Minimally Invasive Glaucoma Surgery (MIGS)

In the last two decades, advancements in minimally invasive glaucoma surgery (MIGS) have become an extremely safe and effective option for managing mild to moderate glaucoma. MIGS lowers intraocular pressure by enhancing the outflow of the aqueous (clear fluid between the lens and cornea). This can be achieved by using a laser, surgical device, or a microstent to reduce pressure by expand outflow. MIGS treatments can reduce the dependence of medicated eye drops, benefiting the patient by saving money over time and having fewer daily interruptions to apply eye drops. There are a number of MIGs devices that your surgeon can choose from depending on the characteristics of your eyes.

  • iStent, is the first device that improves your eye’s natural fluid outflow to safely lower eye pressure by creating a permanent opening in the eye meshwork. 
  • Hydrus, expands the eye’s natural drainage canal.
  • Kahook, a goniotomy blade created to produce a more complete removal of trabecular meshwork through a minimally invasive approach.
  • Xen, a surgical implant designed to lower high eye pressure in open angle glaucoma patients.
  • Omni, is designed to perform two implant free procedures during a single procedure. Canaloplasty of Schlemm’s canal followed by trabeculotomy of the trabecular meshwork to reduce intraocular pressure in adult patients with primary open angle glaucoma.
  • ECP, the ciliary body of the eye, which creates fluid, is treated with a laser.

If you currently use medicated eye drops to manage glaucoma, ask your ophthalmologist if a MIGS procedure could be an option for you!
