Ptosis Correction (Eye-Opening Surgery) in Seoul

What is ptosis correction?

Ptosis correction is surgery to raise an upper eyelid that sits lower than it should. In medical terms, blepharoptosis describes an upper lid margin that covers more of the colored iris than usual, typically because the eye-opening mechanism is not working at full strength. In Korea the procedure is widely known as "eye-opening surgery" ( nun-maegyo ), because its purpose is to change how open the eye looks, not only the shape of the fold.

The eyelid is raised mainly by the levator palpebrae superioris, a muscle that runs back into the eye socket. At the front, it becomes a thin sheet called the levator aponeurosis, which attaches to the tarsal plate, the firm structure along the lid margin. A smaller muscle, Müller's muscle, adds a few millimeters of lift. If the levator is weak from birth, or if its aponeurosis has stretched or partially detached over time, the lid rests lower.

The effect is often subtle but meaningful. People with ptosis may raise their brows unconsciously to see, which can create forehead lines, and they may look drowsy in photographs. Correcting the lid can restore a brighter, more balanced gaze.

Why mild ptosis is often overlooked

Mild ptosis rarely announces itself. The body compensates quietly: the frontalis muscle in the forehead lifts the brows a little, the chin tilts up slightly, and the eye looks almost normal in the mirror. Over years, these small compensations show up as horizontal forehead lines, a heavy feeling around the eyes by evening, or a sense that photographs capture you looking sleepy.

Ptosis can also hide behind a double eyelid. If a fold is created over a lid that does not lift well, the crease may look thick, sausage-like or uneven, and the eye may still appear tired. This is one reason Dr. Kim measures eye-opening strength at every eyelid consultation, even when a patient has come only to ask about a fold. Knowing whether the levator is doing its job changes which operation makes sense, and helps avoid a result that needs revision later.

Ptosis is not only cosmetic. When the lid covers the pupil, it can narrow the upper field of vision. If that applies to you, mention it at consultation.

Who is a good candidate?

• Upper lids that cover part of the pupil or much of the upper iris
• Eyes that look sleepy, heavy or tired despite adequate rest
• Asymmetry where one eye opens less than the other
• Habitual brow raising to open the eyes, with forehead lines as a result
• A double eyelid fold that looks thick or sagging because the lid underneath does not lift well
• Stretching of the levator from long-term contact lens use or ageing

It may not be suitable, or needs special evaluation, if the drooping comes from a nerve or muscle disorder, if there is significant dry eye, or if the lid appears low mainly because excess skin or a low brow is covering it (sometimes called pseudoptosis). In those cases, other procedures such as upper blepharoplasty may be more appropriate. A careful examination tells these situations apart.

How Dr. Kim assesses and designs eye opening

Ptosis correction is a precise procedure. Changes of a single millimeter in lid height are noticeable, and the two sides need to be balanced against each other. At Will Be, Dr. Kim Jun-young personally performs each step, from the first measurements to the final follow-up.

The assessment includes the margin–reflex distance (MRD1), which is the distance between the light reflection on your cornea and the upper lid margin; levator function, which measures how far the lid travels from looking down to looking up; brow position and how much you use your forehead to open your eyes; fold height and skin quantity; and tear film and eye closure. Photographs from different angles help plan symmetry.

The design aims for an opening that suits your face, not the widest possible eye. An overly open eye can look startled and can dry the surface of the eye. The goal is a gaze that looks rested and natural: you, looking awake.

How is ptosis corrected?

The method depends on levator function and the degree of ptosis. Mild cases with good muscle function may suit a non-incisional technique that tightens the internal structures through tiny openings. Moderate cases are commonly treated through an incision along the crease. A typical incisional approach looks like this:

1. Design and marking with you sitting upright, including fold height and the planned lid position.
2. Local anesthesia, placed carefully so the muscle can still move, because your cooperation during surgery helps set the height.
3. Incision along the crease, with conservative trimming of skin and muscle when needed.
4. Exposing the levator aponeurosis by opening the orbital septum, the thin membrane that holds eyelid fat behind it.
5. Advancement or plication. The aponeurosis is reattached or folded onto the tarsal plate to shorten it, which increases lift.
6. Intraoperative checking. You are asked to open your eyes, and lid height, curvature and symmetry are adjusted in small increments.
7. Fold creation and closure. The double eyelid crease is formed and the skin closed with fine sutures.

When levator function is very weak, other techniques may use a neighboring support, such as the conjoint fascial sheath, to help lift the lid. Your surgeon will explain which approach suits your anatomy.

Anesthesia and surgery time

Surgery typically takes about one to one and a half hours for both eyes, depending on the technique and whether other procedures are combined. It is performed under local anesthesia, often with light IV sedation that still allows you to open your eyes on request. You go home the same day. See anesthesia options explained.

Risks and how they are minimised

Possible risks include under-correction (the lid remains lower than planned), over-correction (the eye looks too wide or startled), asymmetry, an uneven lid contour, dry eye or irritation, temporary difficulty closing the eye fully (lagophthalmos), bruising, infection, and visible scarring. A small number of patients need a later adjustment. Individual results vary.

These risks are reduced by precise measurement before surgery, conservative adjustment, checking lid height with your cooperation during the operation, and regular follow-up. Protective eye ointment and lubricating drops are used while the eye adapts. Read more in eyelid surgery risks.

Combining with other procedures

Ptosis correction is very often combined with incisional double eyelid surgery, since both are done through the same incision. It is also frequently part of revision surgery, because an unnoticed weak levator is a common reason a previous fold looks heavy. It can be paired with epicanthoplasty when the inner corner is covered. For the differences between the two main eyelid operations, see ptosis correction vs double eyelid surgery.

Preparing for surgery and caring for your eyes

Before surgery, your surgeon may ask you to pause aspirin, some anti-inflammatory medicines and supplements such as fish oil and vitamin E; do not stop prescribed medicine without advice from your own doctor. Stop wearing contact lenses for the days specified, and avoid smoking and alcohol.

Afterwards, keep your head raised, use cold compresses in the first 48 hours, and apply lubricating drops and ointment as directed, especially at night. Avoid rubbing your eyes, heavy exercise, saunas and swimming for about two weeks. Screen time is fine in moderation, but take breaks, because concentrating reduces blinking and can make eyes feel dry.

Staying in Korea as an international patient

Plan about 7–10 days in Seoul. A typical schedule is consultation on arrival, surgery the next day, a check within a few days, suture removal around day 5–7, and a final review before you fly. Because small lid-height differences are easier to address early, staying the full period is helpful. Once home, you can share photos at agreed intervals so Dr. Kim can continue to review your healing.
