What is the mean horizontal and vertical diameter of the human cornea, respectively?

The mean horizontal and vertical diameter of the human cornea are approximately 11.7mm and 10.6mm, respectively. This measurement is important in understanding corneal anatomy and is often utilized in various clinical settings, including contact lens fitting and surgical planning, such as for corneal transplants or refractive surgery.

The cornea is slightly wider horizontally than it is vertically, which is a characteristic feature of its elliptical shape. These dimensions can vary among individuals but the provided mean values are widely accepted standards in ophthalmology.

When examining the other options, it’s clear that they do not reflect the well-accepted mean diameters of the cornea. Understanding the typical measurements helps in diagnosing and managing ocular conditions effectively.
