XEN® Gel Stent

Xen Gel Stent logo

Glaucoma is one of the most common causes of blindness in the world — this prevalent eye disease affects over sixty billion people globally. Fortunately, advanced glaucoma treatment options are available to lower eye pressure and prevent glaucoma-related vision loss.

Eye Physicians of Long Beach, CA is proud to offer the XEN® Gel Stent, a state-of-the-art, minimally invasive procedure for glaucoma patients. The XEN® Gel Stent has been shown to lower intraocular eye pressure and reduce the use of prescription medication in open-angle glaucoma patients. Keep reading to learn more.

What is the XEN® Gel Stent?

The XEN® Gel Stent is a small surgical implant designed for use in minimally invasive glaucoma surgery. The procedure helps drain fluid and reduce intraocular pressure (IOP) in open angle glaucoma patients, thus preserving vision. It is also referred to as aqueous shunt surgery.

How Does It Work?

The XEN® Gel Stent is a small, tubular implant about the length of an eyelash. When placed just under the surface of the eye, the stent acts as a drainage device that channels fluid from the anterior chamber of the eye into an area called the subconjunctiva.

As fluid leaves the eye, intraocular eye pressure is reduced. Lowering eye pressure levels can protect against optic nerve damage and permanent vision loss.

How is the XEN® Gel Stent Different From Other Glaucoma Surgeries?

The XEN® Gel Stent is considered to be a hybrid between traditional glaucoma surgery, such as a tube shunt, laser trabeculoplasty, or trabeculectomy, and minimally invasive glaucoma surgery (MIGS).  Many surgeons believe the procedure to be safer than traditional glaucoma surgeries because it takes less time to perform, is less invasive, involves a shorter recovery time, and results in fewer complications. Additionally, the XEN® Gel Stent procedure can be performed as a stand-alone procedure or at the same time as cataract surgery.

The XEN® is also unique from other stents because it softens and becomes flexible when inserted into the eye. Another advantage is that it is made of non-silicone material, which can reduce inflammatory reactions and lower the risk of a blocked drainage system.

What Happens During the Procedure?

First, your eye doctor will administer local or topical anesthesia, so you feel no pain. During surgery, your doctor will make a small incision on the surface of the eye. The XEN® Stent will then be inserted with an injector that is preloaded with the stent. Surgery typically takes 1 to 2 hours, and recovery is quick — most patients are back to their normal routine within a week or less.

How Successful is the XEN® Gel Stent?

In clinical trials, XEN reduced IOP in nearly all patients. The majority of participants did not require medications after 12 months of surgery, and most others had safe IOP ranges with reduced medicated eyedrops.

What Are The Complications?

XEN stent surgery is considered very safe, and the complication rates are low compared to some other eye fluid drainage procedures. However, there are risks associated with every glaucoma surgery. Potential complications include:

Is the XEN® Gel Stent right for me?

The XEN® Gel Stent was approved by the FDA in 2016 for patients with:

It is assumed that these patients require surgery because they have already been unsuccessful in using medicated eyedrops alone to manage eye pressure levels.
