Successful Surgical Correction of the Astigmatism by Customized Ablation PRK

The aim of this study was to determine astigmatism of the patients in pre and post customized ablation PRK status. In this hospital-based cross-sectional study, 92 otherwise healthy subjects with preoperative regular and irregular astigmatism ≥ 1.25 D who planned for customized ablation PRK with Technolas 217z100 excimer laser were enrolled. Six month postoperative refractive assessment was conducted and compare with preoperative values. The surgical success rate in astigmatic correction with this procedure was evaluated in 6 month postoperatively. Results showed patients aged 20 to 59 years (mean age, 39.09± 7.72 years), the mean preoperative astigmatism in automated refraction was 1.45 ± 2.51D which postoperatively became -0.87 ± 0.94 D with -1.67 ± 1.03 D change (p
