Refractive surgical outcomes may be tracked and evaluated by collecting information such as the following:
whether there are overcorrections or undercorrections, and whether they occur more often with longer eyes or shorter eyes or roughly equally in both
whether the incision routinely induces cylinder
whether toric lenses are correcting as calculated
whether limbal relaxing incisions have been effective for the correction of astigmatism
Commercially available programs may be useful for tracking outcomes. After the surgeon has analyzed these factors, he or she may make adjustments to improve refractive outcomes, such as including a “surgeon factor” (a modification of the parameters used that reflects the surgeon’s experience) in some lens power calculations, changing the calculation software, or using immersion or optical biometry. Improving outcomes is important for increasing not only patient satisfaction but also surgeon confidence.
