What does a pachymeter measure?

• A. Corneal thickness
• B. Corneal curvature
• C. Visual acuity
• D. Lens power

Answer: (A)

A pachymeter is a specialized instrument used primarily in ophthalmology to measure the thickness of the cornea. This measurement is crucial for various clinical assessments, including the evaluation of conditions like glaucoma, where corneal thickness can influence intraocular pressure readings and treatment decisions. By accurately determining corneal thickness, practitioners can help diagnose concerns about eye health, assess the risk of developing conditions like keratoconus, and monitor changes over time, particularly before and after surgeries such as LASIK. Other options refer to different measurements: corneal curvature pertains to the shape of the cornea and is typically measured with keratometers, visual acuity gauges the clarity of vision which is assessed through eye charts, and lens power relates to the refractive strength of lenses used in prescriptions. Each of these measurements plays a distinct role in ophthalmology but does not relate to the function of a pachymeter.
