Eyelid surgery, also known as blepharoplasty, is a cosmetic surgical procedure aimed at rejuvenating the appearance of the eyelids by removing excess skin, fat, and muscle from the upper and/or lower eyelids. It can address various concerns such as hooded or droopy eyelids, puffiness, bags under the eyes, and wrinkles. Blepharoplasty can also have functional benefits by improving vision obstructed by sagging upper eyelid skin.
