AB  - PURPOSE OF REVIEW: To evaluate and summarize literature from the past 18 months
      reporting advancements and issues in astigmatism assessment prior to cataract
      surgery. RECENT FINDINGS: New and updated toric calculators and regression
      formulas offer the opportunity for more accurate lens selection for our patients.
      Concurrently, improvements in topographic evaluation of corneal keratometry have 
      allowed for a decrease in unplanned residual corneal astigmatism. Measuring
      posterior corneal astigmatism is especially valuable in eyes with keratoconus
      when planning to implant toric intraocular lens (IOL) and now allows access to
      this patient population. SUMMARY: Improved accuracy of astigmatism evaluation now
      occurs with point reflections on the corneal surface along with the latest
      generation toric lens formulas which integrated posterior corneal astigmatism,
      predicted lens position, and intended spherical power of the IOL. These
      improvements can allow for incorporation of toric lenses in keratoconus patients.
