Streszczenie:
Two commercially used noncontact tonometers: the Ocular Response Analyzer (ORA) and the Corvis ST (CST) are presented. The devices measures biomechanical properties of the cornea that are essential for better understanding of the optical and the geometrical properties of the cornea. Characteristic parameters for both ORA and Corvis ST are described. One of the main ORA parameter is corneal hysteresis (CH) which is supposed to represent the viscoelastic properties of the cornea. The main advantage of Corvis ST is a high-speed Scheimpflug camera capable of taking two-dimensional images of a cross-section of the cornea during its deformation, which can possibly give additional information about the biomechanical status of the cornea.
