- Clinical features:
- Symptoms:
- Fine "microstriae" usually do not affect vision
- "Macrostriae" in the visual axis may cause reduced
vision due to optical aberrations and irregular astigmatism
- Signs: fine or gross, linear folds commonly
seen in the corneal flap after LASIK.
- Causes: thin or large flap, excessive dehydration
of the flap, high myopic or hyperopic correction and 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.
