About this trial

Multicentric evaluation of best corrected visual acuity of the XEN implant versus classic trabeculectomy in open angle glaucoma subjects

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

Diagnosis of open angle glaucoma (Primary open angle glaucoma, Pseudoexfoliation glaucoma, Pigmentary dispersion glaucoma)

Clinically eligible for both surgeries (Trabeculectomy and XEN) on the discretion of the surgeon (area of healthy, free and mobile conjunctiva in the superior nasal target quadrant)

VA logMAR ≤ 1 (VA dec ≥ 0.1)

Trabecular meshwork must be visible (with Shaffer angle grade > 1 in the target quadrant)

Disqualifiers

Clinical significant cataract

Subject has had prior cataract surgery in study eye ≤ 1 months (count to operation)

Subject has had prior (incisional) glaucoma surgery (XEN, trabeculectomy, viscocanalostomy, canaloplasty, shunts of any type, collagen implants, etc.). Prior iridotomy is acceptable.

Phacic Angle Closure Glaucoma
