The risks of eyelid surgery, also known as blepharoplasty, include infection, scarring, dry eyes, eyelid malposition, poor wound healing, temporary numbness, and temporary vision changes. There is also the risk of allergic reactions to anesthesia, blood clots, and excess bleeding. The incision lines may become visible and cause an uneven appearance. In some cases, the eyelids can become asymmetrical, or the muscles can be damaged, resulting in drooping eyelids or difficulty closing the eyes. There is also a risk of lower eyelid retraction, which can cause the eye to appear too open. In rare cases, a person may experience vision problems due to damage to the eyelids, nerves, or muscles. It is important to discuss all possible risks with a plastic surgeon before undergoing any facial surgery.
