What does pachymetry measure?

Pachymetry specifically measures corneal thickness, providing crucial information about the health and characteristics of the cornea. This measurement is typically performed using an ultrasonic device or an optical method, and it plays a significant role in diagnosing and managing various ocular conditions, especially in the context of contact lens fitting, glaucoma assessment, and preoperative evaluations for refractive surgery.

Understanding corneal thickness can help in determining the appropriate type of contact lenses for a patient, as well as in monitoring the effects of certain conditions or treatments on the cornea over time. It is a vital parameter that can influence the decision-making process in both contact lens fitting and overall eye care.
