iStent Trabecular Micro-Bypass


The iStent is engineered to fit into Schlemm canal, enabling steady physiologic outflow from a snorkel projecting into the anterior chamber. The self-trephinating tip guides device through the trabecular meshwork while retention arches secure placement.

  • Material: Surgical-grade Nonferromagnetic Titanium with heparin coating
  • The device measures 1 mm in length, 0.33 mm in height, and has a 120 micron lumen diameter
  • Preservation of the trabecular meshwork ensures a natural episcleral back pressure of 8-11 mm Hg with minimal risk of hypotony

Great way to do a combined cataract and glaucoma surgery! You can easily lower your patient's IOP without the trauma associated with traditional filtering procedures.

Very atraumatic insertion after the initial learning curve. Excellent safety profile. My patients have averaged 1.5 medication decrease concurrent with cataract surgery.

Peter C., MD, United States

The iStent has an excellent safety profile. Even for novice surgeons, it requires very little additional time added to traditional cataract surgery. Patients who are taking only 1 glaucoma medication, in my opinion, benefit most since they have the added convenience of not having to do medications daily.

Like the idea and the engineering. Still in the learning curve.
