The harm of double eyelid cutting is mainly caused by improper operation. Mild hematoma can subside by itself, and severe hematoma or progressive hematoma needs incision to stop bleeding or drainage. After eyelid tissue is injured by surgery, reactive edema will appear between cells. Eyelid edema is a normal phenomenon, so there is no need to worry. Using pressure dressing and cold compress can help to alleviate the above phenomenon, but if the swelling is serious and developing, it should be rechecked in time. Although the incision and tissue wound caused by double eyelid incision have been sutured, there is still a small amount of oozing blood. Can use cold compress (ice, cold towel), elastic bandage pressure dressing. At the same time, be careful not to bow your head too much, and don't force your eyes to open or close. If the scar is obviously caused by infection or constitution, local drug treatment, such as steroid hormone injection, is feasible.
