Methods Keratometric reading with Topcon KR-8100 automatic keratometry and comeal topography with the TMS-4 on 53 ametropia' children, 106 eyes were compared. Difference in measurements of steep meridian power magnitude Ks, flat meridian power magnitude Kf, astigmatism magnitude Ks-Kf and location as well between the two methods were assessed using paired t test.Bland-Altmann method was used to evaluate the agreement of the two methods.
