*Any eye undergoing a repeat procedure was considered a failure for each of these definitions. 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 in statistical analysis. IOP: Intraocular pressure
