Upper blepharoplasty too much fat removed, 12 months post op. Any chance my own fat will move forward and fill the hollowness?

Unfortunately, it is unlikely that fat (from further back in the eye) will move forward over time. In fact,  you should expect more fat loss and hollowness with increasing age.  Too often, surgeons remove all the fat around the eye in an attempt to achieve a more "dramatic" result. This can leave the patient looking "skeletonized" and sunken.  This problem can be treated with fat injections using donor fat taken from your abdomen, hips or thighs. The fat is injected using a small blunt cannula and takes only a few minutes. Alternatively, you can use one of the popular HA fillers. Find a surgeon with experience with fat injections and the treatment of hollow eyelids.

 

The
key element here is prevention. Modern blepharoplasty does not remove significant, if at all, fat from the upper and lower bleph. Blepharoplasty
surgery allows for reposition or reshaping. In patients that have too much fat
removal, one can restore it with the use of fillers or use of fat restoration. This should be done
in the hands of a Board Certified Plastic Surgeon with expertise in Oculoplastic
surgery.

The answer is "highly unlikely".  In fact, more fat loss is expected from the upper eyelid area as one ages. The good news is that we can fill the area with either own fat (taken from the belly or thighs) or synthetic fillers (which are very safe).  See an oculoplastic surgeon.
