NCT00218894
First received: September 20, 2005

  Purpose
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.

Study Completion Date: December 2009
Primary Completion Date: March 2008 (Final data collection date for primary outcome measure)
Groups/Cohorts Assigned Interventions
post cataract surgery Procedure: Cataract surgery
surgery one one or two eyes by use of two different types of lenses and correcting for refraction

Detailed Description:
A longitudinal design is used, where subjects referred to the Cataract Unit are tested 1-3 weeks in advance of the surgery, and 4-6 weeks and 12 months after the surgery. Outcome measures are visual function, falls, balance and gait. Secondary outcome is quality of life, fear of falling and daily life functioning
