誗 Femtosecond laser has the characteristic of high precision cutting, so it has great application potential in keratoplasty. It can replace the mechanical microkeratome used for penetrating keratoplasty, lamellar keratoplasty and endothelial keratoplasty according to the clinical need to produce different shapes of corneal graft and the graft bed. Femtosecond laser provides a new way for improving and optimizing the operation of various keratoplasty. In this paper, we reviewed the use of femtosecond Iaser in keratoplasty.
