The four factors, applanating force, applanated area, intraocular pressure and displaced intraocular volume were measured simultaneously and independently in enucleated human eyes. The experiments were carried out at constant intraocular pressure. The relationship between applanating force, intraocular pressure and applanated area was in good agreement with a straight line, but the applanated area was smaller than expected on the basis of the Imbert‐Fick law. The displaced intraocular volumes were larger than would be expected from the corneal applanation alone calculated as spherical segments and indicated additional deformation of the eyeball. The displaced intraocular volume can also be estimated directly from applanating force and intraocular pressure without including applanated areas.
