## Definition

relating to the clear, outer layer of the eye. This layer is called the cornea and helps you see clearly.

For teachers: relating to or affecting the cornea, the transparent outermost layer of the eye. Typically used in medical or biological contexts to describe structures or conditions affecting vision.

## Examples

- The doctor checked for any corneal damage after the accident.
- Advances in laser technology have made corneal surgery much more precise and less invasive for patients.
- The patient was diagnosed with a rare corneal dystrophy that causes the normally transparent tissue to become cloudy over time, eventually impairing visual acuity.
