خلاصه	The Low Vision Quality of Life Questionnaire (LVQOL) is a comprehensive instrument designed to measure the multidimensional impact of significant vision loss on health-related quality of life in individuals with low vision. Developed by Wolffsohn and Cochrane (2000), the LVQOL incorporates functional, emotional, social, and psychological domains and emphasizes measurement of disability and coping in populations with moderate-to-severe vision impairment where adaptive rehabilitation is the primary intervention.	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.
