Non-contact tonometry (or air-puff tonometry) is different from pneumatonometry and was invented by Bernard Grolman of Reichert, Inc (formerly American Optical). It uses a rapid air pulse to applanate (flatten) the cornea. Corneal applanation is detected via an electro-optical system.

The PAT signal is a form of pulse wave amplitude measured by incorporating both a unified pressure field and a specific isosbestic wavelength.Applying a uniform pressure field around the measured surface releases arterial wall motion restriction, magnifies the dynamic range of the recorded signal, and prevents the distention of the veins distal to the site of pressure application.
Pressure is applied to the cornea until the inner edges of two semicircular fluorescein mires come into contact, forming a continuous circle. The corresponding reading on the tonometer scale represents the IOP of the measured eye. Intraocular pressure (IOP) can be measured by tonometry devices. The eye can be thought of as an enclosed ...
