👉 In mathematics, keratometry is a method used to measure the curvature of an object's surface by measuring the angle between two perpendicular lines that pass through its center. Keratometry can be useful in various fields such as optics, radiology, and engineering. The process involves applying a series of measurements to the object's surface, which are then compared to known values in order to determine the curvature. The resulting angles are used to calculate the curvature of the object. Keratometry is an
