Figure 1: (a) The cumulative percentage of preoperative and postoperative uncorrected distance visual acuity. Eyes with target of low myopia or whose preoperative corrected distance visual acuity <20/20 were not included in the postoperative calculation. (b) The change in corrected distance visual acuity after the operation. Most eyes had corrected distance visual acuity equal to or better than preoperative corrected distance visual acuity. Only 1.9% eyes lost two or more lines. (c) The attempted and achieved spherical equivalent. The black line is the slope of attempted versus achieved spherical equivalent for all eyes plotted in Figure 1c. Most eyes had slight tendency to undercorrection. (d) The postoperative spherical equivalent refraction. 91% eyes were within 0.5D and 95% eyes were within 1.0D. (e) The preoperative and postoperative refractive astigmatism. Most eyes had much improvement in refractive astigmatism after the operation. (f) The mean spherical equivalent at the baseline and 1, 3, 6, and 12 months after the surgery. Most eyes reach the stable refraction at the postoperative 1 month. (g) The postoperative contrast sensitivity. The mean contrast sensitivity of 3, 6, 12, and 18 cycles/degree mild decreased at postoperative 12 months with glare test off and on (P = 0.04 and 0.02, respectively)
