Abstract: An intraocular pressure detecting device includes the following elements. A force-applying element is adapted to apply a force to a target surface on a cornea of an eyeball in a direction, so that the target surface is deformed. A force-sensing element, coupled to the force-applying element, is adapted to sense the force applied by the force-applying element in the direction. A displacement-sensing element, coupled to the force-applying element, is adapted to sense a displacement of the force-applying element in the direction. A processing element is electrically connected to the force-sensing element and the displacement-sensing element to obtain a relationship curve between applied force and displacement. In particular, the processing element analyzes the relationship curve to obtain a characteristic critical point, and obtains an intraocular pressure value of the eyeball according to the applied force corresponding to the characteristic critical point.
