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 (=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.
本研究的目的是确定使用Corvis ST眼压计进行气吹式眼压（IOP）测量期间角膜振动的特征频率。研究了角膜振动频率与眼压的关系。两个选定的振动频率——最大振幅频率和频率分布区域的质心（其振幅高于50%，即CM50）——与未校正眼压和生物力学校正眼压（bIOP）存在显著相关性。CM50平均值与bIOP之间的相关性最高（=0.91）。根据所得结果，可以得出结论，角膜峰值的振动频率与测量的未校正眼压和生物力学校正眼压密切相关。
