Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The objective of this study was to evaluate the AqueSys XEN Implant \[XEN® Gel Stent (XEN45 Implant)\] for the treatment of moderate primary open angle glaucoma (POAG) participants when medications have failed to control intraocular pressure (IOP). Effectiveness was evaluated by comparing medicated preoperative IOP to postoperative values. Additionally, the number of topical IOP-lowering medications at screening were compared to the number of IOP-lowering medications at 1 year.
