Topographic measurements and corneal pachymetry were performed using a Scheimpflug-based (Pentacam, Oculus, Germany) corneal topographer. Corneal hysteresis (CH) and corneal resistance factor (CRF) were measured with an Ocular Response Analyzer (ORA, Reichert Ophthalmic Instruments, Buffalo, NY). Endothelial cell count measurement was done using a specular microscope (CellChek, Konan, USA).Results: Right eye values of the subjects were taken for the study. The mean CH was 11.5 +/- 1.7 mmHg and the mean CRF was 11.2 +/- 1.4 mmHg. Mean intraocular pressure was 15.3 +/- 2.3 mmHg. The mean endothelial cell count was 2754 +/- 205 cells/mm(2). No correlation was found between biomechanical properties of cornea and endothelial cell count. There was a significant positive correlation between CH, CRF, and corneal thickness (p<0.001; r=0.79).Conclusions: The corneal biomechanical properties significantly correlated with corneal thickness. We found no correlation between CH and CRF with the endothelial cell density in normal subjects.eninfo:eu-repo/semantics/openAccessOcular response analyzerBiomechanical propertiesIntraocular-pressureKeratoconic eyesDiabetes-mellitusThicknessAgeParametersDystrophyCorneaCorneal stromaResearch & experimental medicineArticle0003548946000011460146321
