Which term refers to the outer surface of the cornea comprised of 5-6 layers of cells which replace themselves continuously?

Explanation:
The outer surface of the cornea is the corneal epithelium, a stratified, non-keratinized sheet about 5–6 cell layers thick that continually renews itself. New cells arise from basal cells at the limbus, migrate toward the surface, and are shed from the outermost layer, keeping the surface smooth and transparent. This constant turnover also allows rapid repair after minor injuries. The other terms don’t describe this surface: an intraocular lens implant is a device inside the eye, an epithelial defect is a damaged area of the epithelial layer, and the fornix is a conjunctival recess, not the corneal surface.
