The XEN Gel Stent implant is a new, minimally invasive surgical technique for many forms of glaucoma.
The Collamer implant is only 6 millimetres long and thinner than a human hair. It is made of collagen, which is biocompatible and very well tolerated. It functions as a minute tube, which can reduce pressure in the eye by up to 50% by draining excess fluid away.
The XEN Gel Stent is so small that it:
can be inserted without sutures
is not visible from the outside
is not noticed by the patient.
When can the implant be used?
The XEN Gel Stent implant is suitable if, for example,
You cannot tolerate drops that are used to lower your eye pressure
Treatment with drops doesn’t reduce your eye pressure enough, or your eye pressure fluctuates too much even if you use the drops
Your lifestyle makes it difficult for you to use eye drops regularly
The depth of the anterior chamber of the eye is not sufficient
Dr. med. Kristof Vandkerckhove interviewed by Isabel Walker, british journalist, about the XEN gel stent
Advantages of the XEN Gel Stent implant:
Significant and sustained reduction of intraocular pressure
No longer necessary to use eye drops
The surgical procedure is minor and very brief
Stable implant that stays permanently in place
Surgery and healing are usually painless
Stents can be replaced if necessary
Further surgery of the affected eye is still possible
Insertion is possible even if glaucoma surgery has already been carried out
Possible risks and complications:
The procedure is usually free of complications
Cysts may form in very rare cases, resulting in brief follow-up medication as an outpatient
Strict compliance with intensive use of eye drops for four weeks after the intervention is essential in order to ensure straightforward healing.
No serious complications that would lead to loss of vision have occurred so far.
Implantation & function of the XEN Gel Stent
After a very small 2 mm incision in the cornea, the implant is inserted with a disposable injector into the subconjunctival space, where it remains permanently. The injector is withdrawn and the incision seals up by itself. The procedure takes place on an outpatient basis with local anaesthetic and moderate sedation, and lasts about 15 minutes. Follow-up appointments are made after the intervention in order to monitor the healing process. The stent implant connects the anterior chamber with the subconjunctival space, so that fluid can flow from the anterior chamber of the eye into the veins of the conjunctiva, from where it is carried away into the body.
