Japanese style scarless eyelid surgery involves making a small incision of about 1mm in the lid skin, partially removing the orbital fat from within the incision, and then lifting the upper eyelid muscle and lid plate. Therefore, Japanese style scarless double eyelid is not completely scarless and is a type of incision double eyelid surgery, which leaves traces even though the incision is small. This type of surgery has the advantages of minimal trauma, quick recovery, and natural-looking results. However, there are certain hazards associated with Japanese seamless double eyelid because it is a form of partial incision double eyelid. The surgical principle is the same as Korean three-point, except that the surgical incision is more on the minimally invasive side. Because of its smaller incisions, the surgeon’s room for maneuvering is more limited and it is not suitable for candidates with thick upper lid fat, heavy swollen eyes, or severely lax upper lid skin. As people age, the laxity of the eye skin becomes more and more serious, the upper eyelid crease tends to disappear, and the eyelids become narrower and narrower, or even develop into “inner pairs”, which may require double eyelid surgery again. Therefore, for the type of double eyelid surgery, candidates need to be guided by an experienced physician to understand the pros and cons of the surgery and choose the most suitable method for themselves.
