The term "Sanpaku gan" (三白眼), or simply "Sanpaku", is a Japanese phrase meaning "three whites." In English, it refers to an eye appearance where the white part of the eye, the sclera, is visible between the iris and either the lower or upper eyelid. The focus here is on the white visible below the iris, known as "Yin Sanpaku."

Common Pseudonyms and Cultural Beliefs

There are two main types of Sanpaku eyes:

• Yin Sanpaku: White sclera visible beneath the iris
• Yang Sanpaku: White sclera visible above the iris

Historically, these eye traits have been linked to physical and spiritual imbalances. Superstitions suggest that people with Yin Sanpaku face tragic fates, illness, or early death, with famous examples like Princess Diana, John F. Kennedy, Abraham Lincoln, and Marilyn Monroe often cited. Yang Sanpaku, on the other hand, is associated with violent tendencies, with cult leader Charles Manson as a notorious example.

These beliefs gained popularity in the West during the 1960s, largely due to George Ohsawa’s book You Are All Sanpaku, which used the concept to promote the macrobiotic diet. Importantly, there is no scientific evidence supporting these superstitions. The tragic outcomes linked to Sanpaku eyes are coincidental, and the so-called "curse" holds no real power beyond personal belief.

Medical Perspective: Distinguishing Appearance from Underlying Conditions

While "sanpaku eyes" is steeped in cultural meaning, the visible white below the iris is a real anatomical feature. Medically, this is called scleral show or may indicate eyelid retraction. Unlike the mystical interpretations, this is an anatomical variation or symptom of an underlying condition.

Eyelid retraction occurs when the eyelid is abnormally positioned—either raised or lowered—exposing the sclera between the eyelid margin and cornea. Causes include congenital issues, thyroid eye disease, trauma, prior surgeries, or aging.

Beyond appearance, untreated eyelid retraction can cause discomfort and functional problems such as incomplete eye closure, dry eyes, redness, burning, irritation, tearing, and in severe cases, corneal ulcers. Surgical correction not only improves cosmetic concerns but also helps prevent these complications by restoring proper eyelid position.

Medical Solutions for Eye Reshaping: Canthoplasty Procedures

For those concerned about the appearance of Sanpaku eyes or eyelid function, canthoplasty procedures offer effective surgical solutions. These surgeries reshape the eye, reduce visible scleral show, and create a more balanced, aesthetically pleasing eye contour.

Canthoplasty: Traditional Surgical Approach

Canthoplasty is a reconstructive cosmetic surgery that reshapes the canthus, the corner where the upper and lower eyelids meet. It tightens muscles, tendons, ligaments, and connective tissues to correct droopy or sagging eyelids, unevenness, and eye shape. Also called inferior retinacular suspension or the almond eye procedure, it can create a refined, almond-shaped eye.

This surgery addresses cosmetic concerns like visible white below the iris and medically treats eyelid dysfunctions such as corneal damage (keratopathy), ectropion, entropion, lagophthalmos, or trauma.

Key types of canthoplasty include:

• Lateral Canthoplasty: Focuses on the outer eye corner, lifting and tightening the lateral canthus to elongate the eye and reduce scleral show below the iris.
• Hotz Canthoplasty (Lower Canthoplasty / Bottom Opening): Popular in Korea, this increases vertical width at the outer eye corner and aligns the pupil with the lower eyelid using "fascial fixation" to soft tissue, producing a natural look without awkwardness.
• Epicanthoplasty: Targets the inner canthus and epicanthic fold, often combined with other surgeries to enhance eye openness, especially in Asian patients.

Related procedures:

• Canthopexy: A less invasive tightening of the canthal tendon without detachment, suitable for mild cases.
• Blepharoplasty: Removes excess skin, muscle, and fat from eyelids, often combined with canthoplasty for full rejuvenation.

The Surgical Process: Step-by-Step

1. Pre-operative Preparation: Includes lab tests, medication adjustments, quitting smoking, and switching to glasses from contacts.
2. Anesthesia: General anesthesia (sleep) or local anesthesia (numbing), sometimes with sedation.
3. Incision: Small incisions near the eyelid, often 5-7 mm lateral to the eye corner, minimizing visible scars.
4. Tissue Adjustment: Tightening and repositioning the eyelid tendon and muscles. Traditional canthoplasty detaches and shortens the lateral canthal tendon, reattaching it to the orbital rim. Hotz canthoplasty fixes tissue to soft tissue (capsulopalpebral fascia).
5. Suturing: Fine stitches close the incision.
6. Duration: Typically 30 minutes to 3 hours, depending on complexity.

