Explanation:
Corneal thickness is what a pachymeter measures. It provides the central corneal thickness, typically in micrometers, using ultrasound or optical methods. This measurement matters because corneal thickness influences how we interpret intraocular pressure readings from standard tonometry—a thicker cornea can make IOP appear higher, while a thinner cornea can make it seem lower. Pachymetry itself does not measure pressure; it gives thickness data to refine IOP assessment and aid decisions in refractive surgery planning. It is not used to measure axial length or tear film osmolarity, which are obtained with other instruments.
