Excimer laser surgery and full femtosecond surgery mainly differ in surgical methods, laser modes, recovery time and price. 1. Surgical mode: Excimer laser needs to make a corneal flap, and at the same time cut the stroma layer under the flap, while full femtosecond does the cutting in the stroma layer of the cornea, and after cutting, it exists in the form of lens, which is taken out through a 2mm incision on the cornea. 2. Laser mode: Excimer laser uses an excimer laser mode, while full femtosecond surgery uses a femtosecond laser. 3. Recovery time: Excimer laser surgery has a relatively large incision and usually requires six months to one year of recovery time, while full femtosecond laser has a small incision and usually allows you to use your eyes in 24 hours. 4. Price: The price of molecular laser is usually around 10,000 yuan, while full femtosecond is more expensive than molecular laser, usually around 20,000 yuan. Myopia surgery is highly specialized, so it is recommended to go to regular medical institutions for examination and surgery.
