The tip contains a hollow the same shape as the cornea with a Standardisation of tonometers book pressure sensor in its centre.

In contrast to applanation tonometry it is designed to avoid deforming the cornea during measurement and is therefore thought to be less influenced by corneal thickness and other biomechanical ICDCM: Tonometry refers to the indirect estimation of intraocular pressure by measuring resistance of the eye to indentation by an applied force.

At the most crude level, palpation of the eyeball with the fingertips and estimating turgidity is a form of tonometry. More accurately, and more safely, intraocular pressure is estimated with a variety of instruments that mechanically deform the globe and.

Tonometers measure the internal pressure of the eye and tonometry is one of the principal tests for glaucoma, but until relatively recently their use in the eye examination was far from routine. A patient's intraocular pressure (IOP) should normally be Any reading in the region of 21 or 22 signifies an increased likelihood that the patient will go on to develop glaucoma.

Tonometry is usually easy to go through, since the eye has been numbed by drops, so you feel nothing. During the actual measurement, the instrument can rub some cells from the cornea if it is not done gently. If the patient rubs his or her eye during the 20 minutes afterward, the cornea can also be scratched.
