  2. P 1: Mann-Whitney U test between the study and control groups at each time point
  3. P 2: Freidman test between median IOP at baseline and at different time points postoperative within each group
  4. P 3: Wilcoxon Signed Ranks test between median IOP at baseline and at 18th month postoperative within each group
