Corneal Ectasia

This randomized study compares 2 variations of corneal crosslinking for treatment of keratoconus or corneal ectasia.

Measuring quality of vision and quality of life outcomes using a validated questionnaire in participants undergoing CTAK surgery for corneal ectasia

To evaluate the safety and effectiveness of the PXL Platinum 330 system for performing corneal cross-linking (CXL) for the treatment of ectatic disorders.

The purpose of this study is long-term follow up of patients with corneal diseases to analyze the quality of surgical interventions and diagnosis. Corneal ectasia, especially keratoconus, is a corneal disease that leads to an irreversible loss of visual acuity while the cornea becomes steeper, thinner and irregular. For these patients, surgical intervention (e.g. corneal cross-linking) is performed, in case of disease progression. Overall, a long-term follow up is needed to evaluate an early disease progression as well as corneal stability after surgical intervention.
