What is the difference between femtosecond and semi-femtosecond surgery?

1. Operation method: Femtosecond surgery is to make a lens in the center of the patient's cornea with femtosecond laser, and then make a small incision at the edge of the cornea to take it out. Semi-femtosecond surgery is to uncover the patient's corneal flap, remove the corresponding diseased part of the patient, and then reset the corneal flap.
