Intervention group: Continuing all preoperative aqueous suppressants immediately postoperatively, Control group: Receiving aqueous suppressants only as required postoperatively. Pearson Chi-square test was used for categorical variables, and Student t-test was used for continuous variables in statistical analysis. SD: Standard deviation, IOP: Intraocular pressure, AGV: Ahmed glaucoma valve
