Clinical Outcomes of Advanced Surface Ablation with Smoothing

• Lee SU

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.
