สรุป	The VF-14 is a 14-item, disease-specific functional status questionnaire developed to measure visual disability from cataract and its response to cataract surgery. Created by Steinberg, Tielsch, and colleagues (1994), the VF-14 focuses on difficulty with 14 common daily activities (e.g., reading small print, driving day/night, recognizing faces) and is used primarily to assess cataract severity, prioritize surgery, and document post-operative improvement in functional vision.	The OSDI is a 12-item symptom questionnaire designed to screen for and grade the severity of dry eye disease and other ocular surface disorders. Developed by Schiffman, Christianson, and colleagues (2000), it quantifies patient-reported ocular irritation and visual function limitations across frequency and impact domains. The OSDI is the most widely used screening tool for dry eye in clinical practice, clinical trials, and epidemiological studies worldwide.
