Fig. 2From: Comparative study of wave-front aberration and corneal Asphericity after SMILE and LASEK for myopia: a short and long term studyThe comparison of spherical aberration (SA, left y-axis) and corneal 6 mm-diameter-Q value (right y-axis) between SMILE and LASEK at pre-, three months and three years post-operatively. The horizontal axis corresponds to the time point of follow-up; the left vertical axis corresponds to spherical aberration (SA), the right vertical axis represents the Q value. * p < 0.05 = statistically significantBack to article page
