According to recent clinical studies, current toric IOLs almost never rotate after their implantation. Nevertheless, we are in agreement with Drs. Berdahl and Hardten that the alignment of the axis is critical. Errors in positioning the IOL can occur and their effects are of interest, mainly for the future of multifo-cal toric IOL implantation.Although we have not had the opportunity to use the toric results analyzer, it seems an interesting and useful tool to solve clinical problems that unavoidably appear with the use of multifocal toric IOLs. Because the recipient of a multifocal IOL has high expectations for complete refractive error correction, he/she will not be satisfied if there is appreciable residual astigmatism.
