Abstract:
OBJECTIVES: To investigate the results of AdvancedSurface Ablation (ASA) coupled with "smoothing" to smoothen ablation surface after covering masking fluid. METHODS: ASA was performed in 48 eyes that had myopic refractive error. The case with ablation depth over 100 microm was assigned into subgroup. Mean refractive error was -5.71 +/- 1.25D and mean ablation depth was 101.74 +/- 11.15 microm. Smoothing was performed in all patients (mean time 15.59 +/- 1.34 seconds, mean diameter 8.60 +/- 0.21 mm). RESULTS: Mean refractive error was -0.16 +/- 0.42D, -0.30 +/- 0.40D at postoperative 3 and 6 months. 92% and 96% of patients had an uncorrected visual acuity (UCVA) of 1.0 or better at postoperative 3 and 6 months, respectively. There was no statistically significant difference in magnitude of high order aberrations at postoperative 6 months. Cornea was maintained clear in the majority. CONCLUSIONS: Excellent results were obtained by ASA coupled with "smoothing" in high myopia patients. And subgroup with ablation depth over 100 microm was also obtained satisfactory results.
