AGM = antiglaucoma medication; Phaco = phacoemulsification; GATT = gonioscopy‑assisted transluminal trabeculotomy. The P-values in the rightmost column represent the statistical comparisons of the Phaco-GATT and GATT-Phaco groups at each time point. The P-value in the last row represents the within-group comparison baseline with 12 months
