Note: Success was defined as IOP > = 6 mm Hg and < = 21 mm Hg, with or without the use of anti-glaucoma medications, and without severe complications or reoperation. The differences in the success rates were compared between the two groups using the corrected chi-square test (two weeks, one month, and three months) and chi-square test (six months) and two-tailed Fisher’s exact test (12 months)
