Comparison of a Scheimpflug imaging with other screening indices in diagnosing keratoconus and keratoconus suspect

Scientific Reports
Keratoconus (KC) is an irreversible blinding eye disease; therefore, early screening of KC suspects (KCS) is crucial for protecting patients’ quality of life. Scheimpflug imaging is a commonly used screening device in clinical practice.
