From: Corneal functional optical zone under monocular and binocular assessment
Correlation between the estimated binocular oblique astigmatism to the estimated monocular oblique astigmatism and the Intercorneal difference in terms of oblique astigmatism. The estimated binocular oblique astigmatism showed a very strong positive correlation (even/direct symmetry) to the intercorneal differences in terms of oblique astigmatism however showing a poor correlation to the estimated monocular values
