^*: Significant difference among three groups.
One-way ANOVA tests or Kruskal-Wallis are indicated as mean ± SD.
AL = axial length, SD = standard deviation, D = diopter, ACD = anterior chamber depth, R₁ = flat axial corneal curvature, R₂ = steep axial of corneal curvature, logMAR = logarithm of the minimum angle of resolution, IOL = intraocular lens, SE = spherical equivalent.
