This corneal layer, representing about 85-90% of corneal thickness, is built up from highly regular collagenous lamellae and extracellular matrix components. Keratocytes play the major role in keeping it transparent, healing its wounds, and synthesizing its components. This cell type secretes collagen I, V, VI, and keratan sulfate. corneal keratocyte corneal fibroblast substantia propria of cornea
