תקציר	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 GQL-15 is a 15-item, disease-specific quality of life questionnaire designed to measure the impact of glaucoma on patients' daily functioning and psychological well-being. Developed by Nelson, Aspinall, and colleagues in the UK (1998), the GQL-15 emphasizes glaucoma-specific concerns—visual field loss, peripheral vision, lighting sensitivity, and falls risk—making it a sensitive complement to generic or broader vision-related instruments in glaucoma populations.
