Abstract

Introduction:
This is a prospective comparative clinical study conducted to assess the safety , effectiveness, and complications of Intralase femtosecond laser (FSL) compared to Moria M2 microkeratome (MK) in high myope.

Methods :
This study consisted of 51 myopic eyes, divided into two groups( A & B) . Twenty-five eyes in group A in which the flap was created by Intralase FSL, while twenty-six eyes in group B in which the flap was created by Moria M2 MK. Refractive , keratometric and flap complications were compared preoperative and 6 months postoperative by using the intraoperative subtraction pachymetry . (Scheimpflug imaging (CSO, Florence, Italy).

Results:
No substantial difference was found as regarding postoperative manifest sphere ,astigmatic and keratometry .In group A mean postoperative actual flap thickness was98.12 ± 16.1 μm and in group B it was100.6 ± 20.1 μm with statistically significant difference P value( 0.001).
Conclusion:
Both the femtosecond laser and the mechanical microkeratome are safe and effective in correcting myopia, with no statistically significant difference during 6-month follow-up between the two groups. The femtosecond laser has better flap creation than the microkeratome .
