New paper: Assessing the visual image quality provided by refractive corrections during keratoconus progression

This works assesses the visual image quality of keratoconic eyes corrected by means of sphero-cylindrical spectacles and rigid contact lenses as keratoconus progresses. Overall, the results reflect the clinical experience that subjective refraction is challenging in highly-aberrated keratoconic eyes, the benefit of spectacle correction is short lived and that rigid contact lenses provide better and more stable visual image quality as the disease progresses. The model suggests the presence of a second focus in some cases, that remains to be confirmed clinically.
