Comparison of the postoperative visual quality after SMILE and LASEK for high myopia: a 1-year outcome

Figure 2. Comparison of (A, B) photopic and (C, D) scotopic contrast sensitivity between the (A, C) laser-assisted subepithelial keratomileusis (LASEK) and the (B, D) small incision lenticule extraction (SMILE) groups at all spatial frequencies (6.3° to 0.7°), preoperatively and postoperatively. Horizontal axis corresponds to visual angle of target size (degree). Vertical axis corresponds to log10 contrast sensitivity
