Cataract surgery, if planned, may be performed before XEN implantation. Following intraocular lens (IOL) implantation, miotic drugs may be used to facilitate XEN implantation. The intended area of placement in the supero-nasal quadrant, which is 3 mm from the limbus, is marked.
What are the advantages of Xen implant?
Xen Implant has some advantages over traditional surgeries such as trabeculectomy and tube shunt surgeries: Soft and flexible when wet. Minimally invasive, pre-loaded injector. Shorter surgical and recovery times. Potentially fewer side effects, e.g. prevention of chronic hypotony by an intrinsic flow-limiting design.
Is glaucoma a risk factor for blindness?
Glaucoma is a leading cause of overall blindness, and the number one cause of irreversible blindness, both in the United States and worldwide. Elevated intraocular pressure (IOP) is a major risk factor for the development and progression of glaucoma.
Is IOP reduction good for glaucoma?
The decrease in quality of life associated with glaucoma can be profound and may occur earlier than previous thought, highlighting the importance of early diagnosis and treatment. Reduction of IOP is the only proven method to prevent and treat glaucoma.
What is Xen gel?
XEN GEL Implant (Allergan Inc., CA, USA) is a 6-mm hydrophilic tube of collagen-derived gelatin cross-linked with glutaraldehyde, which is noninflammatory and causes minimal extraocular fibrotic or vascular response to the implant material. The XEN decreases IOP by creating a permanent drainage shunt from the anterior chamber (AC) to the subconjunctival space through a scleral channel. The device hydrates within 1-2 minutes of contact with aqueous humor, bending and conforming to tissue. This flexibility mitigates many of the issues seen with synthetic materials such as migration, erosion and corneal endothelial damage.
What is the best patient for Xen?
The most suitable patients for Xen implantation are: Patients with uncontrolled glaucoma, primary open-angle glaucoma, and pseudoexfoliative or pigmentary glaucoma with open angles that are un responsive to maximum tolerated medical therapy.
Is Xen needling safe?
Prospective studies have reported needling rates as high as 46.2% within the first 12 months. XEN needling has been demonstrated to be relatively safe and effective. However, there are reports of XEN fractures and amputations caused by needling. One case series of XEN fractures after needling concluded that because XEN is composed of flexible gelatin, the device can be damaged relatively easily during the bleb needling process.
Does Xen help with glaucoma?
Although no surgery can cure glaucoma forever or reverse vision loss, Xen is an effective surgery that can slow or stop the progression of glaucoma by lowering the pressure in your eye. Xen is less invasive compared to traditional glaucoma surgery (trabeculectomy) and has a quicker recovery.
What happens when you have Xen?
Once the Xen has been implanted, fluid begins to leave the eye more easily. This escaping fluid raises the conjunctiva (clear membrane covering the white part of the eye) creating a “filtering bleb.”. This “bleb” or bubble on the surface of the eye is usually under the upper eyelid and not visible without raising the upper lid.
Can you reduce eye drops after glaucoma surgery?
Sometimes patients are able to reduce the number of eye drops they are taking. Even if you are taking the same glaucoma medications after the procedure, the surgery is a success if your pressure is lower.
How long does it take to return to work after eye surgery?
Depending on your job and your other eye, you should be able to return to work within a few days to a few weeks. Limitations in physical activities at work may be needed. After surgery, your eye may be sore, and it may feel like there is something in it, like an eyelash.
Where is the Xen placed?
The Xen is loaded in a specific inserter and is placed at the top part of the eye. One end is inside the eye and the other end is under the conjunctiva. So it drains the fluid form anterior part of the eye to the space under the conjunctiva.
Do you have to have follow up appointments for glaucoma?
It is very important that you keep your follow up appointments so your surgical team can monitor the pressure and the healing, watch for complications, and make sure that your eye stays on track for a positive result. The need for glaucoma eye drops is usually reduced if not eliminated after surgery.
Can you see bright lights during surgery?
You may see bright lights during the surgery, but should not feel any pain. You will be discharged with a clear plastic shield over the operated eye. An adult will need to drive you home since you received sedative medications.
What is Xen gel stent?
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—about the length of an eyelash—and it’s placed just under the conjunctiva, which is a clear membrane that covers the white of your eye.
What happens after eye surgery?
The most common side effects after surgery include reduction of vision, eye pressure becoming too low, an increase in eye pressure, and need for an additional surgical procedure in the eye to release scar tissue (needling) around the implant under the conjunctiva. Talk to your doctor about other possible side effects.
How does a shunt help with glaucoma?
This is accomplished by creating a new opening for fluid to drain from the eye — or, by implanting a shunt to help drain the fluid.

Can glaucoma surgery cause vision loss?
Vision Loss. In the short term after your operation, glaucoma surgery temporarily disrupts your vision. It is important to understand that permanent vision can be reduced, or even, in very rare instances, totally lost as a result of any of these glaucoma operations; however, vision loss is not a common permanent side effect.
Can cataracts be repaired with glaucoma?
Cataract formation most likely will be accelerated by glaucoma surgery, but luckily cataracts are fairly easy to fix surgically . Sometimes glaucoma surgeries are combined with cataract surgery if your ophthalmologist feels that the cataracts are having a moderate to significant impact on your vision. However, for some glaucoma surgeries it is better to perform the glaucoma surgery alone and address the cataract later in a second operation.
Is glaucoma permanent?
Although glaucoma surgery can prevent further vision loss and on rare occasions even improve vision, damage that has already occurred due to glaucoma is considered permanent and not yet reversible via medication, laser surgery, eye stents, or MIGS.
OVERVIEW
Surgical procedures for glaucoma have been evolving over the past 100 years. Over the past 25 years, we have made large strides in improving surgical techniques and outcomes. Glaucoma surgery is intended to lower the intraocular pressure (eye pressure.) By lowering the eye pressure, we attempt to slow down progression of the disease.
WHAT SHOULD I EXPECT FROM GLAUCOMA SURGERY?
Glaucoma surgery attempts to lower eye pressure by various methods. These methods will be clearly described in the following sections. Regardless of the method used, it must be clear to patients that it takes on average 3 to 6 weeks to recover from surgery.
IS THERE PAIN DURING OR AFTER GLAUCOMA SURGERY?

IS THERE BLURRY VISION AFTER GLAUCOMA SURGERY?
Patients may experience blurry vision for the first 3 to 6 weeks following surgery. The blurry vision can be very upsetting to patients who do not expect this. However, if the 3 to 6 week recovery period is clearly explained and emphasized to the patient, many patients do not have difficulty during this period.
WILL I NEED EYEDROPS AFTER GLAUCOMA SURGERY?
Most patients do not require “glaucoma” eye drops after surgery. They do, however, require three types of post-operative eye drops for the first 2 to 3 months following surgery. The types of drops needed include: 1. An antibiotic 2. An anti-inflammatory (usually prednisone) 3.
WHY DO WE PERFORM GLAUCOMA SURGERY?
Glaucoma surgery is an effective method of controlling the disease. The surgeries, however, DO NOT “cure” glaucoma. The goals of surgery are to lower the pressure so as to protect the optic nerve from continued damage. The surgeries do not restore sight which has already been lost. The surgeries do not improve vision.
