Welcome to the ASSORT TORIC Calculator.

This online calculator allows the use of any type of toric intraocular lenses (IOL) commercially available.

Features of the ASSORT TORIC calculator include:

  • Calculation of the Spherical Equivalent IOL using SRK/T, Holladay or Hoffer Q formulae.
  • Effective Lens Position (ELP) using A-constant, Surgeon Factor (SF) or pACD.
  • Spherical power of implant is factored into calculation of toric power of IOL at corneal plane.
  • Simple comprehension of calculations and display of required vectors.
  • Postoperative mathematical analyses for magnitude and axis of toric implant with refractive surprises.

Look for the ASSORT ICL and Corneal Astigmatism Analysis Calculators coming in the near future.
