iStent®

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:

MINIMAL INVASIVENESS

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.
