About this study

Official title: Randomised Controlled Falls Prevention Trial of Plain Distance Glasses in Elderly Multifocal Wearers.

The purpose of this study is to determine whether the provision of supplementary plain distance glasses for outdoor use to older users multifocal glasses will reduce falls rates over a 12 month period.

Read the detailed description

Background: Bi-, tri- and multi- focal ('multifocal') glasses have been associated with increased rates of falls in older people (Lord et al 2002).

Study Aim: To determine whether the provision of supplementary plain distance glasses for outdoor use to older users multifocal glasses will reduce falls rates over a 12 month period.

Study Design: A randomised controlled assessor-blinded trial with two parallel groups in 580 participants. Study inclusion criteria are: outdoor use of multifocal glasses 3 or more times per week, community-dwelling persons aged 65+ years with a recent fall OR persons aged 80+ years regardless of falls history, Folstein Mini Mental score of 24+, and adequate visual contrast sensitivity (Melbourne Edge Test score of 16+dB). All participants will receive an optometry assessment and updated multifocal glasses (if required) at baseline. Intervention group subjects will receive a pair of plain distance glasses and counselling for their use in predominantly outdoor situations. Control group participants will use their multifocal glasses in their usual manner. Falls rates and compliance with the intervention will be recorded on monthly falls diaries returned by the participants.
