A slight variation on the traditional LASIK procedure is becoming available, LASEK. This procedure may be an option for patients who are not good candidates for the traditional procedure.
What is LASEK?
LASEK is a relatively new surgery that utilizes a trephine to create an epithelial flap (as opposed to a deeper stromal flap with LASIK) and an alcohol solution to preserve the epithelial cells. Once the epithelial flap is created and lifted, the treatment proceeds as for traditional PRK, with light smoothing at its conclusion. Then, the epithelial flap is repositioned with a small spatula.
LASEK preserves approximately 160 microns more corneal tissue, on average, than a typical LASIK procedure.
