ELIMINATE OR REDUCE YOUR NEED FOR GLAUCOMA DROPS WITH Micro Invasive Glaucoma Surgery MIGS is a new treatment option available in glaucoma therapy that is a safe and effective way to improve the eye’s natural fluid outflow.

The MIGS procedures are designed to reduce intraocular eye pressure by improving aqueous outflow through the natural physiologic pathway as well as preserving important eye tissue and future treatment options that could help maintain long-term vision.


While standard glaucoma surgeries are often very effective at lowering eye pressure and preventing progression of glaucoma they are all considered a major surgery. They often have a long list of potential complications. MIGS were designed to reduce some of the potential complications associated with standard glaucoma surgeries.

How it Work?

MIGS safely and effectively improves the eye’s natural fluid outflow by creating a direct path for fluid to flow between the fluid-filled chamber of the front of the eye and the major collector channel that directs fluid out of the eye bypassing the meshwork of tissue through which the fluid normally flows.

Types of MIGS

There are several designs of MIGS devices which can be divided into several categories:


Is the use of microscopic-sized tubes which are inserted into the eye to drain fluid from the inside of the eye to the outer membrane of the eye (conjunctiva). There has recently been improvement in the design trabeculectomymaking the surgery safer.

Trabecular Surgery

In most cases restriction of fluid drainage happens at the trabecular meshwork. The trabecular meshwork is responsible for draining fluids out of the eye naturally. In trabecular surgery, the MIGS device penetrates through the trabecular meshwork without damaging any other tissues in the eye’s drainage pathway; this allows trapped fluid to bypass out of the eye as it was naturally intended.

Suprachoroidal Shunts

This technology uses tiny tubes with small internal openings to connect the front of the eye to the space between the retina and the wall of the eye. This effectively allows the drainage of fluid from the eye and reduces the pressure which causes damage to the eye.

Latest Laser Procedures

Generally, laser procedure to treat glaucoma symptoms are reserved for advanced glaucoma cases. These laser procedures are designed to reduce the fluid-forming in the eye by targeting the tissue (ciliary body) that creates the fluid. However, recent developments to the laser treatment procedures have proven useful even for moderate glaucoma cases.

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.
