Purpose: To determine whether symptoms of dizziness and fall rates change due to
routine cataract surgery and to determine the influence of visual and refractive
factors on these common problems in older adults.
Methods: Self-reported dizziness and falls were determined in 287 subjects (mean
age of 76.5±6.3 years, 55% females) before and after routine cataract surgery for
the first (81, 28%), second (109, 38%) and both eyes (97, 34%). Six-month falls rates
were determined using self-reported retrospective data. Dizziness was determined
using the short-form of the Dizziness Handicap Inventory.
Results: The number of patients with dizziness reduced significantly after cataract
surgery (52% vs. 38%; χ2 = 19.14 , p<0.001), but the reduction in number of patients
who fell in the 6-months post surgery was not significant (23% vs. 20%; χ2= 0.87,
p=0.35). Multivariate logistic regression analyses found significant links between
post-operative falls and change in spectacle type (increased risk if switched into
multifocal spectacles). Post-operative dizziness was associated with changes in best
eye visual acuity and changes in oblique astigmatic correction.
Conclusions: Dizziness is significantly reduced by cataract surgery and this is linked
with improvements in best eye visual acuity, although changes in oblique astigmatic
correction increased dizziness. The lack of improvement in falls rate may be
associated with switching into multifocal spectacle wear after surgery. / The Dunhill Medical Trust
