  1. Generalized linear model was adopted for comparison of preoperative and early postoperative factors (i.e. refraction, axial length and topographic parameters) between groups after adjusting for age, sex, and preoperative cycloplegic refractions.
  2. aOR adjusted odds ratio, AXL axial length, CCT central corneal thickness, CD corneal diameter, CI confidence interval, HOA higher order aberration, N number, SA spherical aberration, SE spherical equivalent, TCRP total corneal refractive power, UCVA uncorrected visual acuity.
  3. *Denotes a significant difference between groups.
