Application of femtosecond laser in ocular surgery.

The femtosecond laser is a type of laser that can produce pulses of light of extremely short duration. The application of femtosecond laser in surgery results in no thermal effect or shock wave, so that this laser is unlikely to cause tissue injuries outside the irradiation area of the laser beam. The femtosecond laser shows promising applications in refractive surgery and corneal transplantation due to its high precision and predictability. In this paper, we review the clinical application of the femtosecond laser in refractive surgery and corneal transplantation.
