Four instruments, one complete picture
Ocura uses the same questionnaires found in clinical research and ophthalmology practice. Each one captures a different dimension of how dry eye may affect your life.
Ocular Surface Disease Index
The gold standard 12-question assessment for dry eye symptoms and their impact on daily activities.
Dry Eye-related Quality of life Score
Measures how dry eye symptoms may affect your quality of life and daily routines.
Patient Health Questionnaire
Screens for mood and emotional well-being, which research suggests may be associated with dry eye severity.
Computer Vision Syndrome Questionnaire
Evaluates how screen time and digital device use may contribute to eye discomfort.
Why these instruments?
Every questionnaire in Ocura is a published, peer-reviewed clinical instrument used in ophthalmology research and practice. They are not proprietary scoring systems — they are the same tools eye care professionals use to evaluate dry eye disease.
