Transconjunctival Blepharoplasty: The Scarless Lower Eyelid Approach and Its Limits

Transconjunctival blepharoplasty is a lower eyelid operation that reaches the fat pads through an incision inside the lid, on the conjunctiva, so there is no external scar and a lower risk of the lid pulling down than the approach that cuts through the skin. It is aimed at the bulging fat that makes under-eye bags; on its own it does not remove loose lower-lid skin¹.

When my lower lids were done, the part that surprised me was how little there was to see afterwards: no line under the lashes, nothing to point to, and yet the puffiness that had sat there for years was gone. This is the plain version of why that is possible, and where its limits are. For how the lower lid is treated overall, and the choice between working from inside and from outside, start with lower blepharoplasty.

What is transconjunctival blepharoplasty?

It is the “inside the lid” way of doing lower blepharoplasty: the surgeon makes a small incision on the conjunctiva, the moist pink lining of the inner eyelid, and reaches the herniated fat pads through it without touching the outer skin. The three lower fat pads can then be reduced or, increasingly, repositioned over the bony rim².

The whole point of the route is what it avoids. Because the incision is hidden inside the lid, nothing is visible on the skin once it heals, and the conjunctiva usually seals on its own without stitches to remove. It is the standard choice when the problem is fat rather than skin, which is most under-eye bags in younger and middle-aged faces.

How it differs from the external approach

The transcutaneous, or external, approach cuts through the skin just below the lashes and can remove skin, muscle and fat in one go, but it disturbs the lid’s front support and carries a higher risk of the lid pulling down or turning out; the transconjunctival approach works from behind, leaves no external scar, and has a lower malposition risk, at the cost of not removing skin. The two are different operations judged on different things¹.

That trade-off is the honest heart of the choice. Lower-lid work is judged less on how much is taken away than on whether the lid still sits correctly afterwards, and the inside approach is preferred partly because it spares the muscle and support at the front of the lid. The complication both approaches are weighed against is covered in lower eyelid malposition.

What it treats, and what it will not

It treats bulging fat, not loose skin: the transconjunctival route reaches the fat pads beautifully but has no way to take away a curtain of crepey lower-lid skin, so where skin is the main complaint a surgeon adds a small skin pinch, a laser or peel, or chooses the external approach instead. Matched to the right lid, it is precise; used on the wrong problem, it under-delivers³.

There is a second, increasingly common use. Rather than simply removing the fat, many surgeons now drape it down over the hollow at the rim to soften the shadow there, which reads as a smoother transition from lid to cheek than plain removal. That technique, and the tear-trough hollow it addresses, is set out in tear-trough and fat repositioning.

The procedure and recovery

It is usually done under local anaesthetic with sedation or a general anaesthetic, as a day case, and because the incision is inside the lid there is generally no external stitch to remove; bruising and swelling peak at 2 to 3 days and settle over roughly 1 to 2 weeks, with most people presentable at 7 to 14 days. Eye makeup and contact lenses wait about 2 weeks, and strenuous exercise about 2 to 3 weeks⁴.

Mine looked worse before it looked better, and the dry, gritty first few days were stranger than I had pictured, even without a visible wound to nurse. The eyes you see at one week are still swollen and still settling; the final smoothness took weeks to arrive. Why the eyes feel dry, and how long it tends to last, is covered in dry eyes after blepharoplasty.

The risks worth naming

The lower malposition risk is reduced but not abolished, dry or gritty eyes are the commonest after-effect and usually temporary, over-removal of fat can leave a hollow or sunken look, and the rare, sight-threatening emergency of a bleed behind the eye applies to any lower-lid surgery. Retrobulbar (orbital) haemorrhage is reported at roughly 1 in 2,000 to 1 in 25,000 and needs immediate treatment¹.

The eye is not a place to be casual about any of this, and “scarless” is a description of the skin, not a promise about the outcome. Over-resection is the quieter risk with this route, because it is easy to think more fat removed is better when a soft, natural contour usually means leaving some behind. The full account of what can go wrong, and how uncommon each is, sits in the pillar on blepharoplasty.
