Understanding the Real Effect of the High-Order Aberrations after Myopic Femto-Lasik

In this work we try to understand the real effect of increase in aberrations after Femto-LASIK surgery on patient’s final visual quality, specifically when acuity measurement is considered. A clinical study with 37 eyes 20 patients that underwent myopic and different personalized eye model simulations were carried out. study, correlations between pre- postoperative parameters analysed. Eye (based data) provided vision quality before surgery. Our main results showed a significant was obtained surgery; however, no differences found preoperative corrected distance (CDVA) uncorrected (UDVA). This absence could be explained by performing three would cover most possible situations. Simulations implemented considering pupil size 2.5 mm data each patient. Results (VA) change are determined high-order (HOAS) their but measured under photopic conditions. conclusion, customized analysis higher-order scotopic pupils better predicts patient Lasik
