Comparison of corneal irregular astigmatism by the type of corneal regular astigmatism
Scientific Reports, 2021 We investigated the relation between corneal regular and irregular astigmatism in normal human eyes. In 951 eyes of 951 patients, corneal irregular astigmatism, such as asymmetry and higher-order irregularity components, was calculated using the Fourier ...
