| Purpose The aim of this study was to evaluate the visual and topographic outcomes of accelerated corneal collagen cross-linking (ACXL) in mild and moderate progressive keratoconus. Patients and methods This retrospective study evaluated the visual and topographic outcomes of 54 eyes of 36 patients of progressive keratoconus who had ACXL (9 mW/cm; 10 min). Data were collected 12 months after corneal collagen cross-linking. Results Uncorrected distance visual acuity was improved from 0.84±0.49 logMAR preoperatively to 0.79±0.3 logMAR postoperatively which is not statistically significant (=0.1). Corrected distance visual acuity was not significantly changed. The mean preoperative corrected distance visual acuity was 0.25±0.18 and 0.23±0.2 logMAR preoperatively and postoperatively, respectively (=0.4). Manifest spherical equivalent was not significantly changed, from −4.1±2.77 D preoperatively to −4.02±2.4 D postoperatively, which was not statistically significant (=0.4). There were no significant changes of steep , flat , average , and compared with preoperative measurements at 12 months. Conclusion ACXL (9 mW/cm; 10 min) is effective in stabilizing the keratoconus at 1-year follow-up. | ||||
