What medical examinations are required for double eyelid surgery?
Generally, double eyelid surgery refers to blepharoplasty. Before undergoing blepharoplasty, routine preoperative examinations include a complete blood count, coagulation function test, liver and kidney function tests, infectious disease screening, and specialized eye examinations. Detailed explanations are as follows:

1. Complete Blood Count (CBC)
A complete blood count assesses the patient for anemia, infection, or thrombocytopenia by measuring the number of red blood cells, white blood cells, and platelets. This test ensures normal platelet levels to prevent unexpected bleeding during surgery.
2. Coagulation Function Test
Coagulation function testing measures blood clotting time to ensure normal clotting function and prevent excessive bleeding during surgery. This test evaluates the quantity and activity of clotting factors, ensuring an effective clotting mechanism and reducing surgical risks.
3. Liver and Kidney Function Tests
Liver and kidney function tests evaluate the metabolic functions of the liver and kidneys by measuring indicators such as blood transaminases and blood urea nitrogen. Liver and kidney function can affect the metabolism and application of anesthetic drugs used during surgery. Therefore, these tests help doctors choose appropriate anesthetics and surgical plans to avoid postoperative adverse reactions.
4. Infectious Disease Screening
Infectious disease screening includes testing for syphilis, hepatitis B, hepatitis C, and other infectious diseases to reduce surgical risks. These diseases may be transmitted through blood, so preoperative screening helps protect both patients and medical staff.
5. Specialized Eye Examination
Specialized eye examinations include visual acuity testing, eyelid examination, and eye examination. Visual acuity testing assesses vision problems such as myopia, hyperopia, and astigmatism; eyelid examination observes eyelid shape, degree of skin laxity, and presence of inverted eyelashes; eye examination checks eye position, movement, and conditions such as dry eye syndrome or conjunctivitis. These tests help doctors understand the patient's ocular condition and formulate an individualized surgical plan.
In daily life, it is recommended to consume foods rich in vitamins A, C, E, and zinc, such as carrots, spinach, citrus fruits, and nuts, which help protect the retina and prevent eye diseases.
