Comparison of FS-LASIK and WFG FS-LASIK Procedures in Terms of Predictability, Efficacy and Safety

Purpose: To compare the results of femtosecond-assisted laser in situ keratomileusis (FS-LASIK) and wavefront-guided femtosecond-assisted laser in situ keratomileusis (WFG FS-LASIK) procedures in terms of predictability, efficacy and safety.

Material and Methods: One hundred and ten eyes of 55 patients with myopia and/or myopic astigmatism who had undergone FS-LASIK procedure were compared with 110 eyes of 55 patients with myopia and/or myopic astigmatism who had undergone WFG FS-LASIK procedure.

Results: In respect to age and sex, there was no significant difference between FS-LASIK and WFG FS-LASIK groups. Regarding preoperative and postoperative spherical, cylinderical and spherical equivalent values, uncorrected distance visual acuity (UDVA) and corrected distance visual acuity (CDVA), there was no significant difference between two groups. Predictability, efficacy and safety index values were high and similar in both groups.

Conclusion: Both FS-LASIK and WFG FS-LASIK are efficient, safe and predictable procedures for correction of myopia and myopic astigmatism.

Keywords: FS-LASIK, WFG FS-LASIK, efficacy, safety, predictability.
