What is pachymetry when getting an eye exam?

ANSWER

This test uses ultrasound to measure the thickness of your cornea. Thin corneas can lead to false low-pressure readings. Thick corneas can lead to false high-pressure readings. You may get this test just once to create a baseline for comparison with future readings. It can be used for people who need corneal surgery.
