Purpose: The aim of this study was to delineate the personality traits of patients affected by keratoconus (KC) compared with a group of nonkeratoconic controls matched in age and sex.
Methods: In this prospective interventional case-control study, 60 consecutive subjects (30 KC cases and 30 healthy controls), aged 18 to 30, were enrolled at the time of their first encounter at the ophthalmology unit of the Fondazione Policlinico "Tor Vergata", Roma. After completing the ophthalmic evaluation, participants were asked to respond to the National Eye Institute Visual Function Questionnaire-25 (NEI VFQ-25).
