Statistical analysis
SECONDARY, IOL
The primary endpoint of this study was to examine the differences in BDCVA at distances of 0.3 and 0.4 m, photopic symptoms, and satisfaction for each distance vision between eyes with two types of IOLs. Differences in BDCVA for these distances were evaluated using the Mann-Whitney U test. Regarding the photopic symptoms, the proportions of patients with significant symptoms, including moderate-to-severe cases, were compared using the chi-squared test. The rates of satisfaction with near, intermediate, and far vision were analyzed in the same manner. As a secondary endpoint, binocular contrast sensitivity at far, 1 m, and 0.4 m were compared using t-test. Statistical significance was set at P < 0.05.For presenting the efficacy, the cumulative percentage of patients achieving binocular (20/x or better) at distances of 0.4 m (near), 0.7 m (intermediate), and 5 m (far) for each IOL were plotted [
