Two techniques remove or reposition the fat that causes under-eye bags, but they reach that fat through different routes, and that difference is what protects the natural shape of the eye. Transconjunctival surgery works through a hidden incision inside the eyelid, leaving the outer skin untouched. Transcutaneous surgery works through an incision just below the lash line, which allows a surgeon to address loose skin at the same time but also disturbs more of the eyelid's supporting structure. For patients whose main concern is puffiness rather than sagging skin, this difference often decides which technique keeps the eye looking like itself.
Dr. Matthew D. Brace, MSc, MD, FRCS(C), a double-board-certified facial plastic surgeon, performs lower eyelid surgery routinely at his Guelph practice and takes a conservative, staged approach to preserve the eye's natural contour. In this blog, Dr. Brace walks through how each technique works, who tends to suit each one, and why choosing the right one matters as much as the surgery itself.
What Transconjunctival Surgery Treats
Transconjunctival lower blepharoplasty targets fat, often called "eye bags," below the eye. Because the incision is made inside the eyelid, there is no visible scar and the skin is left untouched. Excess fat can be removed, or repositioned into hollow areas below the eye to smooth the transition between lid and cheek. When skin laxity is also present, this approach is often paired with a secondary treatment such as laser resurfacing, a chemical peel, or a skin pinch procedure.
Good candidates for this approach generally have:
- Prominent fat pockets or puffiness with minimal excess skin
- Healthy eyelid muscle tone and well-supported lower lids
- A preference for an incision with no visible scarring
What Transcutaneous Surgery Treats
Transcutaneous lower blepharoplasty addresses skin, muscle, and fat together. It reshapes the lower eyelid and smooths the separation between lid and cheek, making it a better option for patients with loose or crepey skin in addition to fat or hollowing. The tradeoff is a longer, more involved recovery. Swelling and bruising tend to be more pronounced, and the procedure typically takes one to two hours with anti-inflammatory injections, antibiotics, and pain medication as part of aftercare.
Why the Approach You Choose Affects Your Eye Shape
Rounded or pulled down lower eyelids after surgery usually trace back to how much the skin and underlying tissue were disturbed during the original procedure. A case series indexed by the National Library of Medicine found a lower rate of eyelid retraction with the transconjunctival approach, likely because it leaves the skin and underlying muscle undisturbed. Every lower eyelid ages differently, however, and patients with significant skin excess are often better served by transcutaneous surgery despite the longer recovery. That's why Dr. Brace evaluates eyelid tone, eye position, and tendon support at the consultation and often stages procedures rather than combining them into a single operation.
Dr. Matthew D. Brace, FRCS(C): Natural Looking Eyelid Rejuvenation in Guelph
Choosing between transconjunctival and transcutaneous lower blepharoplasty comes down to anatomy. Getting that choice right is what keeps the eyes looking rested. Dr. Brace's fellowship training in facial plastic and reconstructive surgery, paired with his measured, individualized approach to eyelid surgery, helps Guelph-area patients get a technique matched to their own eyes rather than a one-size-fits-all plan. Patients ready to find out which approach fits them can schedule a consultation with Dr. Brace.
