Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Study participants were recruited from the Cornea Outpatient service in a consecutive if eligible basis. Two study groups were formed: a)KC group included patients those were diagnosed and classified for moderate keratoconus according to the Amsler-Krumeich classification system, b) FFK group (FFKG) that included patients diagnosed with FFK, and c) Control group (CG) was formed by refractive surgery candidates. Pentacam (Pentacam HR, Oculus Optikgerate GmbH, Heidelberg, Germany)measurements were performed by the same experienced operator in a consistent way.
