iStent inject® W

iStent inject® W – Two Injectable Stents. One Incredible Game-changer.

iStent inject® W is indicated for use in conjunction with cataract surgery for the reduction of IOP in adult patients with mild-to-moderate primary open-angle glaucoma. Key advantages to using the Glaukos trabecular micro-bypass device during cataract surgery include:

  • Optimized Outflow: Two multi-directional stents designed to restore natural outflow
  • Clinically Proven: Significant IOP reduction across a wide range of clinical studies1-2
  • Procedural Elegance: Predictability and precision to meet the needs of your practice
  • Proven Safety: Safety profile similar to cataract surgery alone1

All with the exceptional customer support you’ve come to expect from Glaukos.

Mechanism of Action: Restoring the Natural Outflow Pathway

An anatomical image of the angle of the eye shows where the two iStent inject® W micro-bypass stents are implanted into the trabecular meshwork-the main source of resistance for aqueous outflow-resulting in multi-directional flow through Schlemm's canal.

iStent inject® W creates two patent bypass pathways through the trabecular meshwork—the main source of resistance for aqueous outflow—resulting in multi-directional flow through Schlemm’s canal. And it is one of the smallest medical devices known to be implanted in the human body. Together, these unique advantages are designed to provide exceptional results in a truly micro-invasive approach.

Optimize Outflow

An illustration of the eye shows how the two iStent inject® W micro-bypass stents are implanted two to three clock hours apart into the trabecular meshwork to deliver access to multiple collector channels and arcs of flow that can span five to six clock hours.Glaukos trabecular micro-bypass stents are placed two to three clock hours apart. The stents are multi-directional and together, they are designed to deliver access to multiple collector channels and arcs of flow that can span five to six clock hours. The stents may also re-establish flow in previously dormant outflow channels.1

Prioritizing Safety and Outcomes

Putting the primary emphasis on maximizing benefits and minimizing long-term complications, iStent inject® W is designed to support optimal outcomes after cataract surgery and much more:

  • Micro-invasive and astigmatically-neutral
  • Utilizes the conventional outflow pathway
  • Leaves natural anatomy intact, preserving the potential for future treatment options, including drug delivery devices
  • Minimally traumatic to delicate eye tissue and spares conjunctival tissue
  • Reduces risk of hypotony by utilizing the natural episcleral venous pressure
  • Offers postoperative care profile similar to cataract surgery

Watch How it Works


Exceptional Elegance. Advanced Innovation.

The iStent inject® W System is engineered to provide an enhanced surgical experience and ensure confident delivery, for every procedure. With a streamlined injector system and next-generation stent design, featuring a wide flange at its base, iStent inject® W is designed to optimize stent visualization and placement, enhance procedural predictability, and increase peace of mind.

Images of the Glaukos iStent inject® W device are enlarged to show the design including the four side flow outlets to optmize natural outflow, the insertion tube with window to visualize the stents during implantation and the preloaded stents in the single-use, sterile injector. The iStent inject® W is made of medical grade titanium.

An image of the Glaukos iStent inject® inserter is enlarged to show the ergonomic design including the insertion sleeve retraction button, the stent delivery button and the 23-ga sleeve.
