EpiLASIK – PRK

EpiLASIK - PRK

EPI-LASIK is a newer laser eye procedure that takes characteristics from both LASIK and LASEK procedures.

  • EPI-LASIK Step 1:

    The cornea’s outer layer, the epithelium, is made up of many cells. A special instrument is used to create a very thin layer of the outermost cells. This layer is pushed off the cornea surface.

  • EPI-LASIK Step 2:

    Using Wavefront technology, the VISX S4 Laser with Iris Recognition applies a cool beam of light, which gently reshapes the cornea to correct vision.

  • EPI-LASIK Step 3:

    The thin layer of cells created in Step 1 is gently placed back in its original position. In some cases the thin layer of cells is removed. A protective contact lens is placed over the cornea and healing begins immediately.


PRK – Photorefractive Keratectomy

PRK is a treatment for mild to moderate myopia (nearshightedness), hyperopia (farsightedness) or astigmatism. PRK was performed in the early 1980’s and was FDA approved in 1995 and has proven to be a successful means for improving vision.

  • PRK Step 1:

    An alcohol solution is applied to the epithelium, or outer layer of the cornea. The solution loosens the edges of the epithelium.

     

  • PRK Step 2:

    Using Wavefront technology, the VISX S4 Laser with Iris Recognition applies a cool beam of light, which gently reshapes the cornea to correct vision.

     

  • PRK Step 3:

    A computer guided and very precise Excimer laser is applied directly to the surface of the cornea. The laser uses a cool ultraviolet light beam to precisely ablate or remove very tiny bits of tissue from the surface of the cornea, reshaping it and improving vision.
