The testing, which is painless, is done to determine the strength of the IOL needed. The ophthalmologist measures the length of the patient's eyeball with ultrasound and the curvature of the cornea with a device called a keratometer.

How do you interprete a keratometry reading?

A keratometry reading measures the curvature of the cornea. It provides information about the cornea's shape and can be used to calculate the power of prescription lenses needed for conditions like astigmatism or to evaluate suitability for contact lenses or refractive surgery. A higher reading indicates a steeper cornea, while a lower reading indicates a flatter cornea.
