Figure 1: Kaplan-Meier survival curve showing the proportion of eyes at 1, 3, 6, 9 and 12 months that underwent successful selective laser trabeculoplasty treatment in the setting of prior failed trabeculectomy. The definition of success is a) 3 mmHg IOP reduction, b) 20% IOP reduction, and c) 15% IOP reduction, with no further surgical or laser procedure and no additional glaucoma medications.
