Two datasets were analyzed: All Eyes (ie, all eligible eyes) and First Surgery Eyes (ie, each patient’s first implanted eye). All Eyes were subgrouped by axial length (AL) and further analyzed. The main outcomes included paired differences in absolute prediction errors (APEs) between the ORA SYSTEM and BTK and differences in the proportion of eyes with APEs of ≤ 0.25 diopter (D) and ≤ 0.50 D.Results: 1067 eyes were analyzed, including 897 First Surgery Eyes. Significantly higher proportions of All Eyes had APEs of ≤ 0.25 D (P = 0.0128) and ≤ 0.50 D (P |
