To measure the curvature of the cornea

To measure intraocular pressure to screen for glaucoma

The primary purpose of a tonometer in eye care is to measure intraocular pressure, which is crucial in screening for glaucoma. Elevated intraocular pressure is one of the key risk factors for glaucoma, a group of eye diseases that can lead to vision loss if not detected and treated early. Tonometers can provide valuable data that assist eye care professionals in diagnosing potential glaucoma and tracking the efficacy of treatments over time.

While measuring the curvature of the cornea, examining the retina, and assessing the performance of vision therapy are important in various aspects of eye care, they do not pertain to the specific function of a tonometer. Thus, the tonometer's role in monitoring intraocular pressure is essential for the early detection and management of glaucoma.
