Ultrasound pachymeter

An ultrasound pachymeter is an ophthalmic instrument that uses ultrasonic waves to precisely measure the thickness of the cornea. Clinicians often use these devices to assess patients before refractive surgeries, such as LASIK, or to determine the appropriate power for intraocular lenses.

These devices typically operate using mains electricity and feature a specialized probe that makes direct contact with the eye surface. The system captures and displays measurement data, which may also include axial length and anterior chamber depth depending on the specific configuration.
