on the activities you enjoy.
Because iStent is a tissue-sparing procedure, it does not prevent you from having other glaucoma treatments in the future if they become necessary. This allows for a flexible, step-by-step approach to managing your eye health over a lifetime.
Placing the iStent is a quick outpatient procedure, most often performed at the same time as cataract surgery. It is done using local anesthesia and is generally comfortable for patients.
Your doctor will conduct a complete eye exam to confirm that iStent is the right option for you. You may be asked to adjust your glaucoma medications before surgery and will need to arrange for a ride home afterward.
Your eye will be numbed with drops to ensure comfort. The surgeon then makes a tiny incision and uses a special applicator to insert the stent into the eye's drainage channel. Most patients feel little to no discomfort, perhaps only a slight sensation of pressure.
It is normal to experience mild irritation, redness, or light sensitivity for the first few days. Your doctor will prescribe eye drops to aid healing and prevent infection. Most patients return home the same day.
Recovery from iStent placement is usually smooth and quick. Following your doctor’s aftercare instructions is essential for ensuring the best possible outcome and long-term success.
Initial healing takes about one week, during which time your vision will gradually improve. The full benefits of the iStent on your eye pressure are often seen within one to three months as the eye stabilizes.
To protect your eyes and promote healing, follow these important guidelines:
Contact your eye care team immediately if you experience increasing pain, a significant change in vision, worsening redness, or any discharge from your eye. These could be signs of a complication that requires prompt attention.

iStent has a strong safety profile, but like any medical procedure, it carries some risks. Most side effects are mild and temporary, resolving on their own with proper care.
The most common side effects include temporary blurriness, mild redness, light sensitivity, or a small amount of bleeding inside the eye. These issues typically resolve within a few days to weeks after the procedure.
Though uncommon, potential complications can include the stent moving out of position, blockage of the stent, or inflammation inside the eye. The risk of a serious infection is very low but requires immediate treatment if it occurs.
Choosing an experienced surgeon and carefully following all pre- and post-operative instructions are the best ways to minimize risks. Be sure to provide your doctor with your complete medical history so they can tailor your care plan for the safest results.
An eye care specialist can determine if iStent is a good option based on your glaucoma stage, eye health, and treatment goals. It is most often recommended for adults with mild to moderate open-angle glaucoma.
The best candidates are typically adults with mild to moderate open-angle glaucoma who are already scheduled for cataract surgery or who struggle with consistently using eye drops. The procedure is FDA-approved for adults 18 and older.
iStent may not be suitable for patients with certain types of glaucoma, such as angle-closure glaucoma, or those with significant scarring in the eye's drainage angle from a previous surgery or injury. A thorough examination is needed to confirm eligibility.
If iStent is not the right fit, other options may be available. These include other MIGS devices, laser treatments like selective laser trabeculoplasty (SLT), or traditional glaucoma surgeries for more advanced cases.
To make an informed decision, consider asking your doctor about the success rate of the procedure, recovery expectations, total costs and insurance coverage, and how iStent compares to other treatments available for your condition.
If you have glaucoma, exploring treatment options like iStent is a proactive step toward preserving your vision. The best way to learn if this procedure is right for you is to schedule a consultation with your eye doctor for a complete evaluation.
