2. Technical Principle
Artificial dermis fundus surgery is to fill the eye platform with artificial dermal tissue through surgery, and then perform Just sew. Artificial dermis is a translucent film made from collagen extracted from rat tail tendon tissue. It can not only fill the skin, but also allow fibrous tissue and blood vessels to grow into it. It is an ideal filling material.
3. Suitable people and taboo people
1) Suitable people: Suitable for all kinds of people who need to have charming fundus.
2) Contraindications
People suffering from eye diseases
Women during menstruation or pregnancy.
People with exophthalmos: People with exophthalmos due to various reasons are best not to undergo this surgery.
Psychiatric patients and patients with other infectious diseases are not suitable for this surgery.
Those who make unrealistic demands.
4. Technical method
Anesthesia: Turn the lower eyelid and inject local anesthetic on the conjunctival surface of the lower eyelid.
Incision: Make a 2-3mm transverse conjunctival incision at the edge of the lower eyelid, and peel it off layer by layer.
Artificial dermis implantation: Transplant artificial dermis tissue of suitable shape into the incision, and perform hemostatic suturing.
5. Artificial dermis
Artificial dermis is collagen extracted from rat tail tendon tissue, and added with glycosaminoglycan ingredients (such as chondroitin 6-sulfate, hyaluronic acid etc.), translucent films made by a variety of methods. It has a mesh structure with a certain pore size inside, and the pore size is between 100 and 150 μm. This pore can facilitate the growth of tissue fibroblasts and blood vessels into it. However, after the artificial dermis is transplanted into the body, its mesh structure will remain. Certain absorption rate and degradation rate, but the rate is relatively slow. In addition, artificial dermis can adhere well to the wound surface, reducing the gap between it and the wound surface, preventing excessive accumulation of body fluids in the gap and inducing serious infection.
6. Risks and complications
1) Infection: Infection may occur in the artificial dermis itself and during the surgery. Once infection is discovered, seek medical attention in time.
2) Blood stasis and hematoma: The exposed tissue is insufficient, and bleeding may be difficult to detect.
3) Silkworm reduction or disappearance: The absorption and degradation of artificial dermal tissue are the main factors.
4) Excessive tension in the skin of the lower eyelid: During the fundus rejuvenation process, if the tissue is sutured too tightly, it may lead to excessive tension in the skin of the lower eyelid.
5) The lower eyelid is sunken.
7. Recovery time
It is normal to experience mild congestion or swelling after surgery. Sutures can generally be removed after 7-10 days, and there may be a foreign body sensation in the short term after surgery. , complete recovery naturally takes 1-3 months, and the specific recovery situation varies depending on individual physiques.
8. Precautions

Do not wear makeup before surgery;
Women should avoid menstrual period.
2) Precautions after surgery
You should also pay some attention to your diet after surgery and avoid irritating foods.
Follow the precautions given by your doctor. 1. Tag: Surgery
2. Technical Principle
Autologous dermal fundus surgery is to surgically remove an appropriate amount of the patient’s own dermal tissue from a hidden part of the body surface and transplant it to The purpose of the eyelid is to achieve the purpose of charming the fundus; if the patient also has eyebags, part of the tissue of the lower eyelid and the dermis can be pushed upward to the eyelid while removing the eyebags, and sutures can be made to form a crotch and remove the eyebags at the same time.
3. Suitable groups and taboo groups
1) Suitable group: Suitable for all kinds of people who need to have delicate fundus, and more suitable for those who also have bags under the eyes.
2) Contraindications
Women during menstruation or pregnancy.
People with exophthalmos: People with exophthalmos due to various reasons are best not to undergo this surgery.
Psychiatric patients and patients with other infectious diseases are not suitable for this surgery.
Those who make unrealistic demands.
4. Technical method
Anesthesia: Turn the lower eyelid and inject local anesthetic on the conjunctival surface of the lower eyelid.
Remove the dermal tissue: Remove an appropriate amount of dermal tissue from a relatively hidden part of the body surface and cut it into shape for later use.
Incision: Make a 2-3mm transverse conjunctival incision at the lower eyelid margin, and peel it off layer by layer.
Autologous dermal transplantation: transplant the cut and shaped autologous dermal tissue into the incision, and perform hemostatic suturing.
5. Risks and complications
Infection: There is a possibility of infection during the surgery. Once infection is discovered, you should seek medical treatment in time.
Blood stasis and hematoma: The exposed tissue is insufficient, and bleeding may not be easy to detect.
The crotch is not obvious: Insufficient filling of autologous dermal tissue is the main factor leading to the crotch.
Loose eyelid skin or excessive tension: During the fundus rejuvenation process, if the tissue is sutured too tightly, it may lead to excessive tension on the lower eyelid skin. If the suturing is improper, it may cause loose lower eyelid skin or even bags under the eyes.
Lower eyelid sunken: The tissue surrounding the lower eyelid platform migrates and grows toward the artificial dermis, causing the lower eyelid tissue to decrease, resulting in sunken.
The size of the silkworm is reduced: The autologous dermal tissue is absorbed by the human body in trace amounts, which may lead to the gradual reduction of the size of the silkworm.
6. Recovery time
The recovery period of this operation is relatively short, and the sutures can be removed 3-5 days after the operation. The specific recovery situation also varies depending on the individual's physical condition. .
7. Precautions
1) Preoperative Precautions

Do not wear makeup before surgery;
Women should avoid menstrual period.
2) Precautions after surgery
You should also pay some attention to your diet after surgery and avoid irritating foods.
Try to avoid makeup and unnecessary collisions in the surgical area to avoid affecting wound recovery.

