LASEK (Laser Assisted Sub-epithelial Keratomileusis) is a corneal refractive surgery that has improved upon the weak points of PRK and LASIK surgery. Using special equipment, LASEK only peels off approximately 50 micrometers of the corneal epithelial layer before beginning laser ablation. LASEK has made it possible for patients who are poor candidates for LASIK (due to small eyes, thin cornea) to achieve clear vision.
1. The surgical area is marked and a 20% alcohol solution is applied to the corneal epithelium.
2. The alcohol loosens a layer of epithelium which is then easily removed.
3. A laser reshapes the cornea curvature by ablation
4. A protective lens is applied to the reshaped cornea.
