Bruising Under Eyes Weeks After Surgery. What's the Cause? How To Treat Bruising?

Bruising under your eyes post-surgery is not uncommon. It should go away on its own in a couple weeks, but Arnica topically and or orally may help speed the process.

I know of nothing that hastens the departure of bruising.  I do not think that any of the anti-bruising preparations (eg. arnica) do anything.  Be patient and avoid traumatizing the area.

You most likely had a very bad bruise associated with your eyelid surgery.  It will go away, it just takes time.  Some doctors advocate using IPL to break down the bruise.  I personally have not been very impressed with this approach.  Time is often the best cure.  

Bruising after eyelid surgery can last for a few weeks after surgery. Normally the body just breaks down the blood and absorbs it.

Bruising after eyelid surgery may last several weeks depending upon the patient and technique.  Warm compresses may hasten recovery, arnica may also help.
