Buried eyelid surgery is a procedure in which sutures or polymer sutures are directly buried between the skin and the lid, causing adhesions between the upper eyelid skin and the lid plate to form a heavy eyelid. Buried eyelid surgery is suitable for young people with large lid fissures, thin eyelids, no bloating, no laxity in the eyelid skin and normal tension, and no medial canthus. The benefits of buried eyelid surgery are no incision, simple and quick, low risk, light swelling, quick recovery, and natural results. However, the eyelid effect is not permanent, and the eyelid effect usually lasts 3-5 years, or 10 years if the individual is physically fit and properly cared for. If the individual is not physically fit, if the care is not proper, and if the doctor’s skill level is not high, there may be some harm after a few years of eyelid surgery, as follows: 1) A few years after eyelid surgery, due to sutures and cutting injuries, local tissue adhesions may occur, and the skin of the upper eyelid may become deformed and sunken; 2) As the skin of the eye relaxes and ages with age, the effect of the eyelid may become less and less pronounced. The upper eyelid may need to be repaired by surgical incision, which can increase the cost of surgery and the pain of the patient. In some cases, the sutures do not adhere tightly enough and may fall out. A few buried too shallow threads will drain out. 4. For inexperienced surgeons who over tighten the sutures and lift the upper eyelid muscle resulting in insufficient muscle strength resulting in ptosis
