- 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.
