A method for measuring intraocular pressure includes a probe supported and located in a suitable case, means for giving the probe a specific velocity, and means for processing and displaying the measurement data and controlling operations. According to the method, the probe is given a specific, relatively large initial acceleration, by feeding a voltage/current pulse to the means, particularly a coil, the velocity of the probe is detected using the second means, particularly a coil, on the basis of the data obtained from which, the magnitude of the voltage/current pulse is reduced, in order to reduce and stabilize the acceleration of the probe, the voltage/current pulse is maintained up until the moment of impact of the probe with the eye, or even after the moment of impact, and the impact of the probe is detected with the aid of the coil, in order to calculate and obtain the measurement result, and if desired, the probe is retracted to its departure position within the apparatus, by using the voltage fed to the coil.
