PURPOSE
We evaluate the clinical outcomes after wavefront-guided LASIK using the Fourier algorithm. METHODS: The uncorrected visual acuity (UCVA), best corrected visual acuity (BCVA), manifest refraction measured with auto refractometer, spherical aberration, coma, trefoil, total high order aberrations and contrast sensitivity of daytime and nighttime in 23 eyes of 13 patients who had undergone wavefront-guided LASIK using the Fourier algorithm preoperatively and at 1 day, 1 week, 1 month, 2 months and 6 months postoperatively. RESULTS In the wavefront-guided LASIK using the Fourier algorithm, the preoperative UCVA was 0.13+/-0.10 and increased to 1.02+/-0.29 (p=0.000) at 6 months postoperative, the postoperative spherical equivalent was -6.48+/-1.68D and 1.02+/-0.29 (p=0.000) at 6 months postopertive. The total high order aberration was 0.324+/-0.107 preoperative and 0.338+/-0.167 (p=0.810) at 6 months postoperative in wavefront-guided LASIK using the Fourier algorithm. Preoperative daytime contrast sensitivity increased preoperative from 0.75+/-0.24 to 1.11+/-0.35 (p=0.026) at 12 cpd, and that at 6-month preoperative increased from 1.05+/-0.26 to 1.41+/-0.41 (p=0.003) at 7.5 cpd and from 1.45+/-0.34 to 1.69+/-0.42 (p=0.028) at 4.8 cpd. CONCLUSIONS: The clinical outcomes of wavefront-guided LASIK using the Fourier algorithm after 6 months were stable visual acuity, no increase in high order aberration and no increase in contrast sensitivity. |
