Comparison of subconjunctival microinvasive glaucoma surgery and trabeculectomy

Purpose To assess surgical success and the post-operative development of intraocular pressure between XEN45® gelstent, Preserflo® MicroShunt and trabeculectomy with mitomycin C. Methods Data from 105 eyes from 105 patients of matched cases with refractory open-angle glaucoma, who underwent surgery between January 2019, and August 2020, were evaluated. Patients underwent either stand-alone XEN gelstent insertion with Mitomycin C, stand-alone Preserflo with Mitomycin C or trabeculectomy with Mitomycin C. The primary outcome was the proportion of complete surgical success at 6 months post-operatively (i.e. intraocular pressure between 5mmHg and 18mmHg, no revision surgery, no loss of light per…
