Fig. 1: The anatomy of the eye and cornea.

The eye is an important visual organ that contains the cornea, lens, vitreous, retina, optic nerve, and other significant structures. The cornea is a transparent tissue at the front of the eye, which is composed of five distinct layers from anterior to posterior: CE, Bowman’s layer, corneal stroma, Descemet’s membrane, and the endothelium. Each layer of the cornea is crucial to its function since it not only acts as the first mechanical and immune barrier to the eye but also transmits and converges external light to the retina to produce vision.
