The refractive error=postoperative spherical equivalent power − preoperative target refraction.
The refractive error was recorded at 6 months after surgery.
For the refractive error, the Mann-Whitney U test showed a significant difference between NR81K and CZ70BD groups and between All IOLs and AN6KA.
For the anterior chamber depth, Kruskal-Wallis test showed no significant difference between NR81K, CZ70BD and AN6KA groups.
Data are mean±SD.
