Introduction
Under normal circumstances, prior to undergoing double eyelid surgery, patients are required to undergo routine urine tests, coagulation function tests, liver and kidney function tests, eye examinations, and infectious disease screenings. Prolonged screen time on electronic devices such as computers and mobile phones may lead to eye fatigue and dryness. It is recommended to take regular breaks, look into the distance, or perform eye exercises to protect eye health.

Generally, prior to undergoing double eyelid surgery, patients are required to undergo routine urine tests, coagulation function tests, liver and kidney function tests, eye examinations, and infectious disease screenings. A detailed explanation is as follows:

1. Routine Urine Test

A routine urine test primarily detects indicators such as protein and red blood cells in the urine to evaluate the health of the kidneys and urinary system. By analyzing the color and odor of the urine, doctors can identify potential urinary system diseases, thereby ensuring surgical safety.

2. Coagulation Function Test

The coagulation function test measures the blood's clotting time to ensure normal clotting ability. This is important for preventing excessive bleeding during surgery. If coagulation function is abnormal, it may lead to increased bleeding during the operation, significant postoperative swelling of the double eyelid, and difficulty in reducing the swelling.

3. Liver and Kidney Function Tests

Liver and kidney function tests assess the metabolic functions of the liver and kidneys by measuring indicators such as transaminase and blood urea nitrogen in the blood. Understanding liver and kidney function helps doctors choose appropriate anesthetic drugs and surgical plans to avoid postoperative adverse reactions.

4. Eye Examination

An eye examination is an important step before double eyelid surgery. It includes using a slit-lamp microscope to magnify the internal structures of the eye and observe whether there is inflammation or other abnormalities in the cornea, lens, etc. In addition, intraocular pressure measurement is performed to assess the risk of glaucoma. These tests help doctors understand the patient's ocular health status and formulate individualized surgical plans.

5. Infectious Disease Screening

Infectious disease screening mainly includes tests for syphilis, acquired immune deficiency syndrome (AIDS), hepatitis B, and hepatitis C. These tests help reduce surgical risks and ensure proper disinfection and handling of surgical instruments and dressings.

Adequate rest is necessary during the treatment period. Patients should avoid prolonged use of electronic devices as much as possible to prevent adverse effects on ocular blood circulation.

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.

How long does the double eyelid surgery procedure take?
Under normal circumstances, double eyelid surgery refers to blepharoplasty. The general reference price for blepharoplasty ranges from 5,000 to 30,000 yuan per session. Improvement is usually visible 1 to 3 months after the surgery. Possible postoperative symptoms include redness, swelling, and pain, which vary depending on individual constitution and recovery status. The duration required for the blepharoplasty procedure needs to be determined based on specific circumstances.

Can individuals with a scar-prone constitution undergo double eyelid surgery?
Scar-prone individuals can generally undergo blepharoplasty, but it is advisable to choose a minimally invasive surgical approach. For example, one may opt for the Korean-style micro-incision double eyelid method or the suture technique. Compared to traditional full-incision blepharoplasty, these methods cause less skin trauma and carry a relatively lower risk of postoperative scar hypertrophy.

Can people with dry eye syndrome get double eyelid surgery?
In general, whether patients with dry eye syndrome can undergo double eyelid surgery depends on the status of their condition. Those with stable病情 and healthy ocular surfaces may proceed with the procedure, but those experiencing acute flare-ups or having ocular surface damage should not undergo surgery until their condition is properly controlled. It is important to maintain adequate eye moisture in daily life, and artificial tears can be used to relieve dryness. Patients should honestly inform their surgeon about their condition before surgery, avoid rubbing their eyes after surgery, and maintain good eye hygiene.

How many years can sutured double eyelid surgery last?
In general, there is no fixed standard for how long sutured double eyelid surgery lasts; typically, the results last from 1 to 5 years. Some individuals may maintain the effect longer, even permanently. The exact duration mainly depends on the suture material, baseline eye conditions, the surgeon's skill, and postoperative care. In rare cases, due to individual physical characteristics, the sutures may be absorbed too quickly or cause an adverse reaction, leading to the loss of the double eyelid within a few months.

Can I wash my hair after getting double eyelid surgery?
In general, it is not recommended to wash your hair within 7 days after double eyelid surgery. You should wait until the surgical incisions have been suture-removed and healed properly before washing your hair. Double eyelid surgery is an invasive procedure, and the incision sites are typically covered with gauze post-surgery. Before the stitches are removed, the incisions remain unhealed. During hair washing, water and shampoo may seep through the gauze and come into contact with the incisions, potentially causing bacterial infection, leading to redness, swelling, or pus formation.

Can I eat cooked onions after getting double eyelid surgery?
In general, after double eyelid surgery, it is advisable to temporarily avoid consuming cooked scallions. Although the pungent components of scallions are reduced after heating, their volatile oils and sulfides remain irritating and may induce local capillary dilation, increase the risk of exudation, and thereby delay epithelialization of the incision site. Clinically, it is routinely recommended to follow a mild, low-salt, and low-pigment diet within the first two weeks postoperatively.
