Eligibility

Sex/Gender

All

Inclusion criteria

Inclusion criteria: Diagnosed as keratoconus, which requires keratoplasty

Exclusion criteria

Design outcomes

Primary

Measure	Time frame
Efficacy will be evaluated by visual acuity, refraction, corneal curvature, and corneal topography. Safety will be evaluated by assessing corneal endothelial cell count and frequency of other ocular complications.	—
