概要	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 NEI-VFQ-25 is a 25-item self-report questionnaire measuring the impact of vision loss on health-related quality of life across multiple functional and psychological domains. Developed by the National Eye Institute (Mangione et al., 2001), it is the most widely used vision-specific QoL instrument in ophthalmology and serves as the gold standard for quantifying patient-reported visual disability across diverse eye conditions.
