Modelling the dynamic contactless tonometer test. Numerical simulation of the contactless tonometer test. a Air jet pressure versus apex displacement curve. b Cornea NT profile at the maximum value of the air jet. Two thin lines visualize the anterior and posterior surfaces of the cornea at the physiological IOP. c Distribution of the NT stress component along the NT meridian section at the maximum deflection of the cornea (correct physics). d Distribution of the NT stress component along the NT meridian section at the maximum deflection of the cornea in the absence of the fluid (wrong physics)
