The whole femtosecond process of eye laser surgery

The procedure of femtosecond laser surgery includes anesthesia, corneal flap making, laser correction, irrigation and inspection.

1. Anesthesia

femtosecond laser surgery generally uses surface anesthesia, that is, anesthetic eye drops are dripped into the eye, so that the patient does not feel pain during the surgery.

2. Making corneal flap The

doctor uses femtosecond laser equipment to make a thin corneal flap on the cornea. This process usually takes only a few seconds, which is one of the key steps of femtosecond laser surgery.

3. Laser correction

After making corneal flap, the doctor will start the femtosecond laser equipment to accurately correct the cornea. The laser will cut the corresponding shape on the cornea according to the patient's vision problems, thus changing the refractive power of the cornea.

4. Irrigation and inspection

After the surgery is completed, the doctor will rinse the eye and check the position and correction effect of the corneal flap. If everything is normal, the doctor will reattach the corneal flap to the cornea.
