The Gold Standard

Goldmann applanation tonometry is the most commonly used tonometer in clinical practice and remains the “gold standard” for tonometry worldwide. It was developed in the 1950s and is based on the Imbert-Fick law that states that the pressure in a sphere filled with fluid and surrounded by an infinitely thin and flexible membrane is measured by the counter-pressure, which just flattens the membrane to a plane.
