Data are expressed as means ± standard deviations (range). † p values are calculated using the mixed-effects regression model. ‡ p values are calculated using the paired t-test between preoperative and respective time period values. Abbreviations: µLOT, microhook trabeculotomy; SD, standard deviation.
