Is lower bleph chemosis causing the eyelid retraction? Will it heal? (Photo)

Anabelle,
Chemosis should resolve after a lower eyelid blepharoplasty and steroid drops or an oral steroid dose pack should also help, however chemosis tends not to resolve if allergies or dry eye is not addressed. So be sure to lubricate your eyes with artificial tears (do not get "get the red out" drops). Lower eyelid retraction can happen after surgery and postoperative upward massage can help resolve this issue. It is rare to have lower eyelid retraction be a permanent problem.

Your photos do not show your eyelids and eyes enough to comment specifically on what is going on in your case.  I will say that in general, if chemosis becomes significant or pronounced it can cause changes in the position of the lower eyelid and make it appear retracted or as having mild ectropion (outward turning of the eyelid). Chemosis itself does not cause permanent lower eyelid retraction and when it goes away your lower eyelids should resume their normal position.
