Purpose: The correction of refractive errors using laser in situ keratomileusis (LASIK) has become the primary refractive procedure worldwide. The purpose of this study was to evaluate LASIK within a retrospective cohort.
Patients and methods: The mean preoperative spherical equivalent for the 34 consecutively treated eyes was -6.67+/-2.69 D. The LASIK operations were performed by a Hansatome microkeratome (Bausch and Lomb) and a scanning spot excimer laser (Technolas Keracor 217, Bausch and Lomb). For pre- and postoperative analysis the Datagraph med software (Version 2.7) was used.
Results: None of the treated eyes lost 2 or more lines of best-corrected visual acuity (BCVA). At the 36-month examination the spherical equivalent had changed to -0.47 D (mean increase of myopia: 0.13 D). No long-term complications were found in the study period.
Conclusion: LASIK with superior hinge and scanning spot excimer ablation is an effective treatment for the correction of myopia and myopic astigmatism in the refractive range described above.
