Purpose
Estimation of the results of Femto-LASIK operation with MEL-80 excimer laser using VISUMAX laser microkeratome in the eyes after keratometry below 38D (flat cornea).

Methods
Six eyes of 5 patients were studied. During Femto-LASIK corneal flap with planned thickness of 100 microns with a 12 o’clock hinge was formed with VISUMAX laser microkeratome (Carl Zeiss Meditec). Corneal ablation was performed with MEL-80 excimer laser (Carl Zeiss Meditec), optic zone diameter was 6 mm. Follow-up was from 3 to 6 months.

Results
Mean uncorrected visual acuity before surgery was 0.34. After surgery it has significantly increased up to 0.81. Mean corrected visual acuity before surgery was 0.91. After surgery it has insignificantly changed and made 0.89. Mean spherical equivalent before surgery was +2.33 D. After surgery it has significantly decreased up to -0.25.

Conclusion
Femto-LASIK is an effective and safe technology for correction of refractive errors in the eyes after radial keratotomy with keratometry below 38D (flat cornea).
