LASEK Eye Surgery in Korea

Definition

LASEK (Laser-Assisted Sub-Epithelial Keratectomy) is a type of refractive surgery that improves vision by reshaping the cornea using an excimer laser. The procedure involves gently removing the outermost layer of the cornea (epithelium) and correcting the underlying corneal tissue to restore clear vision.

How the Procedure Works

Unlike LASIK, LASEK eye surgery does not create a corneal flap. Instead, only the corneal epithelium is removed, and the laser is used to precisely reshape the cornea.

This flapless approach helps preserve corneal stability and reduces the risk of flap-related complications caused by external impact. With advanced laser systems and precise surgical planning, LASEK aims to minimize unnecessary tissue damage while achieving accurate and predictable visual outcomes.

Who Is a Good Candidate?

LASEK is often recommended for patients with thin corneas where flap creation may be difficult or risky. It is also suitable for correcting refractive errors such as myopia, astigmatism, and hyperopia.

This procedure may be particularly beneficial for individuals with active lifestyles or those who require stronger long-term corneal stability. However, suitability may vary depending on corneal condition, refractive error, and overall eye health, so a comprehensive eye examination is necessary before surgery.

LASEK eye surgery is widely recognized as a structurally stable and reliable vision correction method. As a flapless laser eye surgery, it preserves more of the natural corneal structure, making it a strong option for patients who prioritize long-term safety and stability.

• Structurally Stable Without a Corneal Flap
  One of the key LASEK benefits is that it does not require the creation of a corneal flap. This means there is minimal structural alteration to the cornea, allowing it to maintain its natural strength over time. As a result, patients can expect greater long-term stability compared to flap-based procedures.

• Suitable for Active Lifestyles and External Impact Risk
  Because LASEK does not involve a corneal flap, there is no risk of flap displacement caused by external impact. This makes LASEK laser eye surgery particularly suitable for individuals with active lifestyles, including athletes, military personnel, or those working in physically demanding environments.

• Preserves More Corneal Tissue for Future Flexibility
  LASEK preserves more corneal tissue compared to LASIK, which can be an important advantage for long-term eye health. This increased tissue preservation may provide greater flexibility for potential future vision correction enhancements if needed.

• Effective for Thin Corneas and High Myopia
  LASEK is often recommended for patients with thin corneas, where creating a flap may not be safe. It is also a suitable option for patients with high myopia, as it allows vision correction without compromising corneal integrity.

• Designed to Minimize Night Vision Disturbances
  With advanced pre-surgery diagnostics and customized laser planning, LASEK can help reduce visual disturbances such as glare or halos at night. By considering individual pupil size and higher-order aberrations, the procedure is optimized to enhance overall visual quality, especially in low-light conditions.

LASEK is an excellent option for patients who prioritize long-term stability over rapid recovery. While recovery may take slightly longer compared to LASIK, its flapless structure makes it a safer and more stable solution for certain eye conditions and lifestyles.

  Patients with Thin or Irregular Corneas

  LASEK is often recommended for patients with thin corneas or irregular corneal shapes, where creating a flap may not be suitable. Because LASEK does not require a corneal flap, it reduces structural stress on the cornea while still allowing effective vision correction.

• 

  Individuals with Active Lifestyles or High Impact Risk

  For those engaged in physically demanding activities—such as athletes, military personnel, police officers, or firefighters—LASEK can be a safer choice. Since there is no corneal flap, there is no risk of flap displacement due to external impact.

  Those Who Prioritize Long-Term Stability Over Fast Recovery

  Patients who value long-term vision stability and corneal preservation over immediate recovery speed may benefit from LASEK. Its tissue-preserving approach helps maintain consistent vision outcomes over time.

Before LASEK eye surgery, a comprehensive pre-surgery screening is essential to evaluate each patient’s eye condition and determine the safest and most effective treatment plan. At EYE Plus Eye Clinic, advanced diagnostic equipment and detailed eye examinations are used to analyze corneal structure, measure corneal thickness, and assess overall eye health. This thorough evaluation helps ensure both surgical safety and optimal visual outcomes.

• Corneal Topography Analysis

  Corneal topography is used to analyze the curvature and symmetry of the cornea. This test helps detect irregularities such as keratoconus and evaluates whether the cornea is structurally suitable for LASEK.

• Corneal Thickness Measurement

  Accurate measurement of corneal thickness is critical in LASEK planning. This test evaluates the total corneal thickness and the amount of tissue available, helping determine whether the procedure can be safely performed.

• Higher-Order Aberration Analysis

  This analysis evaluates subtle visual distortions that may cause glare, halos, or reduced night vision quality. By identifying these factors, the surgical plan can be customized to improve overall visual clarity.

• Pupil Size Measurement

  Measuring pupil size, especially under low-light conditions, helps predict the risk of night vision disturbances after surgery. This information is used to optimize laser treatment planning.

• Intraocular Pressure (IOP) Measurement

  Intraocular pressure is measured to assess eye health and screen for conditions such as glaucoma. Maintaining proper eye pressure is an important factor in ensuring safe vision correction surgery.

• Comprehensive Eye Health Examination

  A detailed examination of the retina and optic nerve is performed to identify any underlying eye conditions that may affect vision or surgical outcomes. This step ensures that LASEK is both safe and appropriate for the patient.
