Multifocal Spectacle and Monovision Treatment of Presbyopia and Falls in the Elderly.

Abstract

Presbyopia is an age-related condition that affects approximately 1.8 billion people worldwide. Strategies to correct presbyopia include both nonsurgical and surgical approaches. Although eye care providers assume that multifocal spectacles and monovision have lower risks than surgical interventions, there is evidence to suggest that the use of these nonsurgical approaches in the older population increases the risk for trips and falls. Each year, fall-related injuries and deaths are reported in a substantial portion of the population, both globally and in the United States. Previous studies have shown a link between visual acuity, contrast sensitivity, stereoacuity, and visual field impairments and falls. More recent mechanistic and epidemiological studies have shown that multifocal spectacles and monovision can increase the risk for falls as well. Although evidence on the financial burden of falls related to multifocal spectacles or monovision is limited, total direct medical costs related to falls associated with multifocal spectacles are estimated to be approximately $11 billion annually in the United States. Therefore, it is important that eye care providers consider the risk for falls associated with multifocal spectacles and monovision when making decisions on the best strategy for correcting presbyopia in older adults.
