iStent® — Designed to Reduce IOP in Mild-to-Moderate Glaucoma
iStent® is indicated for use in conjunction with cataract surgery for the reduction of IOP in adult patients with mild-to-moderate open-angle glaucoma currently treated with ocular hypotensive medication. Key advantages to using the device during cataract surgery include:
Performed at the time of cataract surgery, requiring no additional incisions other than those needed for cataract surgery itself.
DIRECTLY IMPROVES THE PHYSIOLOGICAL OUTFLOW
Creates a bypass through the primary blockage site (trabecular meshwork).
EXCELLENT SAFETY PROFILE
The overall incidence of adverse events of performing cataract surgery with iStent® are comparable to performing cataract surgery alone.
RAPID RECOVERY TIME
Patient recovery time is usually rapid, which allows a return to normal activities.
POSITIVE PATIENT OUTCOMES
Clinical studies show that most patients experience a reduction in IOP and a reduction in reliance on glaucoma medication.
Mechanism of Action
The iStent® device improves aqueous outflow through the natural physiological outflow pathway. When the device is implanted in the trabecular meshwork, it stents open that section of the ocular anatomy and allows aqueous humor to flow from the anterior chamber into the Schlemm’s canal. The physiological preservation of the trabecular meshwork ensures a natural episcleral back pressure of 8-11 mm Hg with minimal risk of hypotony. Increasing outflow through the infranasal quadrants has a significant impact on lowering IOP due to the high presence of collector channels.

The iStent® Procedure
iStent® is inserted ab interno through the phaco incision and can be performed under topical anesthesia.
|Fill the anterior chamber with a viscoelastic|
|Introduce the inserter through a phaco incision and advance past the pupillary margin|
|View the angle under high magnification with a gonioprism|
|Approach the upper third of the trabecular meshwork at a 15 degree angle|
|Engage the trabecular meshwork and gently advance the iStent® into Schlemm’s canal|
|Push the button on the inserter to release the iStent® implant|
|Release the button on the inserter and gently tap the side of the snorkel to ensure the device is properly situated|
|Remove inserter and aspirate the viscoelastic|
Easily guides device through the trabecular meshwork into Schlemm’s canal.
• Help to secure placement.
