Imbert fick principle

Witryna11 kwi 2014 · The Imbert-Fick principle states that the IOP can be estimated indirectly via measuring the force required to applanate or 'flatten' a known area of the cornea. (2) In its original form, the Imbert-Fick principle requires the applanated surface to be dry, perfectly elastic, infinitely thin and spherical, whereas the cornea meets none of these ... WitrynaThis principle was used by Hans Goldmann (1899–1991) who referred to it as the Imbert-Fick "law", thus giving his newly marketed tonometer (with the help of the …

IOP is typically considered to be the pressure inside the eye, but this is mostly incorrect. A better term would be transcorneal pressure difference. Applanation tonometry applies a force outside the eye that equals the force inside the eye (across the cornea) according to the Imbert-Fick principle.
