What is tonometer?

A tonometer is a medical device used to measure the pressure inside the eye, which is crucial for diagnosing and managing glaucoma. By assessing intraocular pressure (IOP), tonometers help determine the health of the eye and guide treatment options. There are several types of tonometers, including non-contact (air puff) and applanation tonometers, each with its own method for measuring pressure. Regular eye exams using a tonometer can aid in early detection of eye conditions.
