Considerations when renting or leasing a tonometer
Tonometers are automatic devices that help to measure the pressure inside the eye. Features of tonometers include eye drops to numb the eye, as well as detection systems that can help read for glaucoma and other important eye diagnoses. Most tonometers use either electronic indentation processes or non-contact processes. With electronic indentation, the tonometer features a tool that the doctor places onto the cornea, which automatically relays pressure information to the machine to determine whether or not the eyes have glaucoma.
Noncontact tonometry is commonly known as the air-puff method, and it uses a puff of air to flatten the cornea temporarily while a reading is done. This way of measuring pressure is quick and mostly painless to the patient, and easy for the ophthalmologist to read. It targets the type of pressure in the eye and uses an advanced system to take readings that will indicate the presence of glaucoma.
