Purpose.
To investigate the relationship between corneal biomechanical parameters, anterior segment parameters, and geometric corneal parameters in a healthy Caucasian group.
Methods.
This retrospective study included the healthy eyes with best corrected visual acuity of at least 20/40 of 122 Caucasian subjects.
The anterior segment parameters and geometric corneal parameters such as corneal volume, central corneal thickness, horizontal and vertical corneal radii, anterior and posterior steep, and flat keratometric values were measured with a Scheimpflug camera.
The biomechanical properties were measured with Ocular Response Analyzer.
Results.
One hundred and twenty-two healthy Caucasian subjects (67 males, 55 females) with a mean age of 45.32 ± 20.23 were enrolled.
Both corneal hysteresis and corneal resistance factor were positively correlated with CCT ( r = 0.529 , p < 0.001 ; r = 0.638 , p < 0.001 ) and CV ( r = 0.635 , p < 0.001 ; r = 0.579 , p < 0.001 ) and negatively correlated with age ( r = - 0.373 , p < 0.001 ; r = - 0.249 , p < 0.001 ).
Both in age-gender and multivariate models, CH and CRF had statistically significant negative association with the posterior steep K value.
Conclusions.
CH and CRF are negatively correlated with posterior steep and average posterior K values.
