My eyelid is always droopy after upper eyelid ptosis surgery. Any suggestions? (photo)

It can be tough to get 100% symmetry with any surgery, and especially when only doing one side.  However you have only a very slight asymmetry at this point, with maybe a 1mm difference.  And you are only 2 weeks post-op.  So this is an excellent result.  As you heal more there is a very good chance that the lid will lift up a bit more and you will be even more even.   

Your left eyelid is still probably swollen. Give it 2 more weeks to heal. Scar tissue often tightens and the eyelid may lift higher. On the other hand, from the photographs your left eyelid seems to be in good position. The right upper eyelid looks slightly higher than normal and your right lower lid looks a bit lower than normal. See your oculoplastic surgeon for follow up in 3 weeks. Good luck. 

It certainly looks like you have had a very acceptable result considering you are only 14 days.  You do have some asymmetry of you orbital region which you may be seeing as a difference.  Swelling usually takes 6-8 weeks to fully resolve.  If you are at all concerned by all means give your surgeon a call and set up an appointment for a follow-up.  Even if it's only to be reassured.  Good luck

Adjusting lid height can be difficult. I would give it at least another month or two before deciding if further surgery is needed.  Of course myesthenia Gravis is always in the back of our minds. See what happens to the lid height in a few months then reevaluate as needed 

Without before posted photo to compare I guess is the result to me appears very acceptable. ////////////
