Asian eyelid surgery, also called Asian blepharoplasty or “double eyelid surgery,” is a cosmetic procedure that creates a visible crease in the upper eyelid. About half of people of East Asian descent are born without this crease, a feature sometimes called a monolid. The surgery is one of the most commonly performed cosmetic procedures in East Asia and among the most requested by Asian patients worldwide.
Why Some Eyelids Have a Crease and Others Don’t
Whether your upper eyelid has a visible fold comes down to what’s happening beneath the skin. In eyelids with a crease, the muscle that lifts the eyelid sends small fibers forward that attach to the skin. When the eye opens, that attachment pulls the skin inward, creating a fold. In a monolid, those fibers either don’t reach the skin or are blocked by a thicker layer of soft tissue, fat, and muscle sitting between the lifting muscle and the outer skin. The eyelid still opens normally, but no fold forms.
Asian eyelids also tend to have more fat in front of the lifting muscle and a fuller layer of the circular muscle that helps you blink. This extra tissue is one reason monolids appear smoother and sometimes puffier. The surgery addresses these structural differences directly.
What the Surgery Actually Does
The core goal is straightforward: create a connection between the skin and the deeper eyelid structures so that a crease forms when the eye opens. Surgeons accomplish this using one of two broad approaches.
Non-Incisional (Suture) Technique
This method uses tiny puncture holes rather than a full cut across the eyelid. Through several small openings, the surgeon threads a fine suture that loops between the outer skin and the tissue along the upper edge of the firm cartilage-like plate inside your eyelid. When tied with the right tension, this buried stitch pulls the skin inward each time you open your eye, mimicking a natural crease. Some surgeons also remove small amounts of fat or muscle through these punctures to help the fold hold its shape long-term.
The suture technique is faster, causes less swelling, and leaves minimal scarring. Long-term data from surgeons tracking patients over 12 to 15 years shows durable results, with revision rates around 1 to 2 percent for loosening of the fold on one side. That said, it works best on thinner eyelids with less tissue bulk. If you have a very full or heavy eyelid, the fold created by sutures alone may gradually soften or disappear.
Incisional Technique
This approach involves a full incision along the planned crease line. Through that opening, the surgeon can remove excess skin, trim the muscle layer, and reduce orbital fat before stitching the skin to the underlying lifting muscle or cartilage plate. Because the surgeon has direct access to every tissue layer, the incisional method allows more precise reshaping and produces a permanent crease through scar adhesion.
The tradeoff is a longer recovery and a fine scar that sits in the crease itself, which typically becomes nearly invisible once healed. Incisional surgery is generally recommended for people with thicker eyelid skin, significant puffiness, or those who want a more defined fold.
Crease Styles and Customization
Not everyone wants the same look. Surgeons typically discuss three crease shapes before the procedure. A “parallel” crease runs evenly above the lash line from the inner to outer corner, creating a wider, more open appearance. A “tapered” crease starts narrow near the inner corner and widens toward the outer corner, which is the most common natural crease shape in Asian eyelids. A low crease sits closer to the lashes and produces a subtler result. The height of the crease is measured from the lash line, usually between 6.5 and 8.5 millimeters at the center of the eyelid, and adjusted based on the anatomy of your specific eyelid.
Epicanthoplasty: A Common Add-On
Many Asian eyelids also have an epicanthal fold, a small web of skin that covers the inner corner of the eye. A prominent epicanthal fold can make the eyes appear closer together or give a flatter look to the inner eyelid area. Epicanthoplasty is a separate but frequently combined procedure that opens up this inner corner. Surgeons use small flap rearrangements (techniques with names like Z-plasty or skin redraping) to release the tight skin without leaving noticeable scars. It’s not required for double eyelid surgery but is often discussed during the same consultation.
What to Expect During the Procedure
Asian eyelid surgery is performed under local anesthesia, sometimes with light sedation. You’re awake but won’t feel pain in the eyelid area. The surgeon may ask you to open your eyes during the procedure to check crease symmetry in real time. An upper eyelid procedure typically takes about 45 minutes to one hour. The suture-only technique is often shorter. You go home the same day.
Recovery Timeline
Swelling and bruising are most noticeable in the first week. Your eyelids will look puffy and possibly discolored, and your vision may feel slightly blurry from the swelling pressing on your eyes. If removable stitches were placed, they come out between 5 and 10 days after surgery.
Most of the visible swelling and bruising resolves within one to three weeks. At that point, you’ll start to see the shape of your new crease, though it will still look somewhat swollen compared to the final result. The crease continues to settle and refine for one to three months as deeper swelling fades and the tissues fully heal. During the first few weeks, cold compresses and keeping your head elevated while sleeping help reduce puffiness.
Risks and Possible Complications
The most common issue is asymmetry, where one crease heals slightly higher, deeper, or differently shaped than the other. Minor asymmetry is normal in all faces, but noticeable differences sometimes require a touch-up procedure. With the suture technique specifically, the main risks include suture loosening (causing the fold to partially or fully disappear), the stitch becoming palpable under the skin, or incomplete crease formation. Some patients report a feeling of tightness or strain in the eyelid that usually fades within a few weeks.
With incisional surgery, an overly aggressive crease height can lead to a stiff or unnatural fold, and in rare cases, damage to the muscle that lifts the eyelid can cause a slight droop called secondary ptosis. Setting the crease too high also sometimes triggers a compensatory brow-raise that can look unnatural.
Pre-existing dry eyes or a compromised blink reflex increase the risk of postoperative dryness and irritation, since even minor changes to eyelid tension can affect how completely you close your eyes. Blood-thinning medications, including common supplements like fish oil, vitamin E, and ginkgo biloba, raise the risk of bleeding and should be stopped before surgery per your surgeon’s instructions.
Who Is a Good Candidate
Most healthy adults who want a visible eyelid crease are candidates. The best results come when expectations are realistic and specific. Bringing reference photos and discussing exactly what crease height and shape you’re after helps the surgeon plan accurately. People with thinner eyelids and less orbital fat tend to get good results from the suture technique, while those with heavier, puffier lids are usually better suited to the incisional approach.
Surgeons screen for conditions that make the procedure inadvisable. Severe dry eye disease, an already weakened blink, and unrealistic expectations are all red flags. Screening also aims to identify body dysmorphic disorder, where someone fixates on perceived flaws that others don’t notice, since surgery rarely resolves the underlying distress in these cases.
