The applanation tonometer is a medical device used to measure intraocular pressure (IOP) in the eye. In ophthalmology, it is a frequently used instrument for the diagnosis and treatment of disorders like glaucoma.
The applanation tonometer works on the basis of measuring the force necessary to flatten a small portion of the cornea. The cornea, which is the transparent front surface of the eye, is essential for preserving a normal IOP because of its shape and thickness. The early detection and management of glaucoma, a disorder characterized by elevated intraocular pressure that, if untreated, can result in optic nerve damage and visual loss, depends on routine IOP monitoring with an applanation tonometer. Medical experts can choose the best course of treatment, which may involve medication, laser therapy, or surgery, by precisely evaluating IOP.
