Narrative Responses:

Purpose
To compare subjective outcomes of standard versus inverted side cut LASIK flaps.

Methods
The dominant eye of 61 myopic LASIK patients was randomized to receive a 9 mm, 105 um thick, superiorly-hinged flap with either a 70-degree side cut (60-kHz IntraLase FS) or a 130-degree inverted side cut (150-kHz IntraLase iFS); the non-dominant eye received the alternative. Subjects completed the validated, Rasch-tested, linear-scaled Quality of Vision (QoV) questionnaire preoperatively and postoperatively.

Results
There were no statistically significant differences between the groups for the 30 QoV parameters at 6 months (all P>0.05).

Conclusion
Inverted side cut flaps may not affect subjective quality of vision outcomes.
