Summary Different calculation modalities for pseudophakic and phakic toric lens implants are discussed: what are the benefits and drawbacks of formula‐based and raytracing techniques? How could we set‐up our own calculation sheet in a standard PC software package? A step‐by‐step calculation is shown in a clinical example. When do we need customized software? How can we evaluate residual refractive error after axis displacement of the toric lens implant? A list of commercial and non‐commercial online calculators for toric lenses is shown.
