For patients with prior radial keratotomy (RK), cataract surgery has to be done differently. These eyes also often have significant astigmatism that can be addressed at the time of the cataract surgery. When evaluating these corneas, we need to determine the degree of symmetry as well as if the astigmatism is regular or irregular. In this case, the central cornea had symmetric, regular astigmatism that was nicely addressed with a toric IOL.
