LASIK, LASEK and PRK

  • What is the difference between LASIK, LASEK and PRK?

    LASIK

    This surgery is done on the surface of the eye. A laser first creates a flap of corneal tissue. The flap is folded back to expose the inner area of the cornea. The excimer laser is used to remove very thin layers of tissue. The flap is put back into place on the front surface of the eye.

    LASEK

    During this surgery, no corneal flap is created. The surface of the eye is brushed to the side to expose the inner layer of the cornea. The excimer laser is used to remove very thin layers of tissue. The surface of the eye is put back into place. There are also no flap complications (problems) since one was not created.

    PRK

    This surgery is done on the surface of the eye. No corneal flap is created. The excimer laser is used to remove very thin layers of tissue. PRK may be a good choice for you if you have:

    • larger pupils
    • thin corneas
    • dry eyes
    • other corneal issues (such as scar tissue and dry eyes)
    • long-term concerns about LASIK corneal flaps
