To determine intraocular pressure with a tonometer in which a measurement prism presses against the human eye with a given force and a corresponding relationship is established between the force and the area aplanated thereby, it is proposed that a plurality of measured values of force and aplanated area, each being associated with the other, be determined per unit of time during the course of a continuous increase in pressure by means of the power-driven, spring-pretensioned motion of the measurement prism and processed in the form of a curve in such a manner that the intraocular pressure can be determined differentially from the plurality of measured values.
