Clinical trials: Keratoconus
Keratoconus, Corneal Ectasia
Accelerated Corneal Collagen Crosslinking for Keratoconus and Ectasia Using Pulse or Continuous UV-A Light
Corneal collagen crosslinking has been demonstrated as an effective method of reducing progression of both keratoconus and post-refractive corneal ectasia, as well as decreasing the steepness of the cornea in these pathologies.

Keratoconus
Evaluation of Corneal Epithelial Mapping in Diagnosis of Early Keratoconus by Anterior Segment Optical Coherence Tomography
The cornea, as the outermost refractive structure of the eye, plays a critical role in maintaining clear vision. Its transparency and structural integrity are essential for optimal visual function.
