You should not rub your eyes for 3 months after the semi-femtosecond laser surgery. Semi-femtosecond laser surgery is currently a common means of correcting myopia, through the use of femtosecond laser to create a corneal flap, and then under the flap using an excimer laser to cut the corneal stroma, it can play a role in repairing the patient’s refractive defects of the cornea, to achieve the purpose of correcting myopia, and then you need to reset the flap, to restore the normal anatomical structure of the cornea. It will take about three months to fully recover and stabilize the cornea after the surgery. During this period, rubbing the eyes will easily cause the corneal flap to shift, thus affecting the recovery effect, so the patients are not allowed to rub their eyes. It is also important to avoid eye trauma and other irritating factors.
