applanation tonometer

A device for measuring intraocular pressure (IOP) indirectly. The IOP depends on the amount of pressure that is required to flatten a section of the cornea.

applanation tonometer
measures the force required to flatten or applanate an area of cornea. Includes the MacKay-Marg, Halberg, Dräger and Goldmann tonometers.
indentation tonometer
measures the pressure required to indent the cornea; includes the Schiotz and pneumatonograph.
