When someone does their research on laser vision correction, dr. carlson performing a laser vision correction procedurethey usually think of, or find their way to the popular LASIK eye surgery. What one may not know is that there are many different types of laser vision correction and depending on the severity or condition of your eyes, LASIK eye surgery may not be the solution.

Often if an individual has a corneal distortion, PRK or LASEK may be a more beneficial procedure than LASIK. The PRK procedure was in fact the first type of laser eye surgery for vision correction and is the predecessor to the popular LASIK procedure everyone has come to know. Like the LASIK procedure, PRK and LASEK reshape the cornea to correct one’s vision by using an excimer laser. The procedures differ in the preparation of the cornea prior to the excimer laser treatment. PRK and LASEK are often an optimal approach for a number of reasons.

What’s The Difference?

  • PRK and LASEK involve removing the surface cells on the cornea (the epithelium), instead of creating a corneal flap. In the LASEK procedure, the surface epithelial cells are partially preserved until new cells grow back. In the PRK procedure, the cells on the surface of your cornea are removed to re-shape your cornea.
  • PRK does offer some distinct benefits. Because the PRK procedure does not create a corneal flap, the entire thickness of the underlying stroma is available for treatment.
  • PRK and LASEK are ideal if you have corneal distortions and do not qualify for LASIK.
  • Though PRK recovery can take a bit longer than recovery from LASIK eye surgery, PRK is still commonly performed and offers advantages over LASIK for some patients.


So the big question; which procedure is right for you? Few ophthalmologists perform PRK or LASEK procedures and Claris Eye Care & Surgery’s own, Dr. Carlson, is experienced performing these as they are his most routinely performed procedures.
