Why does one eye stay swollen longer after surgery?
Lymphatic drainage, sleep position, dominant-side habits, and small differences in surgical handling all make asymmetric swelling common and usually temporary.
The two eyelids never heal in lockstep. Venous and lymphatic drainage differ between sides, sleep position loads one side more, and no two dissections are identical. A gap of days to weeks between the sides is a normal part of recovery for many patients.
Helping it along, and red flags
Sleeping with the head elevated, avoiding the swollen side when lying down, cold compresses early and warm compresses later, and limiting salt all support drainage. Most side-to-side differences narrow steadily over the first month.
Swelling that grows again, turns red and warm, or comes with pain suggests bleeding or inflammation rather than slow drainage. Since baseline healing speed differs by individual, a persistent or widening gap between the eyes is best assessed by a specialist rather than compared against someone else's timeline.
