Keratometry specifically assesses the curvature of the cornea, which is a vital measurement in optometry. This procedure involves using a keratometer to measure the radius of curvature of the anterior surface of the cornea. Understanding the curvature is essential for various reasons, such as determining the appropriate fitting parameters for contact lenses, diagnosing certain eye conditions, and planning for refractive surgeries like LASIK. By measuring the curvature, eye care professionals can gain insights into the cornea's shape, which plays a crucial role in overall vision quality, thus making this the correct answer.
