Hair washing is generally not recommended immediately after hemi-femtosecond surgery, but can be done about 1 week after the procedure. When patients take hemi-femtosecond surgery, it will cause some trauma to the eye. If washing hair immediately after surgery, it may cause water to splash into the eye, which is easy to cause infection. Therefore, it is recommended that patients wash their hair about one week after surgery, and when washing their hair, they should avoid randomly rubbing their eyes. After taking half femtosecond surgery, patients should pay attention to reasonable eye use and avoid using electronic products for a long time or staying up all night, in order to prevent affecting the postoperative recovery. Eat a light diet, with more protein and vitamins, and avoid spicy and stimulating foods. After the half-femtosecond surgery, if pain and other discomforts occur, it is recommended to consult a doctor in time to avoid delaying the condition and leading to adverse consequences.
