Glaukos iStent Infinite
Glaukos iStent Infinite for Glaucoma
Advanced Multi-Stent MIGS Procedure | Westlake Eye Specialists in Austin, Kyle, Killeen & New Braunfels
For patients with advanced glaucoma who need more than medications or single-stent options, Glaukos iStent Infinite® offers a powerful new solution. As the latest innovation in minimally invasive glaucoma surgery (MIGS), this FDA-approved device features three precision-placed stents to enhance fluid drainage and reduce intraocular pressure (IOP).
At Westlake Eye Specialists, our glaucoma patients across Austin, Kyle, Killeen, and New Braunfels trust Dr. Zarmeena Vendal, MD, a Harvard-trained glaucoma specialist, for personalized care and cutting-edge treatment options like the iStent Infinite.
What Is the iStent Infinite?
The iStent Infinite is a breakthrough MIGS device consisting of three biocompatible titanium stents that are inserted into the eye’s natural drainage system—specifically the trabecular meshwork.
Unlike the dual-stent iStent Inject, the iStent Infinite is designed for standalone use, meaning it does not need to be performed during cataract surgery. It’s ideal for patients whose glaucoma continues to progress despite being on multiple medications or after previous surgical interventions.
Key Benefits of iStent Infinite
- Three stents = more fluid drainage and more IOP control
- Standalone MIGS procedure—not dependent on cataract surgery
- May reduce or eliminate the need for multiple glaucoma drops
- Performed with minimal trauma to surrounding tissue
- Faster healing and recovery compared to traditional surgeries
- Covered by most insurances for qualifying patients
If you’ve been told you need additional glaucoma control beyond drops or earlier MIGS, the iStent Infinite could be the next step in your care.
Who Is a Candidate for iStent Infinite?
Dr. Zarmeena Vendal may recommend iStent Infinite if you:
- Have moderate to advanced primary open-angle glaucoma
- Need better IOP control beyond what drops or SLT provide
- Previously had iStent Inject, but require additional pressure-lowering
- Are not planning cataract surgery, or have already had it
- Want to avoid traditional glaucoma surgeries like trabeculectomy
As with all surgical options, candidacy depends on individual eye anatomy and glaucoma severity. At Westlake Eye Specialists, we take time to evaluate every case closely.
What to Expect During the Procedure
Unlike earlier stents that must be paired with cataract removal, the iStent Infinite is performed independently in a short outpatient setting.
- Topical anesthesia is applied to numb the eye
- A small incision is made to access the drainage angle
- Dr. Vendal precisely places three micro-stents into the trabecular meshwork
- The incision is self-healing—no stitches required
- The entire procedure takes around 15–20 minutes
Recovery & Results
- Most patients resume daily activities within 24–48 hours
- Expect mild temporary irritation or blurred vision
- Pressure-lowering effects begin in days to weeks
- Follow-up appointments are scheduled to monitor IOP and healing
- Some patients experience enough improvement to reduce or eliminate eye drops
Clinical trials have shown that iStent Infinite can achieve sustained IOP reduction over time, making it a valuable tool for long-term glaucoma management.
