About Non-Contact Tonometers

Measuring eye pressure, or intraocular pressure (IOP), is an important part of a comprehensive eye exam. Tonometry determines this pressure by measuring the resistance of the cornea to indentation. Non-contact tonometry, also known as air-puff tonometry, measures IOP using a puff of air to applanate the cornea. The non-contact tonometer (NCT) records the force of the air column at the moment the cornea flattens and then calculates the fluid pressure in the eye. IOP is an important measurement in evaluating patients at risk of glaucoma as high eye pressure can damage the nerve fibers in the back of the eye. Unlike applanation tonometers, the NCT test is non-invasive so numbing drops to not need to be administered prior to testing making it particularly useful with children and sensitive adults.
