Study of Glasses to Improve Thinking and Quality of Life in Older Adults in India Randomized Trial of Free Near and Distance Spectacles to Reduce Cognitive Decline and Falls

What this Trial Is About

Researchers are evaluating whether providing free near and distance glasses to older adults in Hyderabad, India, aged 60 years and above, with under- or uncorrected vision problems can improve their quality of life and slow cognitive decline. This mixed-method study combines a randomized controlled trial RCT with a qualitative component to understand the cultural context and lived experiences of participants with reduced vision. The study also aims to assess the impact of vision correction on reducing falls, depression, social isolation, and physical activity over a period of 36 months. Participants are randomly assigned to one of two groups. Those in the intervention group receive free spectacles for near andor distance vision at the start of the study, with options to choose from 20 frames. They will have annual eye exams and refractions to adjust or replace glasses as needed. The control group receives prescriptions and free glasses only at the end of the study. Cataract surgery is provided at no cost for those recommended during follow-ups. Annual assessments continue for three years, including home visits for participants unable to attend clinic visits. During the study, participants undergo evaluations of cognitive function, quality of life, visual functioning, physical activity, depression, social interactions, cost of care, and number of falls. Researchers use various questionnaires and cognitive tests at baseline and every 12 months until 36 months. The study also tracks compliance with spectacle use and cataract surgery outcomes. Safety and follow-up data, including reasons for any loss to follow-up, are carefully recorded to support comprehensive analysis of the interventions effects.