Recovery and Potential Considerations

Post-surgery, patients usually feel no pain due to anesthesia but may experience mild discomfort, swelling, and bruising for 1-2 weeks. Swelling peaks around 48 hours and then subsides. Protective eye pads are worn for 24-48 hours. Stitches are removed around day 5-7. Makeup and light activities can resume after 7-10 days, but rubbing eyes, heavy exercise, and sun exposure should be avoided initially.

Wound care involves cleaning with sterile water and applying antibiotic ointment three times daily for two weeks. Keeping the head elevated helps reduce swelling. Full recovery takes 2-4 weeks, with final results visible after 2-3 months as residual swelling fades.

Risks include bleeding, infection, overcorrection, undercorrection, and very rarely, eye or vision damage. Choosing an experienced surgeon is crucial to minimize complications and achieve natural results.

Laser Canthoplasty: Precision and Innovation

Laser Canthoplasty is a modern advancement using laser technology to reshape the eye corners with high precision. Popular in Korea, it helps achieve youthful, open, almond-shaped eyes.

Advantages over traditional surgery include:

• Precision: Laser creates exact incisions at precise angles and depths.
• Reduced Bleeding and Inflammation: Laser cauterizes while cutting, minimizing tissue damage.
• Minimal Scarring: Laser incisions heal with less visible marks.
• Quicker Healing: Less trauma leads to faster recovery.

The Laser Surgical Process: Step-by-Step

1. Anesthesia: Usually local anesthesia in an outpatient setting.
2. Laser Incisions: Precise cuts made at the lateral canthus with a laser device.
3. Reshaping: Adjusting the lateral canthal tendon to achieve desired eye shape without extensive tissue removal.
4. Suturing: Fine stitches close the incisions.
5. Duration: Typically 30 minutes to 1 hour, up to 2 hours for complex cases.

Recovery and Benefits

Post-op care includes cold compresses and following surgeon instructions. Recovery is faster than traditional surgery, with most patients resuming normal activities within a week. Laser Canthoplasty offers less bleeding, swelling, scarring, and a more comfortable healing process.

Patient Experiences and Outcomes: Addressing "Sanpaku Eyes"

Canthoplasty directly targets the visible white sclera below the iris, offering both aesthetic and psychological benefits.

How Canthoplasty Addresses the "Sanpaku" Appearance

Procedures like Lateral Canthoplasty and Hotz Canthoplasty adjust the lower eyelid and outer eye corner to reduce scleral show, creating balanced, natural-looking eyes. Surgeons carefully evaluate scleral exposure, eyelid crease, and pupil size to ensure harmony with facial features.

Techniques such as "fascial fixation" in Hotz Canthoplasty and "periosteum fixation" in Lateral Canthoplasty help achieve strong, natural openings without exposing mucous membranes or causing eyelash problems. The goal is a subtle, undetectable enhancement that avoids an unnatural look.

Reported Patient Outcomes and Benefits

Patients often report eyes that look bigger, clearer, and more refreshed, with a more elongated almond shape. Combining Hotz and Lateral Canthoplasty (Dual Canthoplasty) maximizes eye opening and facial balance.

Minimal swelling and scarring contribute to natural results, with many patients returning to daily life quickly, sometimes the next day. Psychological benefits include boosted self-confidence, feeling refreshed, and improved self-esteem. Many patients feel comfortable without makeup and report a significant positive impact on their quality of life.

Important Considerations for Patients

Realistic expectations and understanding recovery timelines are essential. Choosing an experienced surgeon with a strong track record in eye contour surgery is critical to ensure safety, effectiveness, and natural results, minimizing risks like overcorrection or unnatural appearance.

Conclusion

While "sanpaku eyes" stem from superstition, the visible white below the iris is a real anatomical concern that can be effectively treated. Canthoplasty and Laser Canthoplasty offer precise surgical solutions to reduce scleral show, improve eye aesthetics, and relieve discomfort like dry eyes. South Korea leads globally in these procedures, combining expert surgeons, advanced technology, competitive pricing, and excellent patient care. Patients often experience not only enhanced eye appearance but also significant boosts in confidence and well-being. Choosing a qualified surgeon and making informed decisions are key to achieving safe, natural, and satisfying results.
