There are three surgical options for double eyelid surgery: threading, small incisions, and full incision. Double eyelid surgery not only turns single eyelids into natural, beautiful double eyelids, but can also be combined with eye surgery such as eye opening, muscle lifting, etc. to improve eye problems such as large and small eyes, swollen eyes, and drooping upper eyelids. There is no specified standard for the width of double eyelids, and there is no point in researching how many millimeters of double eyelids should be done. Not everyone is suitable for wide, large double eyelids, and the width needs to be determined according to the individual’s eyebrow-eyebrow spacing, the height and length of the eye slit, as well as the facial features and the overall image of the individual. After double eyelid surgery, you need to follow the doctor’s instructions for care, keep the skin around the eyes dry to avoid incision infection; you also need to prevent scar hyperplasia at the surgical site; pay attention to moisturize and soften the eyelid tissues to reduce the local tightness; you can have a normal diet after the surgery, but you need to eat fish and shrimp, spicy and stimulating foods and alcohol. Try to eat a light diet. Postoperative rest is conducive to recovery.
