Several laser refractive surgical procedures have been used to reshape the cornea to correct refractive error. During the procedures of making corneal flap and ablation, it would inevitably make some damages to corneal nerves. The procedures of laser surgery, the depth of ablation and the thickness of corneal flap play important roles in the damage of corneal nerves. In this review we study the mechanism of corneal nerve damage caused by several main laser eye surgery and the factors which may accelerate the regeneration of corneal nerve, in order to improve the surgical quality.
