Repositioning or grafting
How does under-eye fat repositioning differ from fat grafting?
Repositioning moves nearby orbital fat toward the hollow while keeping an attachment. Fat injection adds tissue harvested from another area, such as the abdomen or thigh. The source of the fat and how it is transferred are different.[1][2]

Does using your own fat make these the same procedure?
Both use your own tissue, but the connection to the original tissue differs. In attached repositioning, orbital fat is mobilised beyond the lower orbital rim. Injected fat has been separated from its donor area, processed and transferred to the receiving tissue.[1][2]
When the consultation uses terms such as transfer, grafting or redistribution, ask where the fat starts, whether it remains attached and where it will be placed. Following the tissue through those steps is more informative than relying on a short operation name.
Which area does repositioning address?
When a projecting bag sits above a tear-trough hollow, nearby orbital fat can be redistributed across that boundary. Releasing attachments around the orbital rim makes a space for the fat and helps address the transition from the eyelid into the cheek.[1]
The available fat, its reach and the selected technique shape the treatment area. Adding volume broadly across the cheek is a different task from redistributing tissue along the lower orbital rim. Ask the surgeon to identify the intended destination of each part of the transfer.[1][3]
Where does injected fat come from?
The review of periorbital fat grafting describes donor areas including the abdomen, hip and inner thigh. Harvesting, processing and placing the tissue are separate steps. The donor area belongs in the surgical plan and its aftercare arrangements.[2]
Grafting adds volume to a hollow. If the proposal includes both the lower eyelid and cheek, ask which feature each receiving area addresses. Whether projecting orbital fat also needs removal or redistribution is a separate part of the assessment.[1][2]
| Feature | Attached fat repositioning | Harvested fat injection |
|---|---|---|
| Fat source | Orbital fat | A donor area such as abdomen or thigh |
| Transfer | Moves attached fat beyond the orbital rim | Injects processed tissue into the receiving area |
| Planning focus | Relationship between the bag and tear trough | Extent of hollowing and added volume |
| Written details | Release and fixation method | Donor area and injection area |
Attached repositioning uses local orbital fat; injection introduces tissue harvested from a donor area.[1][2]
Can excised orbital fat also be used as a graft?
Yes. In a 2026 prospective study of extended transconjunctival surgery, excised orbital fat was fashioned into free grafts and placed along the orbital rim. The study included 200 patients, and 96% also received midcheek fat grafting. This differs from moving an attached fat pedicle.[4]
It also differs from an operation consisting only of injected donor fat. If a proposal says that it uses orbital fat, clarify whether the tissue remains attached or is excised first. Ask whether a separate donor area is involved and how each graft is placed.
What does the fat-grafting evidence show?
A 2021 systematic review gathered 39 studies with 4,046 cases involving eyelid and periorbital fat grafting. Most studies were case series, with differences in the procedures and outcome assessment. Check whether the evidence concerns the lower eyelid specifically or other areas around the eye.[2]
The review could not pool the available volume-retention results. The amount injected should therefore not be treated as a precise prediction of the settled volume. Ask how the result will be assessed and what process would be used to consider further treatment.[2]
What should a combined plan explain?
Ask for separate descriptions of the hollow treated by repositioning and the area treated by injected fat. A statement that both are being performed leaves their individual purposes unclear. Include donor-site care, medication and review arrangements in the discussion.
If redundant skin is a major concern, moving or adding volume does not describe the entire surgical question. Skin treatment needs its own assessment and explanation. Separating fat, skin and support procedures makes the scope of a combined plan easier to understand.[1][3]
At a Seoul consultation for orbital fat treatment, describe the areas that concern you from the front and at an angle. Request separate entries for repositioning, harvesting, injection and skin treatment in the written plan and quotation. That also makes later changes to the proposal easier to follow.
Common questions about moving and adding fat
Does every repositioning operation need fat injection?
No. Injection is a separate procedure considered according to the hollow and cheek findings. Ask what each proposed operation is meant to address.[1][2]
Is using removed orbital fat the same as attached repositioning?
No. Excised orbital fat can be used as a free graft, which should be distinguished from attached fat transfer.[4]
Is there a fixed retention rate for injected under-eye fat?
The 2021 periorbital review could not pool volume-retention findings. A shared retention percentage should not be assumed.[2]
