What is keratometry used for?

Keratometry is a diagnostic procedure specifically used to measure the curvature of the cornea, which is the transparent front part of the eye. This measurement is crucial in various aspects of eye care. By quantifying the curvature, keratometry aids in assessing the cornea's shape and determining refractive errors, which can help in the fitting of contact lenses and planning for refractive surgery.

In addition, understanding the curvature of the cornea can provide insights into certain conditions such as astigmatism, where the cornea is irregularly shaped. Therefore, keratometry is a vital tool for optometrists and other eye care professionals in delivering precise eye care and correction options tailored to individual patients' needs. Other options presented focus on different aspects of eye health and vision assessment that do not relate to the curvature measurement of the cornea.
