PRK/Lasek is performed directly on the corneal surface, after gently sliding aside the surface "skin" layer called the epithelium. No flap is created, in contrast to LASIK, making it a simpler one stage procedure. (See figure). Sometimes the epithelium is slid back in to place (Lasek) although this is not crucial as a fresh layer of epithelium grows in during the first few days. Usually the old epithelium is simply removed (PRK). A contact lens is placed on the eye for comfort and to aid healing. This is generally removed after about 4 days.
Healing is slightly slower than for LASIK. Your eyes may be sensitive and vision may be blurry for the first few days as the new healthy epithelium grows in. This is a small price to pay for the years of great vision to follow and a very safe form of laser treatment.
PRK is the original form of laser vision correction with more than 15 years experience. Longterm results show excellent stability and patient satisfaction.
It is now practised in a more advanced fashion, including newer techniques for removing the epithelium, superior laser performance, and techniques for improving healing and better post-operative management.
Overall results are as successful as for LASIK. Although recovery is slightly slower, many patients prefer PRK as it is simpler and extremely safe with no need to cut a flap. PRK/Lasek is the only option for candidates with thin or slightly irregular corneas.