2. Technical Principle
Autologous fat particle injection fundus surgery is to surgically remove the body's own fat-rich parts, such as the abdomen, buttocks, and thighs. The fat in other places is sucked out by liposuction, and after purification and treatment into pure fat particles, they are injected and implanted into the eye platform to achieve the purpose of making the fundus of the eyes more charming.
3. Suitable people and contraindications
1) Suitable people: Suitable for young patients with elastic skin and thin fat layer under the eyelids.
2) Contraindications
① People suffering from eye diseases: People with congenital amblyopia, chronic conjunctivitis, pink eye, acute infection and other eye diseases.
② People with bleeding tendencies and hypertension, active and progressive diseases of important organs such as the heart, lungs, liver, and kidneys, as well as uncontrolled diabetes and infectious diseases.
③ Women during menstruation or pregnancy.
④ People with exophthalmos: People with exophthalmos due to various reasons are best not to undergo this surgery.
⑤ Mental patients and patients with other infectious diseases are not suitable for this operation.
⑥ Those whose requirements are unrealistic.
4. Technical methods
① Liposuction: Use swelling anesthesia technology in obese areas such as waist and abdomen, thighs, buttocks, etc., and use liposuction equipment to suction the subcutaneous tissue required for transplantation. Fat.
② Fat particle purification: The suctioned fat particles are processed through fat purification technology to extract the fat particles required for injection.
③ Fat injection: Under local infiltration anesthesia, purified fat particles are injected into the subcutaneous fat layer of the eye platform. After surgery, massage and shaping and appropriate pressure bandaging can be performed.
Due to the low survival rate of autologous fat transplantation, if the filling effect is not satisfactory, a second injection of filling can be performed after 3 months.
5. Autologous fat
Autologous fat particles are suctioned adipose tissue. Adipose tissue is composed of fat cells. Adipocytes are mesenchymal cells of adipose tissue. Contains large, liquid lipid-filled membrane vesicles. Think of fat cells as tiny plastic bags that hold a drop of fat. Each adult body contains approximately 30 billion white fat cells, whose function is to store energy in the form of fat cells. Each fat cell contains triglycerides, commonly known as fat globules. When the amount of fat globules becomes larger, the size of fat cells expands, causing obesity; on the contrary, when triglycerides are burned, the cells shrink and the body loses weight.
The reason why transplanted fat can survive is that fat cells can survive a certain degree of trauma, hypoxia, and ischemia. Some scholars believe that the fat obtained through suction is a group of separated fat cells, and a considerable part of the cells remain intact. When these cells are implanted into the body, they can maintain vitality through the infiltration of surrounding tissue fluid and plasma before blood supply is established. .
6. Risks and complications
① Unsatisfactory appearance: caused by insufficient correction or excessive correction of some parts after surgery. It can be injected multiple times, with a small amount being injected first, and a second supplementary injection if insufficient. It is usually given 3 months after the first injection.
② Infection: Infection usually appears 5-7 days after surgery. The infection will cause local redness, swelling, heat and pain. In severe cases, the local skin will be flushed and blue or the pinhole will not heal and pus will flow. When symptoms of infection appear, go to the hospital promptly.
③ Hematoma: Hematoma may form during liposuction and injection. Normally, serious hematoma does not occur.
④ Skin ecchymosis: Skin ecchymosis is caused by blood leakage. Skin ecchymosis generally does not require special treatment and can disappear within 2-3 weeks.
⑤ Local uneven skin: Generally, 3-6 months after surgery, the body itself can adjust itself and can mostly return to smoothness. If there is still unevenness, you need to go to the hospital for correction.
7. Recovery time
After the autologous fat particle injection, you need to rest for 7-10 days. The fat absorption will be obvious within 1-2 months. After 1 month, Then the absorption is basically completed to achieve the desired effect.
8. Precautions
1) Preoperative Precautions
① Do not take drugs containing aspirin within two weeks before surgery. Aspirin It will reduce the coagulation function of platelets;
② Patients with high blood pressure and diabetes should inform the doctor in detail during the initial diagnosis so that the doctor can confirm the surgical plan;
③ Before surgery Make sure you are in good health and have no infectious diseases or other body inflammation;
④ Do not wear makeup before surgery;
⑤ Women should avoid menstrual period.
2) Precautions after surgery
① Congestion and edema around the eyes are common after surgery. Local cold compresses can be used under the guidance of the doctor for two days after the surgery, and hot compresses can be used after the third day. It can reduce congestion and edema and help edema subside.
② Reduce activities as much as possible after surgery to facilitate recovery and swelling, but bed rest is not necessary;
③ Use elastic bandages as much as possible within half a month after surgery to avoid hematoma. Helps tighten skin.
