Pachymetry is a test that measures the thickness of the cornea. This is an important measurement to have before LASIK surgery to ensure that the cornea is thick enough for the procedure. Parathyroid hormone (PTH), activated partial thromboplastin time (aPTT), and Parvovirus B19 immunoglobulin G and M antibodies are not relevant tests for assessing corneal thickness.
