Armand Imbert (1850-1922) and Adolf Fick (1829-1901) both demonstrated, independently of each other, that in ocular tonometry the tension of the wall can be neutralized when the application of the tonometer produces a flat surface instead of a convex one, and the reading of the tonometer (P) then equals (T) the IOP," whence all forces cancel each other. This principle was used by Hans Goldmann (1899–1991) who referred to it as the Imbert-Fick "l… Witrynaforce using the Imbert-Fick principle.
