Abstract:
PURPOSE: To investigate the clinical outcome based on topographic supported customized corneal ablation (TOSCA). METHODS: The 20 patients (20eyes), who had already undertaken excimer laser surgery at least 6 months ago, resulting in decrease of best-corrected visual acuity, were included. Topography-guided corneal ablation was performed to correct de-centered ablation or irregular astigmatism using with the Mel-70-scan (ascleapion Meditec Inc. Germany) equipped with a Gaussian spot beam. RESULTS: The average uncorrected visual acuity (UCVA) and best corrected visual acuity (BCVA) in Log MAR scale was 0.52 +/- 0.35 and 0.33 +/- 0.14, preoperatively. The average of UCVA and BCVA was improved to 0.29 +/- 0.29 and 0.11 +/- 0.14, respectively after TOSCA was done. It was statistically significant difference (p<0.05). CONCLUSIONS: TOSCA may be considered as effective method to improve BCVA in patients who suffer from decrease of BCVA in duced by decentered ablation.
