Abstract:
1. A device for determining the intraocular pressure of an eye having a measurement arrangement comprising a measurement body, attached to a measurement arm, for applanation of the eye and a rotary knob attached to a shaft and rotatable about a rotational axis of the shaft, with the measurement arm attached radially to a pivot axis, the measurement arrangement further comprising a mechanical coupling between the rotary knob and the pivot axis, wherein the rotary knob is configured to be rotated around the rotational axis to generate an applanation force required for applanation of the eye, wherein the mechanical coupling comprises tension transmission means, with the tension transmission means attached to the pivot axis via a first lever arm, and attached to the rotational axis of the shaft via a second lever arm, whereby the tension transmission means is configured to be wound-up by a rotation of the rotary knob about the rotational axis.
