  1. P1 = P-value of the difference between visual quality parameters before surgery and one week after surgery; P2 = P-value of the difference between visual quality parameters before surgery and one month after surgery; P3 = P-value of the difference between visual quality parameters before surgery and three months after surgery
  2. MTF modulation transfer function, OSI objective scattering index, OV OQAS value
  3. *P < 0.05 = significant difference
