Abstract Details

Purpose:

Estimation of the results of FemtoLASIK operation performed with VisuMax femtosecond laser and MEL 80 excimer laser and accompanied by central non-penetrating gas breakthrough.

Setting:

IRTC Eye Microsurgery Center Ekaterinburg, Russia

Methods:

The study included a group of patients with myopia and complex myopic astigmatism undergoing FemtoLASIK operation with MEL 80 excimer laser (Carl Zeiss Meditec, Germany) with 6 mm optic zone diameter. The group included 15 patients (16 eyes) in whom corneal flap formation was performed with VisuMax 500 kHz femtosecond laser (Carl Zeiss Meditec, Germany) with preset flap thickness of 100 microns accompanied by central non-penetrating gas breakthrough and central island on the stromal bed. During corneal flap separation from the stromal bed no perforation in the central part of the thinned flap was marked.

Results:

Uncorrected visual acuity before the operation was 0.13 ± 0.16, after the operation 0.94 ± 0.11(p<0.05). Spherical equivalent (SE) before the operation was –4.53 ± 4.48 D, after the operation – 0.09 ± 0.26 D. Best corrected visual acuity before the operation was 0.94 ± 0.13, after the operation 0.94 ± 0.14.

Conclusions:

FemtoLASIK operation performed using VisuMax femtosecond laser and accompanied by central non-penetrating gas breakthrough can be successfully completed with good functional results in case of precision separation of the corneal flap from the stromal bed.
