How many degrees of myopia can be femtoseconds

Femtosecond laser surgery refers to femtosecond laser surgery. Generally, patients with myopia of 100-1200 degrees can do femtosecond laser surgery, which is related to the type of laser.

Femtosecond laser surgery includes full femtosecond laser surgery and half femtosecond laser surgery. Full femtosecond laser surgery is a method that uses femtosecond laser to scan the corneal layer to form a lens, and then removes the lens through a microincision to achieve the purpose of correcting vision. It is mainly suitable for myopia patients with myopia of 100-1000 degrees. Semi-femtosecond laser is a method of using femtosecond laser to make corneal flap, and then cutting corneal tissue by excimer laser to finally correct vision. This method is mainly suitable for myopic patients with 100-1200 degrees.
