    8 Device Description Mode of Operation of the Corvis® ST The Corvis® ST is a non-contact tonometer equipped with an optical Pachymetry function. The Corvis® ST measures intraocular pressure without contact with the eye by applying an air puff to the eye. During the air puff the eye gets illumi- nated by a 9 mm slit through the apex and a built-in high-speed camera re- cords the movement of the eye with more than 4000 images per second.
