Herber R, et al. - In this prospective, monocentric, case-control study at Department of Ophthalmology, Carl Gustav Carus University Hospital Dresden, Germany, investigators estimated 60 eyes of 60 healthy participants (Group I) and 60 eyes of 60 keratoconus patients (Group II) to assess the corneal biomechanical factors using the Ocular Response Analyzer dynamic bidirectional applanation device (ORA) and the Corvis ST dynamic Scheimpflug analyzer (CST). They observed the AUC for the corneal resistant factor and corneal hysteresis, 0.930 and 0.868 with a sensitivity of 87% and a specificity of 87%, and sensitivity of 80% and a specificity of 80%, respectively. They noticed good differentiation between healthy eyes and keratoconic eyes and between different severity grades of keratoconus were allowed via both devices.
