Understanding Double Eyelid Surgery

Understanding Double Eyelid Surgery: What Patients Should Know Before Choosing a Surgeon in Busan

Double eyelid surgery, also known as blepharoplasty for eyelid crease formation, is one of the most commonly requested procedures in Korean aesthetic surgery. For many patients, monolids or naturally low, undefined eyelid creases can make the eyes appear smaller, tired, or asymmetrical, even when there is nothing medically wrong with eye function. Double eyelid surgery addresses this by creating a defined upper eyelid fold, opening up the eye area and giving a more alert, balanced appearance. At IBON Plastic Surgery in Busanjin-gu, Busan, this procedure is performed under the direct care of Dr. Kim Ju-Chan, a board-certified plastic surgeon whose practice is built around eye and upper-face surgery specifically, rather than the broader catalogue of procedures found at larger, multi-surgeon centers.

What Causes a Monolid or Undefined Eyelid Crease

The presence or absence of a double eyelid crease is primarily anatomical. It depends on how the levator muscle — the muscle responsible for lifting the upper eyelid — connects to the skin above it. When this muscle's fibers extend through the orbital septum and attach firmly to the overlying skin, a natural crease forms as the eye opens. In some people, this connection is shallow, incomplete, or absent, resulting in a single, uncreased eyelid (a monolid). Others may have a partial or asymmetrical crease that fades throughout the day due to fat distribution, skin thickness, or age-related laxity.

None of this reflects poor eye health; it is simply a variation in eyelid anatomy that is common across East Asian populations and is not itself a medical condition. Many patients choose to modify it for cosmetic reasons, often citing a desire for eyes that look more open, symmetrical, or expressive in photographs and daily life. In some cases, what looks like a purely cosmetic concern is actually connected to a functional issue — most notably ptosis, where a weakened or stretched levator muscle causes the eyelid to droop and can mildly restrict the visual field. Distinguishing between a cosmetic monolid and a functional ptosis is one of the first things an experienced eye surgeon evaluates, since the surgical approach for each differs.

How Double Eyelid Surgery Works

There are two general surgical approaches, and the right one depends on individual anatomy rather than personal preference alone.

Non-incisional (buried suture) method. Small sutures are placed through tiny openings in the eyelid to create an adhesion between the skin and the underlying levator muscle, forming a natural-looking crease without a visible external incision. This approach suits patients with thinner eyelid skin, minimal excess fat, and good skin elasticity, and it typically involves less initial swelling and a shorter visible recovery period. Because no skin or fat is removed, the technique also preserves more flexibility for future adjustment if a patient's preferences change over time.

Incisional method. A full incision is made along the intended crease line, allowing the surgeon to remove excess skin, fat, or muscle as needed before forming the fold. This method is generally recommended for patients with thicker eyelid skin, more pronounced fat pads, existing skin laxity, or previous surgery that needs to be revised. Because tissue is directly addressed and the fold is reinforced with a surgical scar line along the crease, results tend to be more durable, though healing takes longer and initial swelling is typically more pronounced.

Revision double eyelid surgery. Not every double eyelid procedure is a first-time surgery. Some patients arrive after a previous operation — performed at another clinic — that has faded, become asymmetrical, lost its shape, or simply did not match what was originally discussed. Revision cases are technically more demanding, since they involve working with scar tissue, altered fat distribution, and eyelid structures that no longer match their original anatomy. At IBON, both first-time and revision double eyelid surgery are part of the clinic's core scope, reflecting the level of experience required to manage cases that did not go as planned elsewhere.

Who Is a Suitable Candidate

Good candidates for double eyelid surgery are generally in good general health, have realistic expectations about what the procedure can achieve, and are seeking a natural-looking, proportionate result rather than a dramatic change. Suitability also depends on several anatomical factors assessed during consultation:

• Eyelid skin thickness and elasticity
• Amount and distribution of orbital fat, including whether under-eye or upper eyelid fat repositioning may be needed alongside crease formation
• Existing brow position, since a low or heavy brow can affect how an eyelid crease appears once formed
• Whether ptosis is present, which may require a different or combined surgical approach addressing the levator muscle itself rather than the skin alone
• Age-related changes, since eyelid surgery needs differ between younger patients seeking their first procedure and older patients dealing with skin laxity or drooping that has developed over time

Because these factors vary significantly from person to person, an in-person or detailed consultation is necessary before any surgical plan is finalized. Patients considering revision surgery, in particular, benefit from a careful anatomical assessment of what changed since the original procedure, including how much scar tissue has formed and whether the original crease height is still achievable.

