Macrostriae demonstrating gross folds in the visual axis. Flap suturing has been successfully removed the striae. Note the postoperative smooth central flap.

  • Gross, linear folds in the visual axis may cause reduced vision due to optical aberrations and irregular astigmatism.
  • Causes:
    • Thin or large flap
    • Excessive dehydration of the flap
    • High myopic or hyperopic correction
    • Uneven smoothing of the corneal flap surface after the primary procedure
  • Treatment:
    • If identified early, the flap may be relifted, stretched, hydrated and gently smoothed to remove the striae.
    • In recalcitrant cases, suture placement at the flap edge has been reported to be successful to remove the striae.
