What does a doctor have to do to correct a drooping eyelid if omg?

Droopy eyelid. There are several causes of a droopy eyelid. Your best bet would be to have your eyes evaluated by a board certified facial plastic surgeon.
Ptosis repair. The treatment of a drooping eyelid depends on its cause. If the drooping is due to the stretching or looseness of the eyelid lifting muscle, either a levator advancement procedure (with an incision on the outside) or a mueller muscle/conjunctival resection (incision on the inside of the lid) may be performed under local anesthesia. Congenital drooping may be corrected with a frontalis sling.
