<unk> s movement<unk> s (corneal fibroblasts) are specialized fibroblasts residing in the stroma. This corneal layer, representing about 85-90% of corneal thickness, is built up from highly regular collagenous lamellae and extracellular matrix components.<unk> s play the major role in keeping it transparent, healing its wounds, and synthesizing its components. In the unperturbed<unk> s stay dormant, coming into action after any kind of injury or inflammation. Some<unk> s underlying the site of injury, even a light one, undergo apoptosis immediately after the injury. Any glitch in the precisely orchestrated process of healing may cloud the cornea, while excessive<unk>  apoptosis may be a part of the pathological process in the degenerative corneal disorders such as keratoconus, and these considerations prompt the ongoing research into the function of these cells.
