  1. M, male; F, female; BCVA, best-corrected visual acuity; IOP, intraocular pressure; SE, spherical equivalent; AL, axial length; N/A not applicable.
  2. Values are presented as mean ± standard deviation (count).
  3. P values were yielded by student t-test for comparing continuous values.
  4. P values were yielded by Chi-square statistics for comparing categorical values.
  5. *Bold values indicate statistically significant differences (P < 0.05).
