Stacked histogram analysis comparing the percentage of eyes within given prediction error ranges relative to the preoperative BUII. The formulas were sorted by the proportion of eyes within ± 0.50 D in descending order. The formulas with the highest proportion of AEs < 0.5D were the BTK-K (71.15%), EVO-TK (69.23%), and Masket-K (67.31%).
