Professor Lisa Keay is the Head of School at the School of Optometry and Vision Science, UNSW Sydney and an Honorary Professorial Fellow at The George Institute for Global Health, UNSW Sydney. She is a public health researcher, with expertise in epidemiology, health promotion and injury prevention. She trained as an Optometrist, has a PhD and MPH from UNSW Sydney and completed a research fellowship at the Dana Center for Preventive Ophthalmology, Johns Hopkins University. In her career she has worked in Australia, United States and United Kingdom. She leads a large and successful program of public health research in vision and eye health spanning injury prevention, healthy ageing, health systems research and implementation science. She leads research in safe mobility for older drivers and devotes considerable efforts to translation of her research into policy and practice. Recommendations arising from her fall prevention research include timely cataract surgery, best practice refractive management and evidence-based exercise programs to reduce risk of falls for older people with vision impairment, who are excluded from community falls prevention programs. She was a commissioner for the 2020 Lancet Commission of Global Eye Health, on the topics of associations between vision impairment and road traffic injury and falls. Her health systems research includes evaluations of new models of care for chronic eye diseases and refractive error in high- and low-income settings.
