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.
