Ocular health and road safety in older adults
Joanne Wood PhD, DSc(hon), MCOptom, FAAO, FARVO, Centre for Vision and Eye Research, Optometry and Vision Science, Queensland University of Technology, Brisbane,
Professor Joanne Wood is from the Centre for Vision and Eye Research, Optometry and Vision Science, Queensland University of Technology, Brisbane, Australia. Joanne has an international reputation for her research which focuses on the impact of vision impairment and ageing on functional outcomes which has made a significant contribution to understanding how vision impairment affects driving performance, identifying risk factors for unsafe older drivers and on the factors affecting pedestrian and cyclist visibility at night-time.
Most countries set visual standards for driving eligibility, with visual acuity and visual fields being the most common worldwide. However, there is considerable debate regarding which aspects of visual function are most important for safe driving, the level of visual function at which driving performance and safety are impaired and how ageing and different eye diseases and vision impairments impact upon driving performance and safety. This presentation will provide a current and comprehensive overview of the current literature in the area and discuss the implications for optometrists assessing and managing patients with respect to driving and providing relevant advice.
Myopia Control And Optical Defocus - From Laboratory Research To Clinical Study
Visiting Chair Professor of Experimental Optometry
School of Optometry, The Hong Kong Polytechnic University
Professor Chi-ho To obtained his degree in Optometry from The Hong Kong Polytechnic and later earned his PhD from the University of Wales, College of Cardiff, United Kingdom. Upon returning to The Hong Kong Polytechnic, he began his academic career as a Lecturer and subsequently advanced to Chair Professor of Experimental Optometry. He currently serves as Visiting Chair Professor of Experimental Optometry at The Hong Kong Polytechnic University and is the Founding Director and Senior Advisor of the Centre for Vision and Eye Research (CEVR) at the Hong Kong Science Park.
Professor To’s research focuses on elucidating the pathogenesis and underlying mechanisms of myopia and glaucoma. He is a co-inventor of both the Defocus Incorporated Soft Contact (DISC) lens and the Defocus Incorporated Multiple Segments (DIMS) lens, two landmark innovations in myopia control. The DISC lens was awarded the Grand Prize and Gold Medal with Jury’s Commendation at the 39th International Exhibition of Inventions of Geneva in 2011. The DIMS lens received the Grand Prize, Grand Award, and Gold Medal, along with the Congratulations of the Jury, at the 46th International Exhibition in 2018.
Professor To has received a number of accolades, including the InnoStars Award (Hong Kong, 2021) and the Woodruff Distinguished Lecture Award from the University of Waterloo (2023). He was also named Outstanding Alumnus of the School, Faculty, and The Hong Kong Polytechnic University in 2023. His patented defocus lens technology has had a global impact, benefiting millions of individuals with myopia in more than 30 countries worldwide.
Eye growth is a visually guided process, and optical defocus has been shown to influence eye growth in young animals. Our research team attempted to examine whether optical defocus can also modulate human eye growth. As a proof-of-concept study, we incorporated myopic defocus in a special contact lens (Defocus Incorporated Soft Contact Lens – DISC) and conducted a myopia control clinical study with young children in Hong Kong. The results showed that DISC can significantly retard myopic eye growth in these children.
We went on to develop the first specialty ophthalmic lenses with optical defocus (Defocus Incorporated Multiple Segments, DIMS) and showed that it also effectively slowed down eye growth clinically by around 60%. Since then, a number of myopia control ophthalmic lenses using optical defocus have been introduced, which also showed significant and sustained myopia control effects.
There were also attempts to combine defocus treatment with atropine or red-light therapy, which have yielded additive control effects. While optical myopic defocus is accepted as an effective method for controlling clinical myopia, how the retina decodes the defocus remains unclear and awaits further investigations.
