Average LMTH for Keratograph was 235.4657.61 m , whereas the mean LTMH measured by OCT was 245.8467.18 m. Intraobserver repeatability and interobserver and intersession reproducibility were moderate with Keratograph ( CoV 0.16 % , 0.19 % , 0.17 % and ICC 0.83 , 0.76 , 0.83 , respectively ) and high for the Spectralis OCT ( CoV 0.13 % , 0.12 % , 0.11 % and ICC 0.9 , 0.92 , 0.92 , respectively ) .
