title: Clinical outcomes of LASIK for myopia using the SCHWIND platform with ocular wavefront customized ablation.
abstract: OBJECTIVE
  To evaluate the clinical outcomes of aspheric ocular wavefront ablation profiles in LASIK treatments.
  
  
  METHODS
  Thirty eyes treated by ocular wavefront were retrospectively analyzed at 6-month follow-up. Custom Ablation Manager (CAM) software was used to plan wavefront-customized aspheric treatments, and the ESIRIS system was used to perform ablations (SCHWIND eye-tech-solutions). Outcomes were evaluated in terms of efficacy, predictability, refractive outcome, safety, and pre-and postoperative wavefront aberration analysis (SCHWIND Ocular Wavefront Analyzer).
  
  
  RESULTS
  At 6 months postoperatively, 47% of eyes achieved uncorrected visual acuity 20/20 or better. Average defocus was reduced from -3.49+/-2.38 diopters (D) preoperatively (range: -10.63 to 0.00 D) to -0.14+/-0.31 D postoperatively (range: -1.75 to 0.00 D). Astigmatism was reduced from -0.81+/-1.15 D (range: -4.25 to 0.00 D) to -0.25+/-0.37 D (range: -1.25 to 0.00 D). Eighty-six percent of eyes were within +/- 0.50 D. Best spectacle-corrected visual acuity (logMAR) improved from +0.12+/-0.08 (range: 0.0 to +0.2) to -0.05+/-0.13 (range: -0.2 to +0.2) (P=.04). The treatment did not change coma or spherical aberration, and reduced the trefoil from 0.21+/-0.13 microm (range: 0.05 to 0.53 microm) to 0.08+/-0.13 microm (range: 0.01 to 0.39 microm) (P=.002).
  
  
  CONCLUSIONS
  The study results indicate that the aspheric ocular wavefront customized CAM approach for planning ablation volumes is safe and effective.
