Corneal transplantation, also known as corneal grafting or keratoplasty, involves replacing a damaged or diseased cornea with a donor cornea. The cornea is the transparent, anterior part of the eye that plays a crucial role in focusing light onto the retina. Histologically, the cornea consists of five main layers: the epithelium, Bowman's layer, stroma, Descemet's membrane, and the endothelium.
