Correlations of Corneal Spherical Aberration with Astigmatism and Axial Length in Cataract Patients

Table 3

Results of multiple linear regressions of the total corneal spherical aberrations and anterior corneal spherical aberrations in the astigmatism group, the control group, and the total enrolled patients.

Anterior corneal astigmatism was removed as a factor in all regressions. Beta = standardized coefficient; total SA = total corneal spherical aberration; anterior SA = anterior corneal spherical aberration; AL = axial length; CCT = central corneal thickness.
