First of all, do a good job of shampooing and bathing, especially washing your face before operation, because it is inconvenient to clean after operation, so your hair must be washed; Also, when cutting double eyelids, don't wear dresses and other clothes, try to wear T-shirt shorts or trousers, mainly for the convenience of rest after surgery;

Secondly, be careful not to eat big fish and meat on the day of operation, and try to eat lightly. If you want to have an operation, you need a blood test and urine test before the operation, keep a normal diet, and don't drink too much coffee and carbonated drinks. Try to find friends to go with you, which is more convenient in terms of taking a car; There is also the need to know what drugs you are allergic to. If you don't know, you should seriously cooperate with the nurses to do relevant skin tests and physical examinations.
