How to distinguish between full femtosecond and half femtosecond myopia surgery

The difference between full femtosecond and half femtosecond myopia surgery is that the damage size is different, the incision size is different, and the laser is different. The details are as follows:

1. The damage size is different. The

full femtosecond incision is smaller for the eye tissue, and the half femtosecond incision may cut off the corneal nerve, and the damage degree is larger.

2. The incision size is different. The

full femtosecond incision is smaller, which may be about 2 mm, while the half femtosecond incision is about 300 degrees.

3. The laser is different

. The femtosecond laser is used to make the corneal flap first, and then the excimer laser is used to cut the degree.
