BackgroundThis study compares the clinical outcomes of femtosecond laser small-incision lenticule extraction (SMILE) for the correction of myopia and myopic astigmatism greater than -10 D, and-10 D or less respectively.Methods60 eyes/patients were equally selected into group 1 (myopia and myopic astigmatism of -10 D or less) and group 2 (myopia and myopic astigmatism of over -10 D), both of which were treated with SMILE. Visual and refractive outcomes, corneal higher-order aberrations, and Bowman's layer micro-distortions were evaluated preoperatively, 3months, and 6months postoperatively.ResultsLogMAR corrected distance visual acuity (CDVA) of group 1 and group 2 was -0.0690.047 and-0.053 +/- 0.073 6months postoperatively (P=0.48). 100% eyes in group 1 and 97% in group 2 were within 1 D of targeted correction (P=0.45). Meanwhile, 100% eyes in group 1 and 97% in group 2 had an uncorrected distance visual acuity of 20/25 or better (P=0.20). Changes in corneal higher-order aberrations root mean square, coma, and trefoil were similar between the two groups but spherical aberration was higher in group 2 (P -10 D and-10 D. Refractive outcomes showed slightly under-correction in higher myopic eyes. Higher myopic treatment tends to induce more spherical aberrations. Micro-distortions had no impact in visual and refractive outcomes.
