We defined the progression of corneal ectasia over the preceding 12 months as the following criteria.
1. an increase of at least 1.00 diopter (D) in the steepest keratometry
2. an increase of at least 1.00 D in the manifest refraction and manifest refractive spherical equivalent
- a degradation
3. an decrease of at least 0.1 mm in base curve of hard contact lens
Key exclusion criteria
1. Thinnest corneal thickness < 300 micron
2. Present medication of Psoralen
3. History of photodermatosis
4. History of epilepsy
5. History of fluorescein induced allergy
6. Cases with possibly undergoing keratoplasty during the observation period
7. Cases considered as inappropriate by physicians
8. Cases offering the stop of the treatment
