- The defocus curves and the area-of-focus metric of the 2 groups. A) The defocus curves of the 2 groups; B) the area-of-focus metric of the 2 groups. The near area was between -4.0 D and -2.0 D, corresponding to the range from 25 cm to 50 cm; the intermediate area was between -2.0 D and -0.50 D, corresponding to the range from 50 cm to 2 m; the distance area was defined as -0.50 D to +0.50 D, corresponding to the range beyond 2 m. D: diopter, VA: vision acuity, logMAR: minimum angle of resolution

↵^* n represented the number of eyes followed up after surgery (one case in group A was lost to follow-up, and there were 2 cases of fundus disease in group B not found before the operation. These 3 patients were not included in the postoperative statistical analysis).
↵⁺ All visual acuity was expressed in logMAR,
