Tonometry is commonly used to measure a patient’s intraocular pressure (IOP). Given the link between fluid pressure inside the eye and the onset of glaucoma, tonometers have become the principle test for glaucoma diagnosis.

Glaucoma examinations are, therefore, a vital part of ocular healthcare. They can help determine a patient’s risk of developing a range of eye diseases which can lead to eye pain, mid-dilated pupils, redness of the eye, nausea, damage to the optic nerve and eventually vision loss. A tonometer will identify four main types of glaucoma: primary open angle glaucoma, primary angle closure glaucoma, secondary glaucoma, developmental glaucoma (congenital glaucoma). These range from chronic to acute forms of glaucoma development. 

Our applanation tonometers are manufactured by Keeler. They are highly distinguished as the “true leaders” in the tonometry field. Their technological prowess provides optometrists with highly accurate and reliable IOP measurements.

Our range of standard and digital tonometers fall into two main categories; contact tonometers and non-contact tonometers (pneumotonometry).
