Clinical Outcomes of Z-LASIK for Myopia in Ocular Wavefront Customized Ablations
Narrative Responses:
Purpose
Evaluation of aspheric customized Z-LASIK treatments with AMARIS using Ocular Wavefront Customized Ablations.
Methods
The last twenty-five patients (50 eyes) treated for myopia up to -6D and astigmatism up to 3D using Z-LASIK and AMARIS ocular WFG ablations (based on irx3 H-S aberrometer) have been reviewed at 6-month follow-up. Clinical outcomes were evaluated in terms of predictability, refractive outcome, safety, wavefront aberration, and contrast sensitivity.
Results
6-month postoperatively, mean residual defocus was +0.14±0.40 D and mean residual astigmatism magnitude 0.50±0.27 D. Thirty-six percent eyes were within ±0.25 D of emmetropia and 92% within ±0.75 D. The achieved refractive changes (in defocus, and cardinal and oblique astigmatisms) were significantly correlated with intended corrections, the regression slopes were very close to the ideal corrections.
Conclusion
6 months post-op results prove the predictability and stability of the correction by OW customisations. Ocular WFG treatments with AMARIS based on Hartmann-Schack aberrometry provide excellent aberration correction.
