Abstract Background & Objectives: keratectasia is a sight-threatening complication that may occur after LASIK. The purpose of this study was to evaluate the effects corneal crosslinking with riboflavin and UVA for treatment of this complication. Material & Methods: Twenty-three eyes of 12 patients in Non-Randomize Cohort study (referred to Navididegan Clinic) were selected for corneal crosslinking. Standard examinations like: UCVA-BCVA-slit lamp examination, topography were performed preoperatively and 1, 3, 6, 12 and 18 months after the procedure. Results: The mean UCVA was 0.54±0.37 LogMAR preoperatively that changed to 0.41±0.33, 0.42±o.33 and 0.5±0.36 LogMAR in 6, 12 and18 months postoperation respectively (p=0.011). Mean simk was 43.49±3.72 preoperatively and changed to 42.68± 3.75, 42.62± 3.8 and42.78± 3.84 in 6, 12 and 18 months postoperative respectively. Conclusion: Crosslinking seems to be a safe procedure for stabilizing the progression of ectasia with stabilizing and improvement of UCVA and k-readings
