What is 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

intraocular pressure (IOP

Intraocular pressure (IOP) is the fluid pressure inside the eye. Tonometry is the method eye care professionals use to determine this. IOP is an important aspect in the evaluation of patients at risk of glaucoma. Most tonometers are calibrated to measure pressure in millimeters of mercury (mmHg).

) in open angle glaucoma patients, thus preserving vision. It is also referred to as aqueous shunt surgery.

What is the success rate of Xen gel stent?

The overall complete success rate was 21.0–70.8% after 2 years using strict criteria originally designed to record success rate in filtration surgery. The incidence of complications vision-threatening was low at <1%. Conclusions: XEN gel stent was effective and safe for primary and secondary OAG.

How long does Xen gel stent surgery take?

What to expect with the Xen Gel Stent? The procedure usually takes one to two hours to complete, and the recovery time is minimal. Most patients are back to their usual routines within the first seven days after the procedure.

What can I expect after Xen 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.

Is Xen gel stent safe?

Conclusion: The gel stent effectively lowered IOP and IOP-lowering medication count over 3 years, with a predictable and acceptable safety profile, when implanted via the traditional ab-interno technique.

Can you feel a stent in your eye?

The iStent procedure adds about 15 extra minutes to the surgery. What will I feel during the surgery? You may see bright lights during the surgery, but should not feel pain. You may be asked to move your eyes in different direction for placing the stents in the eye.

How long do eye stents last?

The effect appears to be durable for at least 24 months. The Hydrus maintained significant reductions in medications and IOP.

How can I reduce the pressure in my eyes?

What is the best surgery for glaucoma?

The most common go-to surgical option for many doctors when it comes to glaucoma is laser surgery. Laser surgery is a treatment that you can choose to have at a clinic or your doctor's office. Its advantage is that it is a procedure that does not require overnight admission afterward.

Can a Xen stent be removed?

If the patient has elected to undergo a Xen replacement, the process is more direct and facile. The conjunctiva is already open during the revision, so I can easily remove the stent and place another one under direct visualization, without substantial additional manipulation of the eye.

Are you awake during eye stent surgery?

In this operation, the surgeon implants a tiny tube, or shunt, onto the white part of your eye. The tube helps extra fluid drain out of your eye, lowering your eye pressure. Usually, you'll be awake during this surgery — but you'll get numbing medicine and medicine to help you relax.

What are the disadvantages of stents?

damage to the artery where the sheath was inserted. allergic reaction to the contrast agent used during the procedure. damage to an artery in the heart. excessive bleeding requiring a blood transfusion.

How successful are stents for glaucoma?

In a U.S. clinical study, 68% of glaucoma patients who received iStent remained medication-free at 12 months while sustaining a target IOP of ≤ 21 mm Hg vs. only 50% of patients who underwent cataract surgery alone. iStent works like the stents used to prevent heart attacks and strokes.

What happens after a stent for glaucoma?

The stents create tiny channels that fluid can drain through, which helps to lower eye pressure. Following the surgery, most patients are able to stop or reduce the number of eye drops they use to treat their glaucoma.

Do eye stents need to be replaced?

Stents are made to be permanent and will continue to keep your artery open once they've been placed. However, stents don't cure the underlying condition that caused the buildup in your artery (atherosclerosis). You'll still need treatment to prevent future artery narrowing.

Is Xen gel stent FDA approved?

The FDA approved the Xen gel stent (Allergan) for the treatment of refractory glaucoma in patients who failed previous surgical treatment or in patients with primary open angle glaucoma who are refractory to maximum tolerated medical treatment.

What is the newest treatment for glaucoma?

Durysta is the first FDA approved sustained delivery bimatoprost implant approved for patients with open angle glaucoma and ocular hypertension. It is injected into the anterior chamber and settles in the inferior angle.

What is the newest surgery for glaucoma?

MIGS, or minimally invasive glaucoma surgery, is a relatively new approach to glaucoma treatment. Referring to a group of minimally invasive procedures, MIGS offers alternative surgical treatment options for glaucoma that pose fewer risks than traditional glaucoma surgeries.

Is eye pressure of 20 high?

While ocular hypertension isn't an eye disease in itself, it is an indication that you could develop glaucoma. Your eye pressure is measured in millimeters of mercury, expressed as mm Hg. Normal eye pressure is between 10 to 21 mm Hg. High intraocular pressure is greater than 21 mm Hg.

What is the best vitamin to take for glaucoma?

As previously mentioned, vitamin A and vitamin C are beneficial to our eyes, but vitamin E has also been shown to boost vision. Vitamin E can be found in wheat and cereal, seafood, avocados, nuts, egg yolks, and more. Zinc, Lutein and Zeaxanthin are also great for your eyes and can reduce your risk of glaucoma.

Is eye pressure of 50 high?

In general, pressures of 20-30 mm Hg usually cause damage over several years, but pressures of 40-50 mm Hg can cause rapid visual loss and also precipitate retinovascular occlusion.

Can you live 20 years after stents?

While the placement of stents in newly reopened coronary arteries has been shown to reduce the need for repeat angioplasty procedures, researchers from the Duke Clinical Research Institute have found that stents have no impact on mortality over the long term.

Can an eye stent become blocked?

Despite its proven effectiveness and safety profile, XEN gel stents (Allergan Plc, Dublin, Ireland) can become obstructed.
