The immediate swelling after eyelid surgery may last approximately a week or 2, depending on several factors. After this initial healing period, swelling is still present, but usually only noticeable by the patient. The very last tiny bit of swelling takes several months to gradually abate.
It’s possible to have swelling in areas of the face and eyes adjacent to the surgery site, even though plastic surgery was not necessarily performed in those areas. This extension of facial swelling is due to gravity and the natural movement of fluid in the tissues. In addition, keep in mind that the eyelids, face, and nose are very sensitive to swelling from other factors, such as allergies, diet, hormones, gravity, sleep, etc.
