LASEK “No Flap” Procedure

LASEK (laser epithelial keratomileusis) is a fairly new type of PRK, where laser energy is applied directly to the eye's outer surface for reshaping and vision correction. There are differences among LASIK, PRK and LASEK laser refractive eye surgeries.

• A LASEK “no flap” procedure involves preserving the extremely thin epithelial layer by lifting it from the eye's surface before laser energy is applied for reshaping. After the LASEK procedure, the epithelium is replaced on the eye's surface.
• In LASIK eye surgery procedures, a thin flap is cut into the eye's surface and then lifted. Laser energy is applied to the eye for reshaping after which the flap is replaced to serve as a type of natural bandage for quicker healing.
• In PRK laser surgery, as in LASEK surgery, no flap is cut into the eye's surface, as it is with LASIK procedures. Alternatively, laser energy is applied directly to the eye's surface. The ultra thin, outer layer of the eye (epithelium) is removed completely by laser energy during PRK surgery, which eventually grows back.

Although all three of these laser refractive eye surgeries are extremely safe and effective, there are risks & complications associated with LASIK, LASEK and PRK procedures. You should speak with your eye surgeon to make sure that you have a complete understanding of the surgery you need.
