SMILE and Wavefront-Guided LASIK Out-Compete Other Refractive Surgeries in Ameliorating the Induction of High-Order Aberrations in Anterior Corneal Surface

Figure 4

Comparison of the vertical coma changes in four groups. Comparison of the induced vertical coma between wavefront-guided LASIK and both femtosecond laser-assisted LASIK ( value is 0.015) and small incision lenticule extraction ( value is < 0.001). Positive and negative values indicate an average positive or negative shift, respectively, in vertical coma relative to preoperative values.
