Pachymeter

A Pachymeter is an instrument that measures the thickness of a cornea. A small probe is placed on the center of the cornea and an ultrasound measurement is taken. With the corneal thickness measurement and the NCT (non-contact tonometer) measurement, the doctors can calculate the intraocular pressure more precisely. The pachymeter would be used in cases where patients have unexplained elevated pressure readings from the NCT (puff of air machine). Another use for the pachymeter is to determine whether a person is a good candidate for refractivce surgery... if your cornea is too thin, some surgeries are not recommended. Our technicians are fully trained to take accurate pachymetry measurements.
