Abstract: Corneal visualization scheimp fl ug technology (Corvis ST) is a new device that combines Scheimp fl ug high-speed camera with air-jet indentation system to measure the corneal biomechanics. Corvis ST can monitor the whole process of real-time dynamic corneal deformation, and record the deformation parameters to analyze the corneal biomechanical properties. Measurement principle and operation method, the reliability of parameters and clinical applications of Corvis ST are reviewed in this study.
