Patent ID: 10478064

Abstract:
A device for determining an intraocular pressure of an eye is disclosed. The device comprises; (a) a housing; (b) a plunger axially movable within the housing, a first end of the plunger having a tip for contacting the eye; (c) an indicator arm operatively connected to a second end of the plunger; (d) a measurement gauge for indicating the intraocular pressure of the eye; and (e) a resilient biasing member for biasing the plunger towards an extended position in which the plunger tip protrudes beyond the housing and the indicator arm is biased towards a first position on the measurement gauge. Applying pressure to the eye via the plunger tip causes the intraocular pressure of the eye to exert an opposing force on the plunger tip causing the plunger to retract into the housing to cause a reciprocal movement of the indicator arm towards a second position thereby indicating the intraocular pressure of the eye on the measurement gauge.
