Effectiveness of a Multi-disciplinary Vision Rehabilitation Program for Adults with Visual Impairment
Official title: Effectiveness of a Multi-disciplinary Vision Rehabilitation Programme in Improving Function and Quality of Life of Visually Impaired Patients: a Randomized Controlled Trial
Run by The Hong Kong Polytechnic University · NCT07827040 · Data updated 2026-11-12
We’re testing whether a multi-disciplinary vision rehab program helps adults with vision loss more than standard rehab or waiting.

Is this trial a fit for you?
✓Likely a good fit
Adults aged 18–80 with diagnosed low vision living in Hong Kong, Cantonese-speaking, smartphone owners, not currently in another vision rehab program, and willing to commit 6–12 months.
✕Probably not a fit
Individuals with severe cognitive or hearing impairment, unstable ocular/neurological conditions, or those residing in care facilities may see limited or no benefit.

What this trial studies
This randomized controlled trial compares three approaches to vision rehabilitation for adults with visual impairment: waitlist control, standard low-vision training, and a multidisciplinary program that adds further components. Participants complete baseline eye, cognitive, hearing, mobility, balance, and home-environment assessments before randomization. The eight-week intervention includes four on-site sessions, with all groups receiving low-vision training on advanced assistive technology; the multidisciplinary arm adds additional services. The study aims to measure changes in overall quality of life and functional outcomes over time, with follow-up to assess longer-term effects.
Why it matters
Potential benefit: If successful, participants may experience greater improvements in daily functioning and quality of life related to vision loss.
How similar studies have gone: Previous vision rehabilitation studies suggest that structured training plus assistive technology can improve function, but results for multi-disciplinary programs are variable and context-specific.
