Purpose Study about the biomechanical characteristics of the cornea. Methods We studied 122 eyes of 61 patients (33 women and 28 men) selected prospectively and consecutively. Range of age was between 18 and 60 years. The following determinations were carried out: Corneal topography with KERATRON (Optikon), measurement with ORA (Reichert) and ultrasonic pachymetry. The correlation between CCT ‐ CRF was calculated by SPSS 12.0 (Statistical Package for the Social Sciences, Chicago, IL) using the correlation of Pearson for quantitative and independent variables. Results We found after statistical analysis of data, a statistically significant correlation between the corneal resistance factor determined by the ORA, and central corneal thickness measured by ultrasonic pachymetry. The results are similar analysing both eyes as well as left and right eyes separately. Conclusion The importance of corneal biomechanical parameters like CH and CRF, values determined by the ORA, is not well defined yet; however the influence of these factors not only on intraocular pressure but also on corneal pathologies should be considered.
