Abstract
A tonometer with an improved objective unit containing a fluid discharge tube having a portion thereof extending into a plenum chamber enhances the consistency of repeated regulated air discharges. The consistency is further enhanced by texturizing the inner wall of the discharge tube. Since the discharge tube extends into the plenum chamber, the objective unit can have substantial interchangeability with other tonometers.
