What is Glaucoma Surgery?

Glaucoma Surgery is needed to reduce pressure in the eyes by opening blocked drainage angles or creating a new opening that fluid can flow through to leave the eye. In some cases surgery may be done to relieve pain caused by glaucoma.

Traditional surgical options for glaucoma (trabeculectomy and tube shunt implantation) have a substantial number of potential complications, including hypotony, hyphema, bleb leakage, bleb infection, and endophthalmitis.
What is minimally invasive glaucoma surgery? Minimally invasive glaucoma surgery (MIGS) provides intraocular pressure reduction for patients with mild-to-moderate glaucoma with a better safety profile than traditional incisional glaucoma surgery. These devices and procedures are often combined with cataract surgery.

The CyPass Micro-stent is a fenestrated micro-stent comprised of biocompatible polyimide material and is inserted into the supraciliary space during cataract surgery, thereby creating a permanent conduit between the anterior chamber and the supraciliary space. By doing so, the device enables aqueous drainage through the uveoscleral pathway.

Glaucoma Causes

Glaucoma is a condition that causes damage to your eye's optic nerve and gets worse over time. It's often linked to a buildup of pressure inside your eye. Glaucoma tends to be inherited and may not show up until later in life.

The increased pressure, called intraocular pressure, can damage the optic nerve, which transmits images to your brain. If the damage continues, glaucoma can lead to permanent vision loss. Without treatment, glaucoma can cause total permanent blindness within a few years.

What You Can Do

Minimally invasive glaucoma surgery (MIGS) is a procedure that is combined with cataract surgery for patients with mild to moderate glaucoma. These procedures have far fewer side effects than traditional glaucoma surgery and are covered by most private and government insurance plans. During cataract surgery a small device (iStent or CyPass) is placed in the drainage pathways of the eyes creating a permanent opening for the fluid in the eye to drain in the surrounding blood vessels. This reduces eye pressure with less need for glaucoma drops. The procedure is painless and typically ads less than 5 minutes to the cataract surgery time
