Cohorts for the Three Autorefractors and Two Age Groups with Compared Prevalence of Disease and the Referral Rates Influenced by Choice of Specific, Sensitive or Medium Instrument Referral Criteria (IRC). For Each Device and Age, The Refractive Subcomponents Hyperopia, Anisometropia, Cylinder and Myopia the Medium Cut-off is Given with Sensitive and Specific Option Cut-Offs in Parenthesis.
