Comparative Outcomes of the Molteno3 and Baerveldt Glaucoma Implants

To compare outcomes between 2 nonvalved glaucoma drainage devices (GDDs) used to treat refractory glaucoma or in patients with neovascular/uveitic glaucoma likely to be poorly responsive to less aggressive therapies. Retrospective, nonrandomized, multicenter comparative study. A total of 117 eyes from 117 patients. Retrospective chart review of patients who underwent implantation of the Baerveldt (BGI) (Abbott Medical Optics, Abbott Park, IL) or the Molteno3 glaucoma implant (MGI) (Molteno Ophthalmic Limited, Dunedin, New Zealand). Noninferiority of the MGI versus the BGI was tested with Cox and mixed-effects regression models. Interventions in each group were analyzed with chi-square tests. The primary outcome was time until device failure, defined as intraocular pressure (IOP) >21 mmHg or a reduction
