Standard graphs are a set of basic graphs which are almost mandatory when presenting refractive surgery outcomes or write scientific papers. Most journals like JRS (Journal of Refractive Surgery) or JCRS (Journal of Cataract and Refractive Surgery) will require these graphs to be part of the publication: Stability, Predictability, Safety, Efficacy.
See the JRS editorial which is included on our installation media: Standardized Graphs and Terms for Refractive Surgery Results; G.O.Waring III and D. Reinstein.
