This prospective study included 99 patients (117 eyes) with progressive keratectasia who underwent standard crosslinking. At 12 months the complication rate was 2.9 percent; failure rate, 7.6 percent. The authors identified age and preoperative visual acuity as significant risk factors for complications, and a high preoperative maximum keratometry (K) reading as a risk factor for failure. They conclude that a preoperative maximum K reading less than 58.00 diopters may reduce the failure rate to less than 3 percent, and restricting patient age to younger than 35 years may reduce the complication rate to 1 percent.
