Which type of tonometer is designed to make contact with the cornea?

The Goldmann tonometer is specifically designed to make direct contact with the cornea during intraocular pressure measurement. This device utilizes a method known as applanation tonometry, wherein a small, curved measuring tip gently flattens a predetermined area of the cornea while measuring the force required to achieve that flattening. This technique provides a reliable assessment of intraocular pressure, which is crucial for diagnosing glaucoma and monitoring overall eye health.

The design and function of the Goldmann tonometer make it a widely accepted standard in clinical settings, particularly for its accuracy and precision in measuring intraocular pressure. The direct corneal contact, along with the careful calibration of the device, allows for accurate reflection of the pressure within the eye, which is essential for effective patient care and treatment planning.
