Flap Sliding Technique for Managing Flap Striae following Laser In Situ Keratomileusis

Figure 5

Anterior segment optical coherence tomography (AS-OCT) scans of a 24-year-old woman who developed flap striae following LASIK. (a) Images obtained before flap sliding show dome-shaped [13] irregularities of the flap (arrows). (b) One hour after undergoing the flap-sliding procedure, the dome-shaped irregularities have improved and now appear as fine corrugations on the flap surface. (c) Two days after undergoing flap sliding, flap striae have completely resolved and the corneal surface appears smooth. (d) Images of the flap edge obtained before flap siding show gapping between the flap edge and the exposed stromal bed. (e) One hour after flap sliding, flap gapping is no longer apparent and epithelial cells have aggregated at the flap edge (arrow). (f) Two days after flap sliding, the flap is perfectly aligned and no epithelial irregularities at the flap edge are visible.
