Folds and striae in laser in situ keratomileusis flaps.

Purpose: To classify striae and folds seen after laser in situ keratomileusis.

Methods: The authors' experience and review of the literature form the basis for the proposed classification.

Results: Five types of folds and striae are described: loose epithelium, hinge ridge, hinge fold, deep stromal striae, deep epithelial/Bowman's striae.

Conclusion: Linear striae in laser in situ keratomileusis flaps have a variety of appearances and different postoperative courses that require accurate diagnosis and management.
