What does the apex of the cornea refer to?

• A. The lowest part of the cornea
• B. The center section of the cornea
• C. The highest/steepest part of the cornea
• D. The outer edge of the cornea

Answer: (C)

The apex of the cornea refers to the highest or steepest part of the cornea. This anatomical feature is crucial in understanding the cornea's shape and curvature, as it plays a significant role in focusing light onto the retina. The curvature at the apex affects how light is refracted when it enters the eye, thus influencing visual clarity and focusing power. In the context of the cornea, the apex is typically located slightly off-center toward the nasal side, contributing to the cornea's overall shape and its ability to refract light effectively. Understanding the location of the apex is essential for various clinical applications, such as fitting contact lenses and assessing conditions like astigmatism, where the curvature deviates from the norm.
