The control group consisted of 62 eyes in 31 unaffected subjects (mean age 26.26 \u00b1 3.64 years; 15 males and 16 females). The bIOP was determined using a Scheimpflug-based tonometer (Corvis Scheimpflug Technology [Corvis ST\u00ae]) after measuring the IOP with a conventional non-contact tonometer (NIOP). The agreement between NIOP and bIOP values was examined using the Bland-Altman plot. The difference between NIOP and bIOP (bIOP correction amount) was compared between keratoconus and FFK eyes. <b><i>Results:<\/i><\/b> In the control group, there were no significant differences between right and left eyes in both NIOP and bIOP values (<i>p<\/i> = 0.975 and <i>p<\/i> = 0.224, respectively). In the KC\/FFK group, NIOP values were significantly lower in the keratoconus eyes (9.93 \u00b1 1.96 mm Hg) than in the FFK eyes (12.23 \u00b1 3.03 mm Hg; <i>p<\/i> = 0.0003). There was no significant difference in bIOP values between the right and left eyes of the KC\/FFK group (<i>p<\/i> = 0.168). The bIOP correction amount was significantly increased in keratoconus eyes (3.58 \u00b1 2.12 mm Hg) compared to in FFK eyes (1.80 \u00b1 3.32 mm Hg; <i>p<\/i> = 0.011). <b><i>Conclusions:<\/i><\/b> For eyes with keratoconus and FFK, the bIOP method is effective to adjust IOP measurements based on corneal biomechanical properties.
