Clinical utility of ocular residual astigmatism and topographic disparity vector indexes in subclinical and clinical keratoconus

Graefe's Archive for Clinical and Experimental Ophthalmology, 2015
We aimed to characterize the distribution of the vector parameters ocular residual astigmatism (ORA) and topography disparity (TD) in a sample of clinical and subclinical keratoconus eyes, and to evaluate their diagnostic value to discriminate between these conditions and healthy corneas.This study comprised a total of 43 keratoconic eyes (27 patients,

Effects of Ocular Residual Astigmatism on Refractive Outcomes for Myopia Correction After Keratorefractive Lenticule Extraction Surgery

Journal of Refractive Surgery
Purpose To evaluate the effects of ocular residual astigmatism (ORA) on refractive outcomes for patients with astigmatism after keratorefractive lenticule extraction (KLEx) and to identify the ratio of the ORA/manifest refractive cylinder at the corneal plane (MRC) resulting in a greater index of success (IOS).
