Adopting a multidiagnostic method for characterising the anterior segmentA multidiagnostic device is able to provide consistent measurements of refraction and ocular aberrations in healthy eyes. The consistency of refractive measurements is not dependent on the magnitude of the refractive error, with the same precision ability for moderate to high myopia and for hyperopia.
