Abstract
The aim of the study presented here, is to understand and characterize the air puff generated by a non‐contact tonometer (NCT). Therefore, we propose a method to experimental calibrate a computational fluid dynamic (CFD) model of an eye examined with a Corvis ST. The time dependence of the nozzle pressure was found to be equal to the pressure measured by a device intern sensor. However, the maximum pressure identified at the nozzle inlet reaches approximately 25 kPa.
