ABSTRACT
The cornea constitutes the most anterior surface of the eye. Histologically, it comprises a stratified squamous epithelium facing the ocular tear film, a dense connective tissue stroma, and a simple cuboidal endothelium facing the anterior chamber. Although the morphology of the cornea is relatively simple, its three layers are highly specialized for the refraction and transmission of light, and for the prevention of intraocular infection.
