Myopic full femtosecond has the advantages of minimal damage, fast procedure and quick return to eye use after the surgery, compared to its disadvantages such as limitation of corneal thickness requirement and irreversibility of the surgery. Myopia full femtosecond laser surgery is a popular way to correct myopia, which does not require a flap and causes only minimal damage to the corneal epithelium. After the surgery, patients can return to normal vision faster and with less pain, eye pain and other discomforts are not obvious. In addition, because femtosecond laser surgery is performed on the cornea, similar to making a negative lens in the corneal stroma, so it will have certain requirements for the thickness of the corneal stroma. If the patient has high myopia or the thickness of the corneal stroma is not enough, it is usually not suitable for femtosecond laser surgery. In addition, the procedure is irreversible. It is recommended that patients follow the doctor’s instructions, have regular checkups, and seek prompt medical attention when discomfort occurs.
