Eye Bags and Swelling 8 Months Post-Blepharoplasty

I concur with the other recommendations and highly advise you seek an additional opinion by a board certified plastic surgeon, oculoplastic surgeon, opthalmologist, ear nose and throat physician, and/or internist.
Swelling of the lower eyelids has a variety of causes and surgery is not always the answer:

This includes condition such as thyroid disease.
If the condition is caused by inflammation antiinflammatory medications and drops may be beneficial.

Surgical treatments may produce improvement but other causes should be thoroughly evaluated first. It is difficult to tell if the swelling in your lower eyelids is due to extra fat (surgically treatable) or to edema. If it is the latter you may see improvements with facial manual lymphatic drainage.

It's not unusual for patients to experience swelling following blepharoplasty surgery. In some cases, this swelling may be prolonged and take time to resolve. Although swelling is the most likely explanation for the puffiness of your lower eyelids, other explanations may also be possible. In this case, it's possible that not enough fat was removed at the time of the original procedure.Although your history is helpful, it's virtually impossible to make a specific recommendation without a physical examination or pictures. Even a physical exam might not totally clarify the issue. It's also important to rule out medical conditions, chronic irritation and allergies.In someone who's eight months post-op, it's probably reasonable to consider revisional surgery if the medical workup is negative. For this reason, it's probably reasonable to obtain a second opinion as well.

You may have swelling even after 8 months.  This is unusual but not unheard of.  These vitamins and creams you are using are ineffectual and I would skip them if I were you. 

It is possible some additional fat might need to be removed especially from your left eye.  But it is too early to make that judgment.  As long as you are making some progress, albeit modest, observation should continue. 

It is difficult from the looking up photograph to see exactly what the problem is. It appears as though there is hollowness immediately below the eyes, some retraction of the eyelids, and fullness, perhaps with irregularities from ? fat injection below that at the eye-cheek junction. It appears that your eyes are quite prominent.
Often when prominent eyes are operated on through a lower eyelid (subciliary) incision, the eyelids can pull down, as though seeking a lower position on the spherical globe (eyeball). This can present a problem visually and also functionally as the cornea becomes chronically dry.
The issue you had pointed out, however, was none of the above; rather it was the persistence of fat below the eyes. In your photo this seems to be primarily low down at the eye-cheek junction, and does not consist at all of typical lower eyelid fat that can be removed readily.
Consultations with surgeons skilled in the midface and revision lower eyelid surgery should clear this issue up further.
Although we have written many publications and chapters on your topic, we are never quick to reoperate. Any revision to lower eyelid surgery with lid retraction would typically involve midface advamcent (some type of cheeklift), plus canthopexy. Canthopexy alone can give the eye a severe look with an uptick at the corner but unaltered central roundness of the eye, a characteristic "done" look. Also, grafts such as LiveFill (nontraumatized fascial fat grafts) placed directly in regions of hollowness can help. If there is lumpiness from fat injection, this is usually removed directly.
Patients having revision lower eyelid surgery must be realistic about their outcomes, which are usually subtly better and not completely curative.

Your lower eyelids appear to be very hollow with some bits of retained fat. Like other doctors have commented, it's hard to accurately assess your situation from the one photo in the upward gaze.

The easiest and most cosmetically desirable solution is carefully placed Restylane to the lower eyelids to restore the fullness and camouflage the fat. 

Incidentally, you also seem to have a malar mount (pillow) on the right cheek which can also be camouflaged with filler.

I would give it 4-6 more months. Up to a year or so in some patients, eyelid swelling can exist. These people are rare but theories are that the lymphatics are cut during the surgery and need time to regenerate. The lymph system nornally drains the fluid from our tissues. This may take some time....

It is not very common to have swelling 8 months after surgery. If there is an eye irritant that can cause swelling. If your eyes do not close well, that can also cause swelling. It is hard to tell without examining you. If you have fullness in your lower lids, then perhaps there is still some fat that is prominent and may need to be removed.

I have experienced the bump at the corner of the eye. For some reason this is not uncommon, and is usually (in my patinerts) scar tissue (I use a resorbable suture). A small snip and it is over.
Your sweliing is another story. It may be that there is more fat there, but I would tend to believe your surgeon, as he was there to observe the anatomy. So, going on the assumption that this is swelling, one thing that might help is kenalog (steroid) shots. This must be done based on exam, and carefully, as steroids have possible complication.
Interestingly, if you lay with your head to one side, the lower side due to gravity will tend to swell more.

Kitty,
It is difficult to tell from this picture, but it does appear that you have some residual lower lid fat that needs to be removed. Also, you are looking up so that may be causing the scleral (white) show below your iris. If it is showing from a direct frontal view you may need a canthopexy/canthoplasty procedure. This would raise the outer part of your lid giving you a more cat like appearance, but would correct the scleral show. You may also want to ask what is in the cream that you are using. You may be experiencing a reaction to the cream. And maybe its time for a second opinion.

At 8 months, it is very unlikely that this problem will get better. Most patients see dramatic results within 4-6 weeks following an eyelid procedure. From the picture, it is difficult to tell if you also have some abnormal show of the "whites" or conjunctiva of the eye. This could be corrected at the same time as further fatty removal and lid tightening. Discuss surgery with your doctor. Get a second opinion with a consultation. Our answers may guide you, but examination by a Board Certified Plastic Surgeon or Oculoplastic Specialist would be more helpful.
Topical medications and teas are nice, but they didn't do the trick before the 1st surgery and they won't work now.
