Figure 1From: Retrospective analysis of changes in the anterior corneal surface after Q value guided LASIK and LASEK in high myopic astigmatism for 3 years The mean refraction errors after aspheric LASIK and LASEK. Attempted spherical equivalent refraction versus achieved manifest refraction spherical equivalent (MRSE) in the Q-value guided LASIK group and LASEK group 3 years after surgery. LASIK: y = 1.07x + 0.15, R2 = 0.81; LASEK: y = 1.00x + 0.6, R2 = 0.91.Back to article page
