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 eye…

New paper: Modeling refractive correction strategies in keratoconus

It is challenging to find the optimal spectacle correction for a keratoconic eye. To assess this problem in detail, the SyntEys KTC model was fitted all possible spherocylindrical corrections within the range of a phoropter, each time determining the visual image quality. This demonstrated that the…

New paper: Scleral asymmetry as a potential predictor for scleral lens compression

This study shows that scleral asymmetry can be used as a parameter to predict scleral lens settling. Larger amounts of scleral asymmetry were found to lead to larger decentration in the impression of the lens on the ocular surface, as well as deeper compression of the sclera. Scleral asymmetry has…

New paper: Anterior eye surface changes following miniscleral contact lens wear

The prescription of scleral contact lenses, as well as the number of practitioners who fit scleral contact lenses, has notably increased over the last few years. The purpose of this work was to quantify the effect of short-term miniscleral contact lens wear on the anterior eye surface of healthy ey…
