Laser Vision Correction: LASEK & LASIK

LASEK (Laser Epithelial Keratomileusis)

LASEK is a surgical procedure for correcting myopia (nearsightedness). During the surgery:

• The epithelial layer of the cornea is carefully removed.

• An excimer laser reshapes the cornea by removing a precise portion of the anterior boundary membrane and stroma to achieve a refractive correction.

• The epithelial layer naturally regenerates, requiring a recovery period with protective lenses to minimize discomfort and enhance healing.

LASIK (Laser-Assisted In Situ Keratomileusis)

LASIK is a widely used laser vision correction method that differs from LASEK in the surgical approach:

• A thin corneal flap is created, preserving the epithelial layer, anterior boundary membrane, and stroma.

• An excimer laser reshapes the stroma to achieve the desired vision correction.

• The corneal flap is repositioned without the need for sutures, allowing faster visual recovery than LASEK.

Diagnostic Tests Before Surgery

A comprehensive eye examination is required to determine suitability for laser vision correction, including:

• Analysis of the anterior segment of the eye

• Pupil size measurement

• Corneal curvature and thickness evaluation

• Fundus examination and visual field assessment

• Intraocular pressure measurement

Cost of Diagnosis & Treatment:

• LASEK: 2,300,000 KRW

• LASIK: 2,700,000 KRW
