Bags under the eyes/bags under the eyes, also known as eyelid bags, usually refer to the signs of sagging and edema of the lower eyelid skin caused by slack skin and more fat accumulation in the orbital septum. It usually occurs in middle-aged and elderly people after the age of 40, and can occur in both men and women. Eyebags are the result of degeneration and relaxation of orbital fat, orbital septum fascia, orbicularis oculi muscle and lower eyelid skin in middle-aged and elderly people. For the treatment of pouch, different clinical types should adopt different surgical methods. Laser blepharoplasty is a new surgical method with the development of laser medicine. Compared with the traditional operation, the operation effect is good, the complications are few and the recovery is quick. Internal incision blepharoplasty is a popular blepharoplasty at present, which removes eye fat through a small incision in the lower conjunctival sac. Therefore, there is no incision on the skin surface, which is very popular with young patients. This method is mainly suitable for orbital septum fat protrusion, that is, typical eye bags caused by orbital septum bulge, without skin relaxation and lower eyelid skin wrinkles.
