1. A system for measuring intraocular pressure (IOP) of a subject'"'"'s eye, comprising:
- a plurality of force sensors, said force sensors being adapted to contact a surface of the subject'"'"'s eye via moveable probes;
an advancing device for advancing said force sensors towards the subject'"'"'s eye in a controlled fashion;
a measuring device for measuring forces being exerted on said force sensors when said force sensors are in contact with the subject'"'"'s eye surface; and
a processor adapted to receive said measured forces and programmed to determine intraocular pressure (IOP) of the subject'"'"'s eye as a function of said measured forces, wherein said IOP of the subject'"'"'s eye is determined by finding intercepts of force curves with either vertical or horizontal axes, where a distance of said intercepts is proportional to intraocular pressure and an offset between the two force probes via the following relationship

Abstract
A system for measuring intraocular pressure (IOP) of an eye, comprising a plurality of force sensors that are adapted to contact a surface of an eye, measuring the forces exerted on the force sensors when in contact with the eye surface, and processing the measured forces to determine the 10P of the eye as a function of the measured forces.
