Laser Epithelial Keratomileusis (LASEK)
Laser Epithelial Keratomileusis (LASEK) is a type of refractive surgery that is similar to LASIK and PRK and As opposed to PRK, during a LASEK procedure, Dr. Bley preserves the epithelial layer as a replaceable flap instead of scraping or lasering it away. Generally LASEK is recommended for patients whose pupil size is an issue or that have corneas that are too thin for LASIK.
After the laser reshaping is complete, Dr. Bley cleans the surface of the newly shaped cornea, and then carefully replaces the epithelial flap. This flap is then allowed to dry slightly in order to start healing to the corneal stroma.
Steps to LASEK
- Under the excimer laser, the patient’s eye is numbed using anesthetic drops, and cleaned with a sterile tear solution.
- The eye is tracked to freeze it on the computer screen, and the area that will be reshaped is superimposed.
- A custom designed instrument is placed on the cornea surrounding the area to be reshaped and a solution is placed in this instrument for one minute to allow the epithelial flap to be created.
- After removing the solution and the instrument, Doctor uses another instrument of his own design to lift the epithelial flap from the underlying cornea.
- The wavelight laser is then used to precisely reshape the outermost stromal layer of the cornea.
- After the laser reshaping is complete, Doctor cleans the surface of the newly shaped cornea, and then carefully replaces the epithelial flap. This flap is then allowed to dry slightly in order to start healing to the corneal stroma.
- A bandage contact lens is then applied on the eye to hold the epithelial flap in place, and eye drops are started.
