Study Summary

This trial is looking at two different ways to do glaucoma surgery, to see which one works better. They will compare how well each method lowers eye pressure, how many medications each method requires, and what side effects occur.

Who is the study for?
This trial is for adults over 18 with uncontrolled glaucoma despite maximum medical treatment. Participants must be in good health, able to follow post-op instructions, and attend scheduled appointments. Excluded are those with recent cancer chemotherapy, participation in other trials within 30 days, certain eye conditions or surgeries, severe allergies to protocol medications or XEN components, systemic corticosteroid use within 30 days (except chronic use), pregnant or nursing women not using contraception.Check my eligibility
What is being tested?
The study compares two surgical techniques for implanting a XEN gel microstent to treat glaucoma: the traditional ab interno (inside the eye) approach versus an ab externo (outside the eye) method performed at the slit lamp. Success rates will be measured by changes in intraocular pressure, medication needs, additional procedures needed and adverse events.See study design
What are the potential side effects?
Potential side effects may include complications from surgery such as infection or inflammation of the eye, increased intraocular pressure if stent fails to function properly, discomfort or bleeding at the implantation site and possible need for additional glaucoma medications or surgeries.

Trial Design

2Treatment groups
Experimental Treatment
Group I: Ab interno techniqueExperimental Treatment1 Intervention
Ab Interno is traditional method of stent XEN implantation, where the device will injected through a small corneal incision that closes with the preloaded XEN injector.
Group II: Ab externo techniqueExperimental Treatment1 Intervention
The ab externo approach does this without any incision, less invasive, and the implant is directly injected through the conjunctiva into the anterior chamber of the eye. Both methods create a new way out through the subconjunctival space, which is the traditional target of trabeculectomy.
