Upper eyelid lift surgery is a procedure derived for eye defects with upper eyelid ptosis problems and is usually performed in conjunction with a full eyelid cut. Patients with upper eyelid ptosis problems are not suitable for the buried, three-point approach, which is difficult to solve the underlying problem. The specific risks are as follows: 1. Overcorrection and incomplete closure of the upper eyelid complicated by keratoconjunctivitis: caused by excessive removal of the levator muscle, overestimation of the function of the levator muscle before surgery, or excessive excision of the upper eyelid skin; 2. Injury to the levator muscle and upper rectus muscle; 3. Undercorrection: mainly due to insufficient removal of the levator muscle, conservative operator, inadequate separation, accidental tissue injury, and pull-out or disintegration of the fixation sutures; 4. Upper 4. Fornix conjunctiva prolapse and intraoperative orbital fat dislodgement: this may be due to a wide separation of the superior fornix conjunctiva, loss of conjunctival support and prolapse of the separated conjunctiva without suture repair, as well as postoperative bleeding or fat prolapse into the subconjunctiva or loose conjunctival sutures; 5. In the case of severe ptosis, the skin incision is too low, the lid margin is pulled after suturing, or the upper lid levator is fixed too low and tight to the front of the lid plate; 7. Hematoma and infection occur during surgery. It is recommended that candidates visit a regular hospital to avoid surgical risks in order to obtain satisfactory treatment results.
