Seven Things People Get Wrong About Under-Eye Fat Repositioning: A Fact Check

Sunken eyes, lost aegyo-sal, a changed eye shape, permanent sutures, "you only get one chance" — the claims that circulate in forums and comment sections, checked one by one against what the surgery actually does and why.

September 7, 2026 · ST Journal

Why the comment section is the wrong place to diagnose your eyes

A patient posts a photo one week after under-eye fat repositioning in an online forum. The bruising is still there — completely ordinary at day seven — and within hours strangers have replied that the surgery was botched and that she should find another surgeon immediately. This is a real pattern, and ST hears the fallout from it at consultation constantly. The people answering are almost never doctors, they carry no responsibility for the advice, and the person absorbing it is left anxious over something that would have resolved on its own. What follows is a fact check of the claims that come up most often, written so that the reasoning is visible, not only the verdict. Read forums as reference, not as diagnosis, and put the actual questions to the surgeon who examined you — that is what they are there for.

Myth: the eyeball sinks or the eye stops working properly

This fear comes from confusing repositioning with removal. Fat repositioning does not take fat out of the socket; it moves the fat that has pushed forward down over the bony rim into the tear trough. The cushion of fat that actually supports the eyeball from behind is a much larger reserve and is not touched. Only the exposed anterior fat — the part you can see as the bag — is handled, and the muscles that move the eye lie outside the field of the surgery. In two decades of performing this operation ST has not encountered a case of the eye sinking or losing function from repositioning, and anatomically it is hard to construct how it would happen. A related fear is that the upper eyelid hollows out after lower-eyelid surgery. That did happen in an earlier era, when some surgeons removed fat aggressively, including the deep fat behind the bag; the eye could then settle downward and the upper lid would look emptier. Repositioning preserves the fat, so this is not part of it. When a patient notices a hollow upper lid after surgery, it is almost always a hollow that was already there: the lower lid used to bulge next to it, and once the lower lid is smooth, the upper hollow reads as twice as deep. If it bothers the patient, the answer is fat placed carefully into the upper fat compartment — not fat injected at random under the skin.

Myth: your aegyo-sal disappears, or becomes uneven

It helps to define the term. Aegyo-sal — the soft roll directly under the lashes — is made of the tarsal plate, the orbicularis muscle over it, and the skin. It is not fat. Before surgery, in a person with a prominent bag, the orbital fat sits directly beneath that roll and the two blend into one large mound, so the aegyo-sal can look bigger than it is. When the fat is moved down, the roll that was always there simply becomes visible on its own. Nothing was removed from it; the surgery does not cut muscle, tarsus, or skin in that area. The same logic explains the complaint that the aegyo-sal became asymmetric: if the two sides were slightly different to begin with — which is common — the fat used to mask the difference, and now it shows. What is fair to say is that some patients preferred the fuller look they had when fat and aegyo-sal were fused. That is a preference, not a loss, and it can be addressed around the three-month mark once the tissue has settled, with a muscle-roll technique, a small fat graft, or filler.

Myth: the eye shape changes, and dark circles get worse

In the large majority of cases where a patient feels their eye shape has changed, the cause is swelling. The two lower lids swell and resolve at different speeds, and while one is fuller than the other the eye can look pulled, rounder, or slightly different in its line. As the swelling leaves, the original shape returns. The exceptions are real but specific: scar contracture inside the conjunctiva after a transconjunctival approach, or over-removal of skin in an incisional approach leading to ectropion. Both are problems of how the surgery was executed, not consequences of repositioning itself, and both tend to improve with time or are correctable. The claim that repositioning makes dark circles darker has a similar structure. Every case ST has examined where a dark circle looked worse afterward turned out to be one of two things — fat was removed rather than repositioned, leaving a hollow shadow, or the patient did not have enough fat to fill the trough and no graft was added to make up the difference. A repositioning that moves the fat into the shadow does not create a deeper one. A result can fall short of expectation; being worse than before is a different claim and it is not what the procedure does.

Myth: permanent sutures cause trouble, and you only get one chance

Patients who know that ST fixes the fat with non-dissolvable sutures sometimes ask whether the thread will show, cause infection, or appear on an X-ray. The comparison they have in mind is buried-suture double eyelid surgery, where a knot sits close to the skin and can occasionally become visible or irritated. Fat fixation is a different depth entirely: the sutures anchor the fat to the periosteum on the bone, beneath the muscle, with layers of tissue above them. They cannot surface. Infection after any surgery is a question of bacteria during the procedure, not of the suture material, and the sutures are not visible on X-ray or CT. The second half of this myth — that repositioning can only ever be done once — is also untrue. Revision is possible a second, third, and even fourth time, through the conjunctiva again or through a skin incision, regardless of which route was used the first time. What is true is that each revision carries a somewhat higher complication risk than the one before, and the tissue is less forgiving, which is why later revisions belong with an experienced surgeon rather than being a reason to avoid them.

Myth: it creates an epicanthal fold, and grafted fat damages the eye

Some patients notice a more visible fold at the inner corner of the eye after repositioning and assume the surgery created it. The fold was there before. The medial fat compartment bulges right next to the inner corner, and that bulge was covering part of the fold; once the fat is moved down and the area flattens, the fold stands alone and reads more clearly. For most people this is minor. The exception is a fold that connects downward into the tear trough — you can check by pressing the bulge with a cotton swab and seeing whether a continuous line runs from the corner into the trough. In that pattern ST recommends addressing the fold in the same plan, either by extending the incision inward in an incisional approach or with a separate epicanthoplasty, and a small amount of fine fat can also soften it. Finally, the fear that fat grafting under the eye damages the eye muscles or leaves lumps: the anterior fat that is grafted has no connection to the muscles that move the eye, the blunt cannula used cannot puncture a vessel, and lumps come from placing fat into the moving muscle layer — which is exactly why ST places grafted fat inside the fat compartment rather than under the skin.

Article FAQ

At one week, bruising, uneven swelling, and a slightly changed eye line are all expected. None of it is a basis for judging the result, and forum replies carry no responsibility for being right. Send the same photo to the surgeon who operated on you. If there is a genuine warning sign — severe one-sided pain, a bulging sensation, or pain that starts days after surgery and worsens — that is what needs an urgent call, not a comment thread.

No. The aegyo-sal is muscle, tarsal plate, and skin, and the surgery does not remove any of it. What changes is that the fat which used to merge with it visually is moved down, so the roll shows on its own. If you preferred the fuller merged look, it can be enhanced around three months after surgery.

Yes. Revision is possible whichever approach was used the first time, and patients on their second or third revision are not unusual. Because each revision is technically harder and carries somewhat more risk, later revisions should be done by a surgeon with substantial revision experience.

After LASIK, LASEK, or cataract surgery, ophthalmologists generally consider the eye ready for eyelid surgery from about one month; ST prefers one to two months. After fat repositioning, ST recommends waiting around two months before any eye surgery, because the lids are still healing and are held open during those procedures. The order does not matter; only the recovery interval does.
