LASEK
Overview
LASEK (Laser-Assisted Subepithelial Keratectomy) is a refractive surgery designed to correct myopia, hyperopia, and astigmatism. Unlike LASIK, which involves cutting a deep corneal flap, LASEK involves gently loosening and pushing aside only the outermost layer of the eye, called the epithelium. A specialized excimer laser then reshapes the underlying corneal tissue to improve how light focuses on the retina.
Because the procedure preserves more of the corneal structure, it is often recommended for patients who have thin or irregular corneas that might make them ineligible for traditional LASIK. It is also a preferred choice for individuals involved in contact sports or high-impact professions, as there is no risk of flap displacement later in life.
Expected Results
The primary goal of LASEK is to reduce or eliminate the dependence on glasses and contact lenses. The majority of patients achieve significant visual improvement, often reaching 20/20, though individual results vary based on the initial prescription and the eye's healing response. While the initial vision may be slightly blurry during the first few days, clarity typically improves steadily over several weeks.
It is important to note that while LASEK corrects existing refractive errors, it does not prevent age-related vision changes such as presbyopia. Most patients experience stable, long-term vision correction once the eyes have fully stabilized, which usually occurs within three to six months post-surgery.
Why Korea & Cost
South Korea is a global leader in ophthalmology, known for its high volume of refractive surgeries and early adoption of advanced laser technologies. Korean clinics often utilize the latest excimer laser systems that offer high levels of precision and integrated eye-tracking software to enhance safety. Surgeons in Seoul are highly experienced, frequently performing thousands of procedures annually, which contributes to refined techniques and efficient care.
The cost of LASEK in Korea is influenced by several factors, including the specific laser technology used (such as All-Laser LASEK), the surgeon's expertise, and the inclusion of comprehensive pre-operative testing and post-operative medications. A detailed consultation and eye examination are required to provide an exact quote tailored to the patient's specific ocular health.
Recovery & Aftercare
Recovery from LASEK is generally longer and more sensitive than LASIK because the epithelial layer needs time to regenerate. A protective "bandage" contact lens is placed over the eye immediately after surgery and is typically removed by a doctor after 3 to 5 days. During this initial period, patients may experience discomfort, light sensitivity, and a gritty sensation in the eyes.
Strict adherence to the prescribed eye drop regimen is crucial for preventing infection and managing inflammation. Patients are advised to rest their eyes, avoid bright sunlight by wearing UV-protective sunglasses, and refrain from rubbing their eyes or engaging in strenuous activities for the first week to ensure the new epithelial cells heal smoothly.
Who Is It For?
- Patients with thin or flat corneas unsuitable for LASIK
- Individuals with active lifestyles or high-impact hobbies
- Those with stable vision prescriptions for at least one year
- Patients with dry eye concerns who want to minimize nerve disruption
- Individuals looking for a flap-free vision correction method
Benefits
- Eliminates the risk of corneal flap complications
- Preserves more corneal thickness and structural integrity
- Suitable for patients with high myopia or thin corneas
- Lower risk of long-term post-operative dry eye
- Excellent long-term visual stability and clarity
How It's Done
- Application of numbing anesthetic eye drops
- Application of a diluted alcohol solution to loosen the epithelium
- Gently sliding the epithelial layer to the side
- Excimer laser reshaping of the corneal stroma
- Repositioning the epithelial layer over the treated area
- Placement of a protective bandage contact lens
Risks & Side Effects
- Temporary eye discomfort and light sensitivity
- Longer initial recovery period compared to LASIK
- Risk of corneal haze or temporary under-correction
- Potential for infection during the epithelial healing phase
- Temporary regression of vision during the first few months
Recovery
- Bandage contact lens remains in place for 3 to 5 days
- Initial blurred vision and sensitivity for the first 72 hours
- Epithelial layer typically heals within one week
- Vision stabilizes gradually over 1 to 3 months
- Regular follow-up appointments to monitor healing progress
Aftercare
- Use prescribed antibiotic and anti-inflammatory drops as directed
- Wear UV-protective sunglasses when outdoors for several weeks
- Avoid getting water or soap in the eyes for the first week
- Refrain from eye makeup for at least two weeks
- Avoid swimming and saunas for one month post-procedure
Precautions
- Do not rub or touch the eyes under any circumstances
- Avoid dusty or smoky environments during early recovery
- Limit screen time for the first 48 hours to reduce eye strain
- Ensure the bandage lens is only removed by a medical professional
- Report any sudden pain or vision loss to the clinic immediately
