D = Diopters; group 1 = small-incision lenticule extraction for myopia and myopic astigmatism ≤10 D; group 2 = small-incision lenticule extraction for myopia and myopic astigmatism > − 10 D; LogMAR = logarithm of the minimal angle of resolution; UDVA = uncorrected distance visual acuity; CDVA = Corrected distance visual acuity; SD = Standard deviation
