To determine whether a person is a keloid or not is generally based on 3 things: the nature of the keloid, the cause of its formation, and the location of the keloid. If keloids are present on the body, the person is keloid. If hyperplastic scarring occurs, it is determined by the cause of its formation: a wound that has been carefully stitched by a surgeon, has not become infected, and has healed in one stage, and then forms a hyperplastic scar at a later stage, is determined to be keloidal. If the wound has not been sutured by a surgeon, or if it has been sutured but becomes infected and forms a hyperplastic scar after healing, or if a wound that has healed after a dressing change after a burn heals and develops a hyperplastic scar after healing, these cases are not certain to be keloidal. Keloid scarring occurs in a variety of areas and is related to the nature of the surgery performed. Since the skin of the eye is relatively thin and has a much richer blood supply than other parts of the skin, scarring is usually not obvious after surgery. Double eyelid surgery by incision method, external eye bags and eyebrow cutting surgery will prolong the congestion time of the incision, and even mild hyperplasia will occur, but with the passage of time, basically only a thin mark will be left, which will not be very obvious; double eyelid surgery by submerged thread method or three-point minimally invasive method, such as non-infection, postoperative recovery is good, and the scar will be almost invisible; internal incision of the eye bag surgery, as the incision will only be made through the mucosa and no scar will be formed, so it can be done with confidence. Therefore, it can be done without worry. Even if there are visible scars on other parts of the body, it is possible to determine whether or not you can have oculoplastic surgery based on the circumstances. In our experience, it seems that most scarring is misdiagnosed and therefore the vast majority of people can have oculoplastic surgery.
