what is the outer layer of the cornea
The cornea can be referred to as, âthe window to the eyeâ. It is in the front of the eye and covers the iris, pupil and anterior chamber. The human cornea is comprised of six different cell layers: Epithelium, Bowmanâs Layer, Stroma, Duaâs Layer, Descemetâs Membrane and Endothelium. The epithelium is the outermost layer of the cornea and accounts for about 10% of the cornea tissueâs thickness. The epithelial layer has two main functions: to obstruct the passage of foreign materials and to absorb oxygen and nutrients from the eyeâs tears to provide a smooth surface layer.
