Safety and Effectiveness of PreserFlo and XEN Stents With or Without Amniotic Membrane in Glaucoma Surgery

Arm 2: Glaucoma Surgery with Amniotic Membrane Participants undergo glaucoma surgery with either a PreserFlo MicroShunt or a XEN Stent, as determined by the treating surgeon. In this group, the implanted stent is covered with an amniotic membrane patch to reduce postoperative scarring and improve long-term outcomes. Follow-up visits are scheduled as per standard of care for glaucoma surgery (up to 12 months).

Arm 1: Glaucoma Surgery without Amniotic Membrane Participants undergo glaucoma surgery with either a PreserFlo MicroShunt or a XEN Stent, as determined by the treating surgeon. No modifications are made to the procedure. Follow-up visits are scheduled as per standard of care for glaucoma surgery (up to 12 months).
