Glaucoma—the silent thief of sight. It is a condition associated with pressure in the eye and characterized by damage to the optic nerve with slow vision loss that can lead to blindness. Glaucoma affects two million Americans, and half of those people are unaware they even have the disease. Glaucoma can run in families.

Swagel Wootton Eye Institute’s team of glaucoma specialists are here to serve you and offer a variety of glaucoma treatment options with the goal of relieving symptoms and preventing further damage or loss of sight. We offer same-day appointments with our glaucoma specialists in Mesa and Chandler.

While there is currently no cure for glaucoma, there are many treatment options that can prevent patients from losing vision.

How is Glaucoma Treated?

Glaucoma treatment ranges from eyedrops to surgery.

For each patient, a personalized treatment and follow-up plan will be discussed and organized with a Swagel Wootton Eye Institute glaucoma specialist. The goal of glaucoma therapy is to preserve the patient’s present level of vision and to prevent further vision loss.

Your personalized treatment plan will depend on the type of glaucoma diagnosed, the degree to which the glaucoma has progressed, your underlying risk factors, as well as other variables.


If you’ve been managing your glaucoma symptoms with medication, and are also in need of cataract surgery, iStent Trabecular Micro-Bypass may be an ideal option for you.

iStent® is a tiny implant that’s helped thousands of people with glaucoma successfully manage their intraocular pressure and reduce or eliminate their need for eye drops. By taking advantage of this once-in-a-lifetime opportunity to address your glaucoma during cataract surgery, you can address both of these conditions at the same time.


CyPass Micro-Stent has been called the latest advance in glaucoma patient care. The procedure is for patients with mild to moderate primary open-angle glaucoma.

CyPass helps patients reduce or possibly eliminate the need for eye drops to control their intraocular pressure. Like iStent, the procedure is performed concurrently with cataract surgery and IOL implantation. Approximately 70% of CyPass® patient are able to reduce or eliminate their glaucoma drops and still achieve their target IOP.

Your Swagel Wootton Eye Institute surgeon will help you determine whether the iStent and CyPass device may be more effective for you.

XEN® Gel Stent

XEN Gel Stent is a surgical implant designed to lower high eye pressure in open-angle glaucoma patients where previous surgical treatment has failed and/or medications alone were insufficient (also known as refractory glaucoma).

The XEN Gel Stent creates a small channel in the eye to drain fluid and help lower eye pressure. The XEN Gel Stent is tiny (no longer than an eyelash!) and it’s placed just under the clear membrane that covers the white of the eye.

The stent is designed to stay in the eye permanently. You may not need to use eye drops after the XEN procedure. Your Swagel Wootton Eye Institute doctor will determine your need for eye drops after the XEN procedure.


SLTSelective Laser Trabeculoplasty (SLT) is a laser-assisted procedure that treats intraocular pressure caused by open-angle glaucoma. In patients with open-angle glaucoma, the trabecular meshwork (drainage tissue in the eye) does not allow for adequate outflow, causing intraocular pressure (IOP) which needs to be managed with medication or surgical intervention. Unregulated IOP can lead to blindness.

SLT is one of many options to address IOP in open-angle glaucoma patients. Successful SLT treatment can last anywhere from 1 to 5 years and patients can undergo SLT surgery multiple times as needed. SLT may replace the need for glaucoma medication in some patients, but additional medications may still be needed in some cases. Your Swagel Wootton Eye Institute doctor will work closely with you to determine the best treatment plan.


Laser Peripheral Iridotomy (LPI) is a laser treatment used for narrow angle glaucoma and acute angle closure glaucoma. With these conditions, the part of the eye responsible for draining fluid from the eye becomes narrow, causing increased intraocular eye pressure (IOP). This can happen suddenly or may occur over time.

During LPI treatment, a laser is used to target the narrow angles between the iris and cornea in an attempt to widen them and increase fluid flow, allowing the eye to better regulate intraocular pressure.


Cyclophotocoagulation (cyclo-photocoagulation) is an alternative glaucoma treatment most often used when glaucoma medication and other surgical treatment options do not lower intraocular pressure (IOP) as much as desired or required. These glaucoma cases are often referred to as ‘refractory,’ or stubborn and resistant to treatment.

Cyclophotocoagulation is a surgical laser procedure that targets the source of IOP directly. CPC may be repeated if the desired eye pressure is not achieved. ECP is performed endoscopically.
