Continuous variables were expressed as mean (standard deviation). Categorical variables (Gender and Myopia Level) were expressed as frequencies (percentages).
S-Kappa, small Kappa group; L-Kappa, large Kappa group; MSE, mean spherical error; logMAR, logarithm of the minimum angle of resolution. P, p value from Chi-squared tests.
*for p value < .05, ** for p value < .01.
