Eligibility
Key inclusion criteria
- Glaucoma in the study eye.

1. Study eye diagnosed with open-angle glaucoma uncontrolled by medical therapy

2. Study eye that meet at least one of the following criteria:

- Failed one or more incisional intraocular glaucoma surgeries (e.g., glaucoma
filtering surgery or tube shunt) (a minimum of approximately 15 subjects
will be enrolled)

- Failed one or more cilioablative procedures (e.g., cryotherapy, cyclodiode
therapy)

- Have neovascular glaucoma

- Have any other condition (e.g., conjunctival scarring, uveitis) in which a
conventional incisional glaucoma surgery like trabeculectomy would be more
likely to fail than for a person with uncomplicated primary open-angle
glaucoma (OAG).

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.
Minimum age
45 Years
Maximum age
No limit
Sex
Both males and females
Can healthy volunteers participate?
No
Key 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.

Summary
Brief summary
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.
