Eyelid surgery or Blepharoplasty is a surgical procedure that treats excess skin and orbital fat around the eyes. Whether that is a congenital problem (born with) or caused by aging process of the skin. That gives a sagging and baggy look to the eyelids due to the lack of elasticity in the skin, and fat accumulation under the eye.
This procedure is usually used for cosmetic reason. But it is also used for functional reasons to improve sight in older people whose sagging upper eyelid affects their vision. In both cases eyelid surgery plays an important role in face rejuvenation and gives a self-confidence to the patient.
