Problem analysis: Our patients also have swollen eyes and tearing after double eyelid surgery and eye bag surgery. The reason is that the surgery exposes part of the cornea that was originally covered by the eyelids, and the cornea is the most densely distributed nerve in the human body. The natural reaction of this part is to protect the eyeball and secrete more tears. Of course, if there is no improvement in 20 days, you need to go to an ophthalmologist to check whether the cornea is damaged.
