LASEK (Laser Epithelial Keratomileusis)

LASEK (Laser Epithelial Keratomileusis)

LASEK is a laser surgical procedure used for the correction of refractive errors in the eyes. LASEK shares a similar goal with LASIK (Laser-Assisted In Situ Keratomileusis) but differs in application methods. This method is particularly chosen to correct vision impairments such as myopia, hyperopia, and astigmatism.

 

How LASEK Works

  • Epithelial Cell Removal: The LASEK procedure begins with the removal of a thin layer of cells called the epithelium from the surface of the eye.
  • Laser Correction: After removing the epithelial layer, laser energy reshapes the tissues beneath the cornea, correcting vision impairments.
  • Replacement of Epithelial Layer: Following laser application, the removed epithelial layer is repositioned to protect the treated area.

 

Advantages of LASEK

  • Thin Corneal Thickness: LASEK offers an option for individuals with thin corneas, as this method involves less cutting of corneal tissue.
  • Reversibility: LASEK is a reversible procedure; the epithelial layer can be replaced, providing flexibility to the treated individual.
  • Low Risk of Dry Eyes: The LASEK procedure minimizes the risk of dry eyes as it better preserves the balance of tears.
  • Versatility: LASEK may be a suitable option for patients with specific corneal thickness or those who have undergone previous corneal surgery.
