Evaluation of biophysical alterations in the epithelial and endothelial layer of patients with Bullous Keratopathy.

The cornea is a fundamental ocular tissue for the sense of sight. Thanks to it, the refraction of two-thirds of light manages to participate in the visual process and protect against mechanical damage. Because it is transparent, avascular, and innervated, the cornea comprises five main layers: Epithelium, Bowman's layer, stroma, Descemet's membrane, and endothelium.

Layer-by-Layer Investigation of Ultrastructures and Biomechanics of Human Cornea.

The cornea is an avascular, innervated, and transparent tissue composed of five layers: the epithelium, Bowman's layer, stroma, Descemet's membrane, and endothelium. It is located in the outermost fraction of the eyeball and is responsible for the refraction of two-thirds of light and protection from external mechanical damage. Although several studies have been done on the cornea on the macroscopic scale, there is a lack of studies on the micro-nanoscopic scale, especially an analysis evaluating the cornea layer by layer.
