Abstract Details

Purpose:

To evaluate the accuracy of SBK microkeratome in flap creation during myopic LASIK surgery using anterior segment optical coherence tomography.

Setting:

Eye Care Center, Maadi, Cairo, Egypt

Methods:

Flaps were created using the One Use-Plus SBK microkeratome (intended flap 90µm) in 100 eyes of 50 patients. Flap thickness was measured using anterior segment OCT one week after surgery.

Results:

The mean achieved central flap thickness in both eyes was 88.67±7.19, 1.33µm thinner than the intended thickness with a p value of 0.067 which is statistically insignificant (p>0.05). The mean achieved central flap thickness in the right eye was 88.56 ± 7.95 μm, (70 μm to 112µm), 1.44 µm thinner than the intended 90 µm (difference from intended thickness -1.44 ±7.95) thickness with a p value of 0.206 which is statistically insignificant ( p>0.05). The mean achieved central flap thickness in the left eye was 88.78 ± 6.41 μm,(77µm to 105µm) showing a difference from intended thickness of -1.22±6.41µm deviation from the intended thickness that is statistically insignificant (p value of 0.185, p>0.05).

Conclusions:

In the current study it was found that the use of the One Use-Plus SBK microkeratome for creating an SBK flap is safe and effective. The results of the current study were comparable to the results in previous studies using femtosecond laser. In conclusion, our results indicate that the One Use-Plus SBK microkeratome created flaps with good central accuracy, predictability and reproducibility, with variable increase in flap thickness towards the periphery.
