Fourier Transform of Videokeratography Data: Clinical Usefulness in Moderate and Frome Fruste Keratoconus
NCT02617368 · Status: COMPLETED · Type: OBSERVATIONAL · Enrollment: 185
Last updated 2015-12-01
Summary
Primary objective of this study was evaluate the diagnostic capacity of fourier analysis of keratometric data in differentiating moderate KC and FFK from healthy corneas.
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.
