Comparison of subconjunctival microinvasive glaucoma surgery and trabeculectomy.

No statistically significant differences were found between trabeculectomy, XEN45® gelstent implantation and Preserflo® MicroShunt implantation regarding surgical success after 6 months. Yet reduction in intraocular pressure was significantly higher in the trabeculectomy group. However, all three interventions resulted in sufficiently low post-operative intraocular pressure and may therefore be considered individually for glaucoma treatment.
