英文摘要

PURPOSE: To evaluate and compare the thickness and the morphology of femtosecond and mechanical microkeratome LASIK flaps using anterior segment optical coherence tomography (AS-OCT).

METHODS: Bilateral LASIK was performed in 132 eyes from 61 myopic patients. Flaps were created in 72 eyes using the WaveLight FS200 femtosecond laser (WaveLight GmbH, Erlangen, Germany) and in 50 eyes using the Moria microkeratome (Moria SA, Antony, France). AS-OCT was used 1 week postoperatively to evaluate the thickness of 17 points across each flap, which were 0, 2, and 3.5 mm to the corneal vertex on the horizontal, vertical, 45 degrees, and 135 degrees meridians.

RESULTS: The mean central flap thickness was 105.53 +/- 5.86 mu m in the WaveLight group and 132.96 +/- 13.91 mu m in the Moria group (P < .001). The difference between the achieved and the intended flap thickness (accuracy) was 6.17 +/- 3.98 and 23.60 +/- 12.64 mu m, respectively (P < .001). The standard deviation within individual flap (uniformity) was smaller in the WaveLight group. The symmetry and regularity were also better in the WaveLight group. Flap morphology showed a more regular planar shape in the WaveLight group and a meniscus shape in the Moria group.

CONCLUSIONS: AS-OCT showed that the flaps created by the WaveLight femtosecond laser were more accurate, reproducible, and uniform than those created by the Moria microkeratome.
