This paper evaluates the repeatability of refraction in keratoconus patients and normal myopes, using representations of spherocylindrical power that are theoretically valid. Data consist of test–retest refraction data from the Collaborative Longitudinal Evaluation of Keratoconus (CLEK) Study and si...
