What is Hamra technique surgery? How it evens out under-eye puffiness and hollowing, and what to watch for

Hamra technique surgery involves making an incision below the lash line, then moving—rather than removing—the fat that causes under-eye puffiness into the hollow just below, to smooth out the contour.[1][2]. Because excess skin can also be trimmed away at the same time, this method is used for people with skin sagging (skin laxity).[1]. On the other hand, complications such as the lower eyelid turning outward can occur, and in younger people with minimal excess skin, a transconjunctival approach from inside the eyelid is sometimes chosen instead.[1][3].

How is it different from surgery that just removes fat?

The biggest difference is whether fat is "discarded" or "relocated." With surgery that only removes puffed-up fat, the bulge decreases, but the hollowing and shadow beneath it do not improve.[4].

Removing too much fat can actually make the under-eye area appear more sunken.[1][5]. This led to a broader approach of keeping the fat and relocating it toward the hollow area, smoothing the transition from lower lid to cheek.[1].

Hamra showed a method of relocating fat while maintaining its blood supply.[2]. The step of loosening the membrane that holds fat at the orbital rim has also become the foundation of modern lower-lid surgery.[2].

How do you decide between the transconjunctival approach and the skin-incision approach?

The key factor is whether there is excess skin. The transconjunctival approach is mainly suited for younger people without excess skin whose fat puffiness is prominent.[1].

For people who need skin trimmed away, the skin-incision method is used.[1]. Hamra technique follows this approach, and its hallmark is that it addresses puffiness, hollowing, and skin sagging (skin laxity) all together.

Textbooks emphasize that lower-lid surgery should not overtrim skin and must preserve the lateral support.[6]. How much skin to trim is a judgment that affects both the final result and the risk of complications.

What complications can occur?

In a systematic review of 36 papers on lower-lid surgery overall, no serious vision-affecting complications were reported.[3]. Most complications resolve with observation or corrective surgery.[3].

One complication to watch for is ectropion, where the lower lid turns outward. Across 16 papers, the rate ranged from 0 to 11.3%.[3].

In trials comparing skin-incision procedures, the appearance of white of the eye below the iris occurred in 12% with fat-removal methods and 8% with fat-relocation methods.[3]. Other possible complications include diplopia (double vision), fat granules, bleeding, swelling, and infection.[5].

What are the limits of the final outcome?

Fat-relocation surgery involves detailed steps and takes time for surgeons to master.[4]. Extensive undermining can affect the tissue planes within the eyelid, as has been noted.[4].

Because fat is retained, bulging can become noticeable again over time.[4]. The studies reviewed here mostly report on dozens of cases from single surgeons, and long-term follow-up data remain insufficient.

What should I confirm during a consultation to see if this is right for me?

Check for excess skin, lower-lid laxity, the amount of puffed fat, and the depth of hollowing. These four factors determine whether skin will be trimmed, whether the transconjunctival approach will be used, and whether fat will be relocated or removed.

It is also wise to ask how lateral support will be handled and how ectropion would be managed if it occurs. Which method suits you cannot be decided from an article alone; see a specialist who will examine your eye area in person before deciding.
