Brief Summary
Falls are the most serious and frequent home accident amongst elderly. Most falls occur during walking. Vision is reduced with ageing and visual impairments affect balance. Uncorrected visual deficits and balance problems are reported to be risk factors for falls and fall related fractures. The present project uses a longitudinal design and aims at assessing the impact of cataract surgery on balance and gait as risk factors for falls.
