According to the information you provided, Koreans have been positioning their double eyelids at three o'clock for almost three years, and now there are almost no double eyelids. Re-cutting or catgut embedding surgery can be considered to repair double eyelids.

In this case, it is recommended to consult a professional doctor or plastic surgeon to understand the specific surgical plan and possible risks. Generally speaking, if the Korean three-point positioning surgery was used before, because of the fixed incision and scar on the eyelid, it may affect the reoperation to some extent. Therefore, it is necessary to carefully consider when choosing the operation method, and choose the operation method that suits you according to your personal situation and doctor's advice.

If you choose total excision, the doctor will remove the original scar and skin tissue according to your personal situation and form a new double eyelid. This method has a long-lasting effect, but it takes a long time to recover and has certain surgical risks. If you choose to do catgut embedding surgery, you don't need to cut the skin, but sew the skin and eyelid tissue together with absorbable thread to form double eyelids. This method has a short recovery time, but the effect may not last as long as total resection.

In short, for the choice of double eyelid repair surgery, it is necessary to fully understand the risks and effects of the operation and make a decision under the guidance of a doctor. At the same time, we should pay attention to personal eye care, maintain healthy living habits and promote eye health.
