Angle-W, angle corresponding to the corneal incision (incision width); CCI, clear corneal incision; D, diopter; Dis-En, the distance from incision entry to central cornea; Dis-Ex, the distance from incision exit to central cornea; IL, the straight distance from incision entry to exit (incision length); SIA, surgically induced astigmatism. ^*Significant (p < 0.0250) after correction for multiple comparisons (n = 6) based on false discovery rate (FDR); ^†significant (p < 0.0250) after correction for multiple comparisons (n = 8) based on FDR.
