A pachymeter is a medical device that utilizes ultrasound technology to measure the thickness of the eye’s cornea. It is used to perform corneal pachymetry prior to LASIK surgery, for Keratoconus screening, and is useful in screening for patients suspected of developing glaucoma, as well as other corneal diseases. At Eye Care Center, we also utilize pachymetry for the management of an eye condition called Fuch's corneal dystrophy.
