Help! Did my quad blepharoplasty go wrong? 10 days post-op.

As you state, you are very early in the healing process.  You have some swelling, but not too bad.  You appear to have some ptosis in the right upper lid, so that eye appears smaller.  You did not have a ptosis pre-op, so this may just improve with time.  The only other thing I see at this point is the left lower lid is pulling down a bit in the corner.  This side is more bruised and swollen, so at that resolves, the lid may come back up.  Warm compresses and a little massage upward will help.  

I know it can be distressing to have asymmetry after eyelid surgery but do not worry. It is very common and usually resolves. This is because you may have increased bruising or swelling on one side or the other. Trust the process and I would not make any definite judgment till at least 6 weeks, and really it usually takes longer to see the final result. Hope this helps.

It is very difficult to assess asymmetry of the eyes after blepharoplasty in the initial few weeks.  He also have to notice the right eyebrow that is higher than the left.  Over the next few weeks the asymmetry should get better.  If it is not better in 4-6 weeks then you should get a second opinion for possible correction.RegardsDr. J
