Text: Eyes undergoing both treatments had improved best-corrected visual acuity (WFG : mean, 0. 05 [95 % CI, 0. 03-0. 07] ; WFO : mean, 0. 04 [95 % CI, 0. 02-0. 06]) and less sphere (WFG : mean, -4. 79 [95 % CI, -5. 31 to -4. 26] ; WFO : mean, -4. 61 [95 % CI, -5. 18 to -4. 03]), cylinder (WFG : mean, 0. 66 [95 % CI, 0. 49-0. 82] ; WFO : mean, 0. 52 [95 % CI, 0. 35-0. 69]), and spherical equivalents (WFG : mean, -4. 45 [95 % CI, -4. 99 to -3. 91] ; WFO : mean, -4. 34 [95 % CI, -4. 92 to -3. 76]) (P <. 001) but higher levels of spherical aberration (WFG : mean, -0. 11 [95 % CI, -0. 15 to -0. 06] ; WFO : mean, -0. 11 [95 % CI, -0. 14 to -0. 07]) (P <. 001) and higher-order root-mean-square aberrations (WFO : mean, -0. 07 [95 % CI, -0. 12 to -0. 02] ; WFO : mean, -0. 12 [95 % CI, -0. 17 to -0. 70]) (P =. 005 in WFG eyes and P <. 001 in WFO eyes) at 12 months compared with preoperative measurements.
