Fattori genetici ed ambientali nel Cheratocono

Highlights •The posterior corneal curvature after scleral lens wearing has never been studied. •A flattening curvature appears in nasal quadrant in intracorneal ring patients and in inferior hemisphere in keratoconus. •The cornea is slightly thinner after scleral lens wear except...

Abstract Purpose To evaluate the differences in corneo-scleral topographic profile between healthy and keratoconus eyes, and their potential diagnostic ability for keratoconus detection. Methods Prospective comparative study including 21 keratoconic eyes (11 patients) and 88 healthy eyes (88 patients). In...

SIGNIFICANCE This study showed an improvement in three-dimensional depth perception of subjects with bilateral and unilateral keratoconus with rigid gas-permeable (RGP) contact lens wear, relative to spectacles. This novel information will aid clinicians to consider RGP contact lenses as a management...
