There are several methods to perform tonometry, each with varying levels of comfort and accuracy:
Applanation Tonometry: This involves flattening a small part of the cornea to measure IOP. It is considered the gold standard but may require sedation in young children. Non-Contact Tonometry: Also known as the "air-puff" test, this method uses a puff of air to measure IOP. It is less invasive and often more acceptable to children. Tono-Pen: A handheld device that provides a quick and relatively comfortable way to measure IOP, often used in younger or less cooperative patients.
