contraindications might include scarred corena, keratoconus, active infection, history of herpes simplex, astigmatism less than 1 diopter or large amounts, or a patient that didn't want the procedure.

I believe that thin corneas are a contraindication. Another possibility for correcting astigmatism is a toric IOL. With your degree of astigmatism, one study showed that this option eliminated slightly more astigmatism than LRIs.
