Abstract:
1. A device for measuring intraocular pressure, comprising a housing; a movable bushing having a support, said movable bushing being placed within the housing and adapted to reciprocate therein within a limited range to apply a static load to the eyeball through the eyelid; a rod with a flat base, said rod being placed within the bushing to reciprocate relative, to the support and apply an impact force to deform the eyeball through the eyelid; and at least one measuring winding provided within the movable bushing, wherein the device is provided with a permanent magnet fitted on the rod, and the measuring winding is positioned relative to the permanent magnet so as to control the direction and speed of movement of the rod, said measuring winding being connected to a control, processing, and indication unit adapted to produce a voltage of opposite polarities across the measuring winding to retract the rod by an electromagnetic field to its initial position and thereafter to apply a pulse to cause the rod to move toward the support, signal from the measuring winding being converted to measure intraocular pressure and display the results, wherein the device is provided with a contactless indicator giving an indication of a specified static load being applied to the eyeball through the eyelid during measurement.
