They are commonly written as \u201cK\u201d values, often with a flat and a steep meridian. Clinicians use them to estimate corneal focusing power and corneal astigmatism. They are routinely collected in optometry and ophthalmology clinics, especially before contact lens fitting and cataract surgery planning."}
