Disease description:

Today, when I came to the hospital for double eyelid and eye corner surgery, the doctor suggested I get a blood test. I would like to ask why it's necessary to have a blood test before undergoing double eyelid and eye corner surgery?

Doctor's answer (1)
Dr. Li Fengyong
Blood tests are required before double eyelid and eye corner surgery to rule out any abnormalities in the patient's blood clotting function. Since these procedures involve incisions, abnormal clotting may lead to excessive bleeding during surgery or increased risk of postoperative hematoma, which could negatively affect recovery and surgical outcomes.
