After full eyelid surgery, if not properly cared for, patients may experience postoperative scarring, loose skin under the eyes, vision loss, and other hazards. 1. Scar growth: Full eyelid surgery is performed by making an incision on the eyelid to remove excess skin and fat, but the trauma area is large, so if not properly cared for, scar growth may occur. 2. Loose skin of eyes: after full eyelid surgery, if you don’t pay attention to daily care, loose skin of eyes may appear. 3. Loss of vision: If you don’t take proper care of your eyes after double eyelid excision surgery, the wound may become infected, causing intraorbital hemorrhage, which will compress the optic nerve of the eyeball, and eventually loss of vision will occur. In order to avoid the occurrence of the above hazards, it is recommended to consult a professional and formal plastic surgery hospital before the operation, the professional doctor to carry out the operation, while the patient should pay attention to the maintenance of the postoperative period.
