The swelling of buried line disappears in about 3-5 days, but with incision, the swelling will last for 1 week, and if the downward extent is larger, the swelling will be felt for 1 month, but it varies from person to person; 2. Many people worry about turning into triple-white eyes after the operation, but because the downward to position is ligated from the outer part of the black eye, it will not result in the phenomenon of triple-white eyes. If the doctor has technical problems, it is inevitable that such phenomenon occurs; 3, the phenomenon of inverted eyelashes, but it can be improved by cutting the excess skin externally; 4, the lower eyelid recession or ectropion; 5, if there is left-right asymmetry, it can be repaired after the swelling has completely subsided for 6 months.
