From: Gender-differences in age-related changes of corneal astigmatism in Korean cataract patients
The average J0 values for anterior and total corneal astigmatism, according to age in male and female patients. For men, β = − 0.018 in both anterior and total corneal astigmatism, and p < 0.001 for both types. For women, β = − 0.016 in both anterior and total corneal astigmatism, and p < 0.001 for both types (β is the regression coefficient, based on linear regression analysis; J0 is the Jackson cross-cylinder, axes at 180 degrees and 90 degrees). ACA, anterior corneal astigmatism; D, diopter; TCA, total corneal astigmatism
