Corneal epithelium
Corneal corpuscles appearing fusiform in section
  • Lamellae, the fibers of which are cut longitudinally
  • Transition to the sclera, with more distinct fibrillation, and surmounted by a thicker epithelium
  • Small blood vessels cut across near the margin of the cornea

    Anatomical terminology]

    The corneal epithelium (epithelium corneae anterior layer) is made up of epithelial tissue and covers the front of the cornea. It acts as a barrier to protect the cornea, resisting the free flow of fluids from the tears, and prevents bacteria from entering the epithelium and corneal stroma.

    Anatomy

    The corneal epithelium consists of several layers of cells. The cells of the deepest layer are

    squamous cells, with flattened nuclei. The layers of the epithelium are constantly undergoing mitosis
    . Basal and wing cells migrate to the anterior of the cornea, while squamous cells age and slough off into the tear film.

    Central thickness of corneal epithelial layer is approximately 50 to 52 μm.[2]

    Cornea cell LASIK complication

    Epithelial ingrowth is a LASIK complication in which cells from the cornea surface layer (epithelial cells) begin to grow underneath the corneal flap. This complication is not present in PRK or other non-flap vision correction procedures.
