TONOMETER

A tonometer is a medical device used to measure the pressure inside your eye, known as intraocular pressure (IOP). This measurement is crucial for detecting and managing glaucoma, a condition that can lead to vision loss if left untreated1.

There are several types of tonometers, including:

• Applanation tonometry: Measures the force required to flatten a small area of the cornea.
• Non-contact tonometry: Uses a puff of air to measure eye pressure without touching the eye.
• Tono-Pen: A handheld device that gently touches the eye to measure pressure.
• Dynamic contour tonometry: Uses a sensor-tipped extension that touches the eye without making an indentation.
