A tonometer is a device used to measure the pressure inside the eye, also known as intraocular pressure (IOP). Tonometers are used to diagnose and monitor glaucoma, a condition that can damage the optic nerve and lead to vision loss. Tonometers come in two main types: applanation and non-contact. Applanation tonometers are the most commonly used type, and involve the patient's eye being gently flattened with a small, plastic device. Non-contact tonometers measure IOP without touching the eye, and can be used in children and people who are unable to cooperate with applanation tonometry.
The Tono-Pen is a type of non-contact tonometer that is small, portable, and easy to use. It measures IOP by sending an electronic pulse through the cornea and measuring the amount of time it takes for the pulse to return. The Tono-Pen is often used in emergency situations and in remote locations, as it does not require any special equipment or training to use.
The price range for tonometers and Tono-Pens varies depending on the type, brand, and features. Basic applanation tonometers can cost around $400, while more advanced models can cost up to $1000. Non-contact tonometers and Tono-Pens can range from $500 to $2000. Major manufacturers of tonometers and Tono-Pens include Reichert, Haag-Streit, and Topcon.
