Ptosis — drooping of the upper eyelid — is treated as both a functional and aesthetic concern in Korean ophthalmic plastic surgery. Roughly 40% of Korean double eyelid surgeries include ptosis correction, a much higher rate than Western markets where ptosis surgery is treated as a separate medical procedure. Understanding the technique distinction matters for patients planning surgery.
What ptosis is
- Drooping of the upper eyelid covering more of the iris than normal.
- Causes "sleepy eye" or "tired-looking" appearance.
- Often asymmetric.
- May affect vision in severe cases.
- Caused by weakness of the levator palpebrae superioris muscle or its tendon.
Severity grading
- Mild — 1–2mm of additional droop; cosmetically noticeable.
- Moderate — 3mm of droop; may affect peripheral vision.
- Severe — 4mm+ of droop; functional vision impact.
- Severity guides technique selection.
The two main techniques
Non-incisional ptosis correction
- No external incision.
- Sutures placed through eyelid to engage levator muscle.
- Creates a double fold while lifting eyelid.
- Suitable for mild-to-moderate ptosis.
- Faster recovery.
- Reversible if needed.
- Limitations — won\'t address severe ptosis; sutures may loosen over years.
Incisional (open) ptosis correction
- Standard incision along eyelid crease.
- Direct visualization of levator aponeurosis.
- Levator tendon shortened or advanced.
- Combined with double eyelid surgery typically.
- Suitable for moderate-to-severe ptosis.
- More predictable long-term result.
- Slightly longer recovery.
Müller\'s muscle conjunctival resection (MMCR)
- Posterior approach (no external incision).
- Conjunctival side; precise muscle resection.
- Good for mild ptosis with positive phenylephrine test.
- Less swelling.
Frontalis sling
- For severe ptosis with poor levator function.
- Connects eyelid to forehead muscle (frontalis).
- Patient lifts eyebrow to open eye.
- Reserved for cases with weak levator function.
How Korean surgeons decide
Levator function measurement
- Patient looks down then up, with brow stabilized.
- Eyelid excursion measured in millimeters.
- Good function (10mm+): standard techniques work well.
- Poor function (<5mm): frontalis sling considered.
Phenylephrine test
- Drop of phenylephrine in eye.
- Stimulates Müller\'s muscle.
- Positive response (eyelid lifts) suggests MMCR will work.
Symmetry assessment
- Compare both eyelids.
- Asymmetric correction common.
- Stronger correction on side with more ptosis.
Combination with double eyelid surgery
- Most Korean ptosis patients combine with double eyelid surgery.
- Same incision used.
- Single surgery, single recovery.
- Aesthetic and functional improvement.
- Result: bigger, more open eyes.
Recovery timeline
Non-incisional
- Sutures self-dissolving or removed at day 5–7.
- Visible swelling 1–2 weeks.
- Return to social activities at 1–2 weeks.
- Final shape settles 2–3 months.
Incisional
- Sutures removed at day 5–7.
- Visible swelling 2–3 weeks.
- Bruising 1–3 weeks.
- Return to social activities at 2–3 weeks.
- Final shape settles 3–6 months.
Costs in Korean clinics 2026
- Non-incisional ptosis correction: ₩1,500,000–₩3,000,000.
- Incisional ptosis correction: ₩2,500,000–₩5,000,000.
- Combined with double eyelid surgery: ₩3,500,000–₩7,000,000.
- Revision pricing typically 30–50% higher.
Risks specific to ptosis surgery
- Undercorrection — most common revision reason; addressed at 6 months.
- Overcorrection — eye opens too wide; rare with conservative technique.
- Asymmetry — possible; revision considered.
- Lagophthalmos — incomplete eye closure; usually temporary.
- Dry eye — common temporarily; usually resolves.
- Loss of lift over years — possible recurrence.
Why Korea performs ptosis correction frequently
- Cultural recognition of "sleepy eye" as concern.
- Combined approach with double eyelid surgery efficient.
- Ophthalmic plastic surgery training widespread.
- Patient demand for big, alert eyes.
- Modest additional cost with substantial visual improvement.
Who is and isn\'t a candidate
Good candidates
- Visible eyelid droop affecting appearance or vision.
- Stable preference for change.
- Healthy and able to follow recovery protocol.
- Realistic expectations.
- Good levator function for incisional approach.
Less ideal candidates
- Active eye disease.
- Severe dry eye predating surgery.
- BDD pattern with multiple unsatisfying revisions.
- Unrealistic expectations about exact symmetry.
What patients should know
- Ptosis correction is a precision procedure with high revision rate compared to other eyelid surgeries.
- Surgeon experience matters significantly.
- Initial result settles over months.
- Touch-up at 6 months sometimes needed.
- Long-term follow-up beneficial.
The honest framing
Ptosis correction is one of the more technically demanding eyelid procedures — small differences in technique produce different outcomes, and asymmetric starting anatomy makes perfect symmetry difficult. Korean ophthalmic plastic surgery has extensive experience with both incisional and non-incisional approaches, and the surgeons who get good outcomes are those who match technique to severity rather than offering one-size-fits-all. The patients who get good outcomes accept that some asymmetry may persist, allow time for swelling to resolve before judging results, and understand that revision rate is higher than for some cosmetic procedures. Match the technique to the severity, choose surgeons with demonstrated ptosis-specific experience, and allow proper healing time before judging.
