Professor Lisa Keay is Head of the School of Optometry and Vision Science and an Honorary Professorial Fellow at The George Institute for Global Health. She has developed links with government, community organisations and other stakeholders to identify key, policy-relevant research questions and to answer them with high quality research. Her research tackles the two major causes of injury to older people: falls and road traffic injuries. Her work in road safety led to an ARC funded evaluation of a program to promote safe mobility for older drivers in 2014 with 4-year follow-up in 2017. Her NHMRC funded trial evaluating targeted falls prevention for older people with vision impairment and blindness is in progress and new work is planned evaluating expedited cataract surgery and integrated refractive management to prevent falls in the larger number of older people with cataract. She has acted in formal advisory roles to government agencies, regularly engages with the media and has held executive roles in peak bodies to translate her research into policy and practice. Innovative strategies are being comprehensively evaluated which stand to prevent injury and make a difference to the lives of many older Australians.
