Abstract
The aim of this study was to determine characteristic frequencies of corneal vibrations occurring during air-puff intraocular pressure (IOP) measurement using the Corvis ST tonometer. Relations of frequency of the corneal vibrations with IOP were examined. Two selected vibration frequencies-frequency with maximum amplitude, and mass center of the frequency distribution area, for which the amplitude was higher than 50% (CM50)-present significant correlations with non-corrected IOP and biomechanical corrected IOP (bIOP). The highest correlation was found between the mean values of CM50 and bIOP (r=0.91). Based on the results obtained, it can be stated that the vibration frequencies of corneal peaks are closely related to the measured non-corrected and biomechanical corrected IOPs.
