Introduction

Under normal circumstances, "doing double eyelids" refers to undergoing double eyelid surgery. Blood may be drawn before the surgery to determine the patient's blood type, screen for infectious diseases, assess coagulation function, check for anemia and diabetes, and test for allergic reactions. After the surgery, the eyelid area should be kept clean and dry. Avoid getting water on the incision site when washing the face to prevent infection.

Generally, double eyelid surgery refers to blepharoplasty, which is a surgical procedure that creates adhesion between the eyelid skin and the tarsal plate or muscles, forming a crease in the eyelid. The usual reference price for blepharoplasty ranges from 2000 to 6000 yuan per session. Improvement is typically noticeable 3-4 weeks after surgery, although symptoms such as localized swelling and pain may occur. Blood tests before blepharoplasty may be conducted to determine the patient's blood type, screen for infectious diseases, assess coagulation function, check for anemia and diabetes, and detect potential allergic reactions. Detailed explanations are as follows:

1. Determine the patient's blood type

Blood tests help doctors identify the patient's blood type, which is a routine preoperative preparation. During surgery, knowing the patient's blood type ensures that the correct blood type can be provided if a blood transfusion is needed, avoiding transfusion reactions.

2. Screen for infectious diseases

Blood tests allow doctors to determine whether the patient has infectious diseases such as hepatitis B, acquired immunodeficiency syndrome (AIDS), or syphilis. These conditions may increase the risk of infection during surgery or affect postoperative recovery. Therefore, understanding the patient's infectious disease status in advance helps doctors take appropriate preventive measures to ensure surgical safety.

3. Assess coagulation function

Blood tests allow doctors to evaluate the patient's hemostatic capacity. If coagulation function is abnormal, it may lead to excessive bleeding or difficulty in hemostasis during surgery, increasing surgical risks. Therefore, assessing coagulation function helps doctors adequately prepare for possible bleeding during surgery.

4. Check for anemia and diabetes

Anemia may reduce blood viscosity and impair wound healing, while diabetic patients are more prone to postoperative infections and slower wound healing. Blood tests allow doctors to promptly detect these issues and make necessary adjustments and treatments before surgery to ensure surgical safety and effectiveness.

5. Detect allergic reactions

Some patients may be allergic to certain anesthetic drugs or surgical materials. Blood tests for allergens enable doctors to understand the patient's allergic status in advance and take appropriate preventive measures before surgery, such as changing anesthetic agents or using alternative sedation methods, to avoid allergic reactions.

After undergoing blepharoplasty, the eyelid area should be kept clean and dry. Avoid getting the wound wet when washing the face, and refrain from touching the wound area with your hands to prevent infection.

Is it attractive for males to have fully incised double eyelids?

In general, a full-incision double eyelid procedure involves making an incision on the upper eyelid, removing excess skin and fat, and then attaching the eyelid skin to the tarsal plate at a specific height to create a double eyelid crease. Whether a full-incision double eyelid looks good for males depends on individual facial features and whether the surgical design aligns with male aesthetic characteristics. There is no absolute answer, but overall, the key is to achieve a natural and harmonious appearance.

Can individuals with a scar-prone constitution undergo double eyelid surgery?

Double eyelid blepharoplasty creates a double eyelid fold by making an incision on the upper eyelid, removing excess skin and fat, and attaching the eyelid skin to the tarsal plate. The general reference price for double eyelid blepharoplasty is 3000–8000 yuan per session. Noticeable improvement is usually observed within 1–3 months, although symptoms such as swelling and pain may occur. Individuals with a scar-prone constitution are advised against undergoing this procedure.

Is droopy eyelid corrected by a brow lift or double eyelid surgery?

The choice between eyebrow excision (brow lift) and full-incision double eyelid surgery for ptotic eyelids depends on individual circumstances. For younger individuals with mild ptosis, full-incision double eyelid surgery is generally recommended to improve the condition. However, for older individuals or those with severe eyelid laxity, eyebrow excision is typically advised, as it can reshape the eyebrows and restore tightness to the eyelid skin.
