What is a Handheld Ref/Keratometer?
A Handheld Ref/Keratometer is a dual-function instrument that combines two critical eye diagnostic tools — a refractometer and a keratometer — into one compact device. It measures refractive power (for detecting nearsightedness, farsightedness, and astigmatism) and corneal curvature (used to fit contact lenses or detect corneal abnormalities).
Unlike traditional tabletop units, the Nidek HandyRef-K offers portability and flexibility, allowing eye specialists to perform tests efficiently in hospitals, clinics, or even remote areas where conventional equipment might be unavailable.
