iStent Implantation

iStent implantation procedure

Insertion of the iStent® following successful cataract surgery.

iStent is the first MIGS device that improves your eye’s natural fluid outflow to safely lower eye pressure by creating a permanent opening in the trabecular meshwork. Proven safe and effective, the iStent Trabecular Micro-Bypass:

  • Is safely implanted during cataract surgery
  • Spares important eye tissue that is often damaged by traditional surgeries
  • Does not limit treatment options that could help maintain your vision in the future

iStent is the smallest medical device ever approved by the FDA. It is placed in your eye during cataract surgery and is so small that you won’t be able to see or feel it after the procedure is over. iStent is designed to create a permanent opening in your trabecular meshwork, and works continuously to improve the outflow of fluid from your eyes to help control eye pressure.

For patients with combined cataract and open-angle glaucoma, iStent reduces introcular pressure (IOP) by improving aqueous humor outflow. Inserted through a 1.5-mm corneal incision, iStent is the only FDA-approved device for the treatment of mild to moderate open-angle glaucoma.

Indication for use

The iStent Trabecular Micro-Bypass Stent (Models GTS100R and GTS100L) is indicated for use in conjunction with cataract surgery for the reduction of intraocular pressure (IOP) in adult patients with mild to moderate open-angle glaucoma currently treated with ocular hypotensive medication.
