Note. P1: P value of the difference in the visual quality parameters before surgery and one day after surgery; P2: P value of the difference in the visual quality parameters before surgery and one week after surgery; P3: P value of the difference in the visual quality parameters before surgery and three months after surgery. ∗P < 0.05: significant difference. MTF: modulation transfer function; OSI: objective scattering index; OV: OQAS value.
