The cosmetic eye surgery that most people choose is often referred to as “double eyelid”, also known as blepharoplasty, and is by far the most numerous of the various cosmetic surgery procedures. So what is there to know about blepharoplasty? Why do I need to have double eyelid surgery? Aside from personal aesthetic differences, blepharoplasty makes the eyes appear larger and more “electric”, makes the person appear more refreshed, removes loose skin from the upper eyelids, uplifts the eyelashes, and gives the candidate a lot of aesthetic points. What are the surgical options for double eyelids? The main types of eyelid surgery that are commonly used today are the buried liner method, the three-point minimally invasive method, and the incision method. Experienced surgeons will choose different procedures for different situations. At present, the market often promotes the concept of “Korean double eyelid”, please be clear, these concepts are only the market operation needs, the real effect, or to return to the level of the physician, different from person to person, personalized design. The main complications after double eyelid surgery are: asymmetry of both eyes (the most common), due to swelling, etc. Usually wait for 2 months before checking again and can be surgically repaired. Ptosis, sometimes due to anesthetic paralysis to the levator muscle, which can be recovered after surgery. Localized sunken eyes, usually because too much fat has been removed. Double eyelids that are too wide, commonly known as European eyes, are more difficult to repair. It is normal for the eyelids to become shallow after the swelling has subsided. If they slowly become shallow after six months, it means that the buried line has fallen off or the lid has become loose from the skin scar, which requires another surgery to adjust the scar, but generally the eyelid skin is not easily scarred and can be surgically repaired if necessary. Other less common conditions include dry eye and visual blindness. In addition to double eyelid surgery, other common cosmetic eye surgeries include inner and outer canthoplasty, commonly known as canthopexy, and blepharoplasty. There are many surgical methods, but the overall principle is to avoid scarring at the inner corner of the eye as much as possible, because it is very easy to leave scars at the inner corner of the eye, which affects the beauty and is difficult to repair. The outer corner of the eye can be opened up to a limited number of people, and it is also easy to leave scars, or cause eyelid deformation, and the long-term results after surgery are related to the physician’s choice of surgery and level, so it is recommended to choose an experienced professional physician to operate and choose carefully. Eye bag surgery is generally divided into two types: internal incision and external incision, internal incision is the conjunctival approach, which is suitable for young patients without skin and orbicularis muscle relaxation, external incision is the skin approach, which is suitable for patients with skin and orbicularis muscle relaxation, beauty seekers should pay attention to the difference between eye bags, sleeping silkworms, black eye circles, etc., and choose the treatment method that suits them. The surgery should avoid removing too much fat, resulting in local depression, or removing too much skin, resulting in eyelid turning down. For some patients with obvious tear troughs, eye bag surgery combined with tear trough fat filling is a meaningful choice.
