No-Cut, No-Flap LASEK

LASEK (Laser Epithelial Keratomileusis)

LASEK or Laser Epithelial Keratomileusis is very similar to one of the first laser vision correction procedures known as PRK. PRK (photorefractive keratectomy) was actually approved about a year earlier than the very popular LASIK procedure. Like PRK, LASEK does not involve the creation of a FLAP. LASEK is almost exactly like LASIK except there is NO flap. The excimer laser is used to reshape the cornea in the LASEK procedure. First an ophthalmologist uses a local anesthetic to numb the eye. Once the eye is suitably under the local anesthetic the ophthalmologist will then apply a diluted solution to the epithelium (commonly referred to as the outer surface of the cornea). Once the tissue is loosened from the stroma the tissue is moved to one side and the excimer laser is used to make the necessary vision correction. Once the ophthalmologist has completed the laser procedure the epithelium is placed back into its original position. LASEK and PRK both have a longer recovery period than LASIK and a contact lens bandage is typically applied to aid in healing. For a complete list of post operative instructions regarding this procedure please consult a medical ophthalmologist.

LASEK is a good eye surgery procedure that can ensure excellent visual quality after full recovery. Despite the fact that LASIK has a shorter recovery period the visual results post operatively are quite similar. Patients might consider a surface treatment over LASIK for a variety of reasons. If a patient has thin corneas and does not have enough corneal tissue for LASIK some doctors might suggest LASEK or PRK. The main difference between LASEK and PRK is that during PRK the entire epithelial layer is removed where the laser treatment will occur. As previously mentioned the LASEK procedure involves pushing aside the epithelium and then repositioning after the laser treatment. After the procedure new and healthy corneal cells will grow over the treatment area.