Good news! Contact lens wear is intrinsically inflammatory
DSc PhD BScOptom FAAO(Dip CCLRT) FCCLSA FACO
Nathan Efron is currently Emeritus Professor in the School of Optometry and Vision Science at the Queensland University of Technology; Editor of the journal Clinical and Experimental Optometry; and Immediate Past-President of the International Society for Contact Lens Research. He lectures extensively world-wide, particularly in the field of the ocular response to contact lens wear, and has published over 1,100 papers and has written/edited 7 books that have been published in a total of 24 editions and foreign translations.
Professor Efron has won numerous international awards, including being made a Companion of the Order of Australia, which is Australia’s highest civilian honour, for contributions to optometry and vision science.
Eyecare practitioners typically associate the notion of ocular inflammation during contact lens wear with serious complications such as microbial keratitis. However, more subtle mechanisms may be at play. In this presentation, Professor Efron will try and answer a question that has haunted him throughout his career – Is contact lens wear intrinsically inflammatory? The answer this question is approached by testing whether uncomplicated contact lens wear meets the clinical definition of inflammation (heat, redness, swelling, pain and loss of function) and the sub-clinical definition of inflammation (cytological changes and inflammatory mediator release). It is demonstrated that all of these criteria are met, meaning that contact lens wear is indeed inflammatory. And now for the good news: consideration of both classical and contemporary thinking about the role of inflammation in the human body leads to the perhaps surprising conclusion that the chronic, subclinical inflammatory status of the anterior eye (“parainflammation”) during contact lens wear is a positive phenomenon that reflects an upregulation of the immune system, in a non-damaging way, so that it is in a state of ‘heightened alert’, ready to ward off any extrinsic noxious challenge. The clinical implications of parainflammation are discussed.
Optometric Challenges in Refractive Surgery
Vice Dean of the Eye Hospital of Wenzhou Medical University, Director of the National Engineering Research Center of Ophthalmology & Optometry, Wenzhou Medical University
MD, OD, Professor, Chief Physician, PhD Supervisor, Inaugural National Outstanding Young Physician Awardee, Visiting Scholar of Bascom Palmer Eye Institute (University of Miami). Graduated from the New England College of Optometry, USA. Vice Dean of the Eye Hospital, Wenzhou Medical University. Director of the National Engineering Research Center of Ophthalmology & Optometry, Wenzhou Medical University.
Specialized in refractive surgeries for myopia, hyperopia, astigmatism, presbyopia, and other complex refractive errors, having treated tens of thousands of patients. Lead over 20 national and provincial research projects, published more than 100 papers, and contributed to over 20 textbooks and academic works.
Refractive surgery has become an important approach for correcting myopia and improving visual quality, yet optimal postoperative outcomes do not depend solely on the surgical procedure itself. Achieving stable and high-quality visual results requires incorporating optometry throughout the entire perioperative period.
Preoperatively, comprehensive optometric examinations and standardized refraction provide the foundation for defining treatment targets, assessing risks, and developing individualized plans. Intraoperatively, precise centration and optimized parameter selection help minimize the induction of higher-order aberrations, thereby improving functional vision. Postoperatively, continuous attention should be given to changes in accommodative status, with timely identification and management of undercorrection/overcorrection and refractive regression.

Developmental dyslexia is a specific learning disability characterized by persistent difficulties in accurate and/or fluent word recognition and decoding abilities. As one of the most common neurodevelopmental disorders (7.1% globally), developmental dyslexia can have lifelong impacts on academic achievement and self-esteem if not properly identified and supported. Phonological awareness deficits have long been proposed as the core cause of developmental dyslexia. However, recent studies indicate that the etiology is more multifaceted, involving a complex interplay of cognitive and sensory processing challenges. Among these, vision-related anomalies have been extensively studied. Recently, the visual magnocellular deficit hypothesis posits that dysfunction in the pathway responsible for processing rapid visual and temporal information contributes to reading difficulties. This presentation will discuss the current understanding of developmental dyslexia, provide an update on associated vision-related problems, and explore the critical role of optometry in the multidisciplinary assessment and management of this complex developmental issue.
