Laser Epithelial Keratomileusis (LASEK)
LASEK is a relatively new laser vision correction procedure similar to LASIK. The primary difference is that for LASEK the flap is created from corneal epithelium alone, while in traditional LASIK the stroma is also affected. Once the epithelium has been pulled aside, the LASEK surgeon applies the excimer laser to the surface of the cornea (as in PRK laser vision correction).
The advantages of LASEK laser vision correction include:
- Much less tissue is temporarily removed than in LASIK surgery
- A microkeratome is not needed
- Infections can be treated more readily
- Patients with dry eyes may benefit from LASEK
Note: Visual recovery is not as rapid as with LASIK and some patients endure greater discomfort.
