Purpose: To investigate the results of Advanced Surface Ablation (ASA) coupled with `smoothing` to smooth the ablation surface after covering masking fluid. Methods: ASA was performed in 61 eyes with ablation depth of more than 75 μm. The mean refractive error was -5.88 ± 1.27 D and mean ablation depth was 102.93 ± 12.06 μm. Smoothing was performed in all patients (mean depth 16.79 ± 2.43 μm, mean diameter 8.77 ± 0.16 mm). Customized Aspheric Transition zone (CATz) was used in the laser algorithm. Results: The mean refractive error was -0.29 ± 0.41 D at postoperative 6 months and 97% of patients had an UCVA of 1.0 or better at postoperative 6 months. There was no statistically significant difference in magnitude of high-order aberrations at postoperative 6 months. The magnitude of total spherical aberrations increase was 0.084 μm at postoperative 6 months (p＜0.05, paired t-test). The cornea was maintained clear in the majority of eyes. Conclusions: Excellent results were obtained by ASA coupled with `smoothing` in high myopia patients with an ablation depth greater than 75 μm. J Korean Ophthalmol Soc 2012;53(3):365-371
