IQR = interquartile range (i.e. the 25th to 75th percentile); MUST = Multicenter Uveitis Steroid Treatment.

^*Unless otherwise specified, P values compare the distribution of all primary categories excluding missing values.

^†Missing values: 1 preoperative intraocular pressure observation missing (1%) from implant group, and 2 observations missing time since uveitis at the preoperative visit in the implant group (2%).

^‡Based on a log transformation of time since uveitis onset at the preoperative visit.
