What Is LASEK/PRK?
PRK stands for Photo Refractive Keratectomy. In PRK, the upper protective layer of the cornea (epithelium) is removed with alcohol. And then the ophthalmologist is applying the laser to the cornea with the accurate strength. The epithelium then grows on itself again.
Lasek (Laser Assisted Epithelial Keratomileusis) is a laser eye surgery where the upper layer of the cornea (epithelium) is pushed aside. After the laser eye correction, this will be back in place. These treatments are often used when the eye does not qualify for LASIK treatment or IntraLASIK Femtosecond method.
Difference between Femto-Lasik, Lasek, PRK, Trans PRK is in the way in which the epithelium is loosened or is not replaced. In Lasek, PRK, Trans PRK, getting the best recovery in 3 to 7 days of rest is possible. You are not supposed to work and for one week you are not allowed to drive.
