A pachymeter is a medical device used to measure the thickness of the eye's cornea. It is used to perform corneal pachymetry prior to refractive surgery, for Keratoconus screening, Cataract, LRI surgery and is useful in screening for patients suspected of developing glaucoma among other uses.

What is Pachymetry and why is it being used in eye examinations?

Pachymetry is a simple, painless test to measure the thickness of your cornea -- the clear window at the front of the eye. A probe called a pachymeter is gently placed on the front of the eye (the cornea) to measure its thickness.

Why Pachymetry is important in glaucoma?

Pachymetry allows us to estimate the intraocular pressure with higher precision. Therefore it should be clinically used.
