Pre- and postoperative changes in compensation for spherical aberration, coma, and trefoil. (a) The proportions of eyes that exhibited a preoperative compensation effect for primary spherical aberration and horizontal trefoil are significantly higher (red) and lower (blue), respectively, under mesopic illumination than under photopic illumination; Chi-squared test. (b) The proportion of eyes that exhibited a postoperative compensation effect for spherical aberration, coma, and trefoil does not significantly differ between mesopic and photopic illumination; Chi-squared test. (Z40, primary spherical aberration; Z31 and Z3− 1, coma; Z33 and Z3− 3, trefoil)
