These data were imported and used unmodified by the InnovEyes algorithm to automatically calculate and optimize correction of lower- and higher‑order aberrations (HOAs) treated by the EX500 ablation profile. Visual acuity, refractive error, HOAs, and patient satisfaction were evaluated over 3 months.Results: A total of 106 patients (212 eyes) completed the study and were included in the analysis. Mean preoperative manifest refraction spherical equivalent (MRSE) was − 3.38± 1.76 D. At Month 3, uncorrected distance visual acuity was 20/20 or better in 208/212 (98.1%) eyes, and it was the same as, or better than, the preoperative best-corrected distance visual acuity (CDVA) in 162/212 (76.4%) eyes; 76/212 (35.8%) eyes gained ≥ 1 line of CDVA. MRSE was within ± 0.5 D in 195/212 (92.0%) eyes. Additionally, 201/209 (96.2%) eyes had no change (defined as a change between − 0.1 μm and 0.1 μm, inclusive) in HOAs, and 105/106 (99.1%) patients reported to be satisfied with the results.Conclusion: Customizing ray-tracing Femto LASIK with this platform appeared safe and effective in correcting myopic astigmatism and also achieved a significant percentage of eyes gaining lines of vision, potentially by addressing HOAs, along with a consistently high level of patient satisfaction.Keywords: myopic astigmatism, higher-order aberrations, manifest refraction spherical equivalent, corrected distance visual acuity |
