It is not forever that you can’t rub your eyes after semi-femtosecond surgery; you can’t rub your eyes for up to a month after the surgery, but it is not recommended on a daily basis either. Semi-femtosecond surgery involves the use of a femtosecond laser to create a corneal flap, followed by an excimer laser to cut the corneal tissue and adjust the curvature of the cornea to achieve correction of myopia. The advantage of hemi-femtosecond is that it allows for precise correction according to the degree of myopia. Because of the need to make a corneal flap, semi-femtosecond surgery is not allowed to rub the eyes within one month after the surgery. At this time, the position and nature of the flap are not yet completely fixed, otherwise it is very easy to cause the flap to shift, and the shift of the cornea will lead to poorer surgical results or even surgical failure. It is not recommended to rub the eyes within one month after the hemifemtosecond surgery, and it is recommended to rub the eyes under the guidance of the doctor according to the specific conditions of the surgery. However, the fact is that it is unhygienic to rub your eyes with your hands, so try not to rub your eyes with your hands in your daily life.
