Abstract
An experimental study has been made on the performance of select applanating tonometer sensors applied to artificially-pressurized enucleated rabbit eyes. Open stopcock data have been found to be in good agreement with an analytical model developed in an earlier study in which pressurized rubber diaphragms were used as eye simulators. This study therefore substantiates the validity of the simple membrane model for this type of applanating tonometer. It further provides guidelines for sensor construction and calibration. Some closed stopcock measurements were made to show that the probe pressure accurately monitors the intraocular pressure after the break point, i.e., where the probe fully contacts the cornea.
