corneal

adjective

Example sentencesExamples

- In the pipeline are many other applications, including vascular, pancreatic, and corneal repair.
- It is important to identify and remove conjunctival and corneal foreign bodies.

Origin

Late Middle English: from medieval Latin cornea tela 'horny tissue', from Latin cornu 'horn'.

horn from Old English:
The word horn is related to corn ‘a painful area of thickened skin’, and cornea (Late Middle English) through its ancestor Latin cornu ‘horn’.
