Dizziness, but not falls rate, improves after routine cataract surgery: the role of refractive and spectacle changes.

Purpose: To determine whether dizziness and falls rates change due to routine cataract surgery and to determine the influence of spectacle type and refractive factors.

Methods: Self-reported dizziness and falls were determined in 287 patients (mean age of 76.5 ± 6.

Effects of induced astigmatism on foot placement strategies when stepping onto a raised surface.

Purpose: Large changes in spectacle prescription can increase falls risk in older people. We investigated the effect of induced astigmatism (a common cause of distorted or blurred vision in older people) on locomotor stepping patterns to determine whether the orientation of astigmatic changes could have differential effects on gait safety when negotiating steps and stairs.

Methods: 10 older adults (mean age 76.
