In LASEK, astigmatism, myopia, and hyperopia are corrected with laser. In eye surgery, the epithelial layer of the cornea is removed and the excimer laser is applied to the cornea. Then the epithelial layer is placed in its original position. At the end of the surgery, a lens is placed on the surface of the cornea to help repair the epithelium. The epithelium is repaired after 4-5 days and the patient’s vision will be complete after 2 months.
PRK and LASEK procedures are similar, except that the epithelium is placed back in its original position at the end of LASEK whereas it is removed in PRK. These two operations have no difference in terms of laser radiation and postoperative results.
FemtoLASIK is performed like LASIK. A layer (thin flap) is cut from the corneal surface with a surgical instrument in LASIK and by a femtosecond laser device in FemtoLASIK. High precision incision of corneal surface, fewer complications, and higher safety are some advantages of femtoLASIK.
