Femtosecond laser-assisted enhancements after laser in situ keratomileusis.

UNLABELLED: We describe a technique of femtosecond laser-assisted enhancement after primary LASIK with a mechanical microkeratome-created flap. The vertical side-cut incision by the femtosecond laser creates a wound configuration that decreases mechanical trauma to the epithelium and prevents epithelial cell migration. These factors may decrease the risk for post-LASIK enhancement epithelial ingrowth. FINANCIAL DISCLOSURE: No author has a financial or proprietary interest in any material or method mentioned.
