aPreoperative and postoperative medication burden outcomes data were analyzed using Kruskal-Wallis tests. Pairwise comparisons were conducted following significant Kruskal-Wallis test results using Dunn’s test. AC = anterior chamber; S = sulcus; PP = pars plana; N = Number of eyes; SD = standard deviation.
