Two-year outcomes of minimally invasive XEN Gel Stent implantation in primary open-angle and pseudoexfoliation glaucoma.

The XEN® Gel Stent is an efficacious minimal invasive glaucoma surgery for primary open-angle and pseudoexfoliation glaucoma, resulting in significant reduction of IOP and a reduction in glaucoma medications from baseline in two-third of treated patients with 2-year follow-up. Frequent follow-up examinations were mandatory to identify early and late bleb failure and additional needling procedures were necessary to reestablish aqueous flow.
