About
Glaucoma is the second most common cause of blindness in the world, second only to cataracts. This study will assess how safe and effective a glaucoma gel stent is when implanted using the ab externo approach. Adverse events and intraocular pressure will be assessed.
XEN45 is an approved device for the treatment of glaucoma implanted using the ab interno approach (inside the eye). XEN45 implanted using the ab externo approach (outside the eye) is being studied in this study. Approximately 65 participants aged 45 years or older with open-angle glaucoma will be enrolled in this study at approximately 22 sites in the United States.
All participants will receive XEN45 implanted using the ab externo approach on Day 1 and will be followed for 12 months.
Participants will attend regular visits during the study at a hospital or clinic. The safety and effect of the gel stent on your glaucoma will be checked by medical assessments and eye examinations.

Inclusion and exclusion criteria
Inclusion Criteria:
Glaucoma in the study eye.
Study eye diagnosed with open-angle glaucoma uncontrolled by medical therapy
Study eye that meet at least one of the following criteria:
Note: To allow for a subgroup of participants who only have OAG uncontrolled by medical therapy (non-refractory glaucoma), a maximum of 10 participants who meet only criterion a (and not b) will be enrolled.
Exclusion Criteria:
A lack of healthy conjunctiva showing free mobility (free of scarring or evidence of prior surgery) in the target area.
Excessive intraoperative bleeding, such that visualization in the study eye is impaired.
Any anatomy or finding in the study eye that limits the investigator's ability to visualize the anterior chamber, angle, or target area of the conjunctiva.
Other surgical complication that in the opinion of the investigator could impede proper placement of the Gel Stent.
