Kaplan–Meier survival plot based on intraocular pressure (IOP) ≥ 21 mmHg without (a, complete success) or with (b, qualified success) glaucoma eye drops for the Ex-PRESS® group (14 patients, solid line) and the trabeculectomy group (30 patients, dashed line). The probability of qualified success of trabeculectomy was significantly higher than that of Ex-PRESS® (P = 0.018)
