Change From Baseline in Mean Intra Ocular Pressure (IOP) in Study Eye at Day 14: 8 Ante Meridiem (AM) (0 Hour)
8 AM on Baseline (Day -8), 8 AM on Day 14 (0 Hour)

IOP was measured using Perkins applanation tonometer at Day -8, Day 14 and using standard Goldmann applanation tonometer at eligibility visit. IOP was measured in both eyes, and the eye with higher IOP reading across eligibility visit and Day -8 visit was referred as 'study eye' for efficacy assessment. If both measurements were equal, right eye was selected as study eye. IOP was measured twice in same eye, and if difference between 2 measurements was less than or equal to 2 millimeter of mercury (mmHg), mean of the 2 readings was recorded as the IOP at that time point. If the difference between 2 readings was greater than 2 mmHg, a third consecutive reading was taken and the median IOP was recorded as the IOP at that time point. Mean IOP was reported as the average of individual participants' mean or median IOP values. Change from baseline in IOP = baseline IOP - post-baseline IOP. Change was calculated using the value at 8 AM on Day -8 as baseline for 8 AM value on Day 14.
