Objective To evaluate and compare the thickness and morphology of laser in situ keratomileusis (LASIK) flaps created by either the WaveLight FS-200 femtosecond laser or the Moria microkeratome M2 90 using anterior segment optical coherence tomography (AS-OCT).Methods This was a prospective case-control study.Bilateral LASIK was performed on 61 myopic patients.Flaps were created using the WaveLight FS-200 femtosecond laser in 72 eyes and the Moria M2 90 microkeratome in 50 eyes.The thickness at 17 points across each flap,0 mm,±2 mm,and ±3.5 mm to the corneal vertex on the horizontal,vertical,45° and 135° meridians,were evaluated using a Visante AS-OCT at 1 week postoperatively.An independent t test was used.Results The central flap thickness of the WaveLight group was 105.53±5.86 μm,while it was 132.96±13.91 μm in the Moria group (t=-13.16,P＜0.01).The difference between the achieved and the intended flap thickness (accuracy) was 6.17±3.98 μm and 23.60±12.64 μm,respectively (t=-15.20,P＜0.01).The standard deviation of thickness in the 17 points within an individual flap (uniformity) was 4.07±0.94 μm in the WaveLight group and 8.48±2.35 μm in the Moria group (t=-12.60,P＜0.01).The index S (Symmetry) of Moria group (33.81±11.28 μm) was significantly smaller in the WaveLight group (68.46±26.66 μm) (t=-8.67,P＜0.01).Conclusion AS-OCT showed that the flaps created with the WaveLight FS-200 femtosecond laser were more accurate,reproducible,and uniform than those created with the Moria M2 90 microkeratome.
