Efficacy and Safety of Primary Glaucoma Device Implantation Surgery in Exfoliative Glaucoma: A Retrospective Consecutive Case Series

Figure 2

Kaplan–Meier survival analysis. The graph shows the success rates of primary glaucoma device implantation surgery according to criteria 1 (IOP ≤ 18 mmHg and an IOP reduction of 20% with 1 or no medication), 2 (IOP ≤ 15 mmHg and an IOP reduction of 25% with 1 or no medication) and 3 (IOP ≤ 12 mmHg and an IOP reduction of 30% with 1 or no medication) in XFG.
