(Minimum - Maximum)	(23.5–78.5)	(6.0–27.5)	(8.0–28.0)	(12.0–31.5)	(14.5–27.0)	(12.0–30.0)

Note: IOPs before surgery and at two weeks, one month, three months, six months and 12 months after surgery were determined using an applanation tonometer (mean of 9 am and 4 pm measurements). Differences in IOPs at various time points throughout follow-up were compared between the two groups using the t test
