There are 2 arms in this study. one control arm - High astigmats that choose an aspheric ioL and astigmatic spectacles to clear the near and distant images, anD the High astigmatic ioL arm group that inserts the high astigmatism ioL at surgery requiring no spectacles after surgery most likely. Both arms further determine efficacy of the Toric high cylinder ioL by patient subjective questionnaires at the beginning and end of study and objective visual outcome testing as in standard of care when patient comes for pre and post operative assessments.
