Correlation between the NIBUT and (A) NIKBUT-first and (B) -average without SCL. Positive correlations are seen between the NIBUT and NIKBUT-first without SCL (r=0.445, P=0.0488, Pearson’s correlation coefficients). Bland-Altman plot represented the agreement between the NIBUT and (C) NIKBUT-first and (D) NIKBUT-average without SCL. The solid line shows the upper and lower limits of agreement between the two parameters. The dotted line represents the mean differences between the two parameters.

Abbreviations: NIBUT, noninvasive interferometry break up time; NIKBUT, noninvasive Keratograph break up time.