The Procedure Process at IBON

Every consultation and every operation at IBON is conducted personally by Dr. Kim Ju-Chan, without handoff to another surgeon — a structure sometimes referred to in Korea as a single-director system. IBON does not permit substitute or proxy surgery, meaning the surgeon a patient meets during consultation is the same surgeon who performs the operation and reviews recovery afterward. The process generally follows these stages:

1. Consultation and assessment. Dr. Kim examines eyelid skin quality, muscle function, fat distribution, and brow position, and discusses the patient's goals in relation to what their anatomy can realistically support. For patients considering revision surgery, this stage also involves reviewing what was done previously and what can be adjusted.
2. Surgical planning. Based on this assessment, the non-incisional or incisional method is selected, along with any additional adjustments such as fat repositioning, epicanthoplasty (inner corner adjustment), or lateral canthoplasty (outer corner adjustment) if the patient's goals extend beyond crease formation alone.
3. The procedure itself. Eyelid surgery is typically performed under local anesthesia, often with light sedation, and usually takes under two hours depending on complexity and whether additional procedures are combined.
4. Immediate post-operative care. Patients are monitored before discharge, with instructions on swelling management, cold compress use, and wound care specific to the technique used.
5. Structured follow-up. IBON treats aftercare as part of the procedure rather than an optional add-on, with scheduled review visits during the healing period to check crease symmetry, wound healing, and overall recovery progress.

The Surgeon's Background and Approach

Dr. Kim Ju-Chan completed his plastic surgery training at Dong-A University Hospital, one of Busan's major teaching hospitals, and previously held director positions at several plastic surgery clinics — including Zenith Plastic Surgery, Haneul Plastic Surgery, and The Goun Plastic Surgery — before founding IBON. He is a full member of several Korean academic surgical societies, including the Korean Society of Plastic and Reconstructive Surgeons, the Korean Society for Aesthetic Plastic Surgery, the Korean Cleft Palate and Craniofacial Association, and the Korean Association of Aesthetic Plastic Surgeons in Private Practice. He has also contributed research to domestic and international academic journals over the course of his career, reflecting an ongoing engagement with the evidence base behind the procedures he performs, and has written public-facing columns addressing common misconceptions around eye surgery safety and recovery.

IBON's stated patient commitments include no proxy surgery, no unnecessary treatment, genuine and appropriately dosed materials for any adjunct procedures, and realistic goal-setting without exaggerated promises. This approach is particularly relevant to a procedure like double eyelid surgery, where subtlety and facial proportion often matter more than dramatic transformation, and where overcorrection can look less natural than a modest, well-planned adjustment. The clinic also operates what it describes as a surgical responsibility guarantee, committing to continued care and accountability for outcomes after the operation is complete.

Recovery, Safety, and Realistic Outcomes

Recovery from double eyelid surgery varies by technique. Non-incisional procedures generally involve less initial swelling and a somewhat faster return to a natural appearance, often allowing patients to return to normal activities within a week, though strenuous exercise and eye makeup are typically restricted for longer. Incisional surgery typically requires a longer period — often one to two weeks — before bruising and swelling subside enough for the final crease shape to become apparent, and scar lines along the crease usually take several weeks to fade into the natural fold.

Full settling of the eyelid, including resolution of minor asymmetry or residual swelling, can continue for several weeks to a few months, and patients are generally advised not to judge the final result too early in the healing process. As with any surgical procedure, risks such as infection, temporary asymmetry, under- or over-correction, or an eyelid crease that does not fully match initial expectations exist, which is why careful pre-operative assessment and adherence to post-operative care instructions — including follow-up visits — are important parts of minimizing complications.

Results are best understood as an enhancement of existing anatomy rather than a uniform outcome applied to every patient. A surgeon's experience in reading eyelid structure — skin, muscle, and fat together, and how they interact with brow position and eye shape — has a direct bearing on how natural, symmetrical, and long-lasting the result will be, particularly in more complex or revision cases.

Planning a Visit From Abroad

IBON Plastic Surgery is registered under Korea's Medical Service Act as a medical institution authorized to treat international patients. Because eyelid surgery involves a defined healing and follow-up period, international patients are advised to contact the clinic in advance to coordinate consultation timing, language arrangements, and the post-operative visits their recovery will require before finalizing travel plans. Given that final results take time to settle, patients traveling from abroad should factor at least one follow-up visit into their itinerary rather than planning to leave immediately after surgery.
