What tool is commonly used for assessing corneal curvature?

• A. Pachymeter
• B. Tonometry
• C. Keratometer
• D. Ophthalmoscope

Answer: (C)

The tool commonly used for assessing corneal curvature is the keratometer, also known as an ophthalmometer. This device measures the curvature of the anterior surface of the cornea, which is crucial for determining the shape and refractive power of the eye. The keratometer provides readings that are essential for several tasks, including fitting contact lenses, assessing corneal health, and preparing for surgical procedures such as LASIK.

Keratometry is particularly important in optometry as the curvature of the cornea significantly influences how light is refracted into the eye, directly affecting vision quality. By providing precise measurements of corneal curvature, the keratometer enables practitioners to make informed decisions about treatment options and corrective lenses.
