Pachymetry

At Evans and McMahon Eyecare Plus we use the Pachymate handheld pachymeter. This device allows for very accurate and speedy measurements. In fact, it is accurate to within 5 one thousandths of a millimetre.

Pachymetry is a specialised technique for measuring the thickness of the cornea (the clear layer at the front of the eye). This measurement is important as it can affect the eye pressure measurements taken when examining eyes for glaucoma. It is also very useful in situations of corneal disease, such as keratoconus where it can aid in analysis of disease progression
