We quantitatively evaluated the irregular astigmatism of 27 eyes of 19 patients with keratoconus by the sine curve approximation method. Both regular and irregular astigmatisms were significantly correlated with corrected visual acuity (R=0.48, p=0.011 and R=0.59, p=0.001, respectively). The multiple regression analysis revealed that the amount of irregular astigmatism mainly affects corrected visual acuity (p=0.027). The influence of regular astigmatism was not significant (p=0.281).
