Can anything be done about the remaining sagging in inner corners of my eyes after eyelid surgery 12 weeks ago? (Photo)

From your photos I can see your concern of a little extra skin at the inner corners of the upper eyelids. This could be easily removed. Talk to your surgeon.

Modest amounts of loose in redundant skin of the upper lids such as those shown in the photograph would respond nicely to CO2 resurfacing.

Your surgeon did you a disservice.  You may have asked for blepharoplasty and you got blepharoplasty (skin removal).  What you needed was to have your ptosis repaired.  This still needs to be done.  I recommend getting assessed by a fellowship trained oculoplastic surgeon and seeing what they suggest. 

There are a few things that I notice here.  You have ptosis which was not corrected at the time of surgery, so your eyelids are in a low position.  If you don't mind this then I would leave that alone.  You have very little fat in the upper lids, so you have a deep sulcus.  You also do not have a good eyelid crease, so you have some bunching skin here.   A revision could be done to try to make a more definitive crease, and possibly trim a little skin.  You might also consider some filler to the deep sulcus to help give some support to the lid and make it look less hollow.  

At three months after surgery, any swelling from surgery should be gone. The excess skin in the nasal end of the eyelids does seem to be more than is desirable. Since your eyeball is nice and open, meaning that it is more prominent than someone who has deeper set eyes, the truth is that it takes more skin to close your eye, especially when you are asleep than someone with deeper set eyes. Having a little more skin may be necessary to keep you from having dry eyes. Now that the swelling is down, discuss with your surgeon whether a pinch of skin can be removed safely to maximize your cosmetic result without compromise of the functional task of preventing dry eye syndrome.John Standefer MD

You had a difficult problem, and do have a small amount of excess skin that remains.  Discuss your concerns with your original surgeon - removal of the remaining skin can be removed fairly simply.  Hope this helps!

You have very nice results with an original difficult very hanging upper lid. It really depends upon what you are looking for.  A small trim of the inner area may be reasonable in the future if desired.

Talk to your surgeon.  He/she should be able to excise a little more skin under local anesthesia to obtain the result you desire.  Good luck.  Donald R. Nunn MD  Atlanta Plastic Surgeon
