Postoperative care is very important, and the following points need to be done: 1, postoperative conjunctiva is fragile, and direct sunlight should be avoided. 2. After taking out stitches, apply local hot compress or use scar softening cream at the incision position. 3. Avoid using some wrinkle-removing beauty products containing heavy metals, especially mercury, after cutting double eyelid surgery. Don't touch the wound with water to avoid infection. 5. The postoperative diet is light and nutritious, and spicy and irritating foods, such as cigarettes, wine, peppers, soy sauce and ginger, should be avoided. 6. Pay attention to rest during the recovery period and avoid excessive use of eyes.
