HOYA Vision Care, a leader in optical technology  innovation, took part in the 4th World Congress of Optometry (WCO4) on 8–10 September  2023 in Melbourne, Australia. This year’s WCO4, hosted in partnership with O=MEGA23,  was a prime opportunity for Eye Care Professionals from across the globe to participate in  high quality learning and professional development.  

As a proud Diamond sponsor of the WCO, and part of its commitment to share scientific  knowledge and professional insights, HOYA Vision Care hosted a symposium “Lighting the  way: new evidence and advances in myopia management”, where leading experts shared  recent research findings in the childhood myopia management space. The symposium was  chaired by Dr. Jagrut Lallu, Optometrist from Hamilton, New Zealand.  

Previous studies conducted by Professor Carly Lam and her team demonstrated the benefits  of MiYOSMART spectacle lenses use in children living in Hong Kong.1 HOYA Vision Care conducted research to explore whether the results translated to children living in Europe.  Professor Kathryn Saunders presented the outcomes from a recent 12-month observational study conducted in the UK, which showed that MiYOSMART spectacle lenses significantly  reduced myopia progression and axial elongation in UK children, and concluded that the  changes in spherical refractive error and axial length growth in European children were  comparable with those in Asian children.2 

With continuing interest and emerging evidence about protective effects of outdoor time and  daylight on myopia progression in children,3–7 Dr. May Zhang, Global Head of Professional  Affairs at HOYA Vision Care, educated the audience on the researched benefits and risks  associated with light exposure on myopic eyes and introduced the new MiYOSMART  Chameleon and MiYOSMART Sunbird sun spectacle lenses, which provide protection from  intense sunlight, while simultaneously slowing down myopia progression using D.I.M.S.  Technology.8–14 Dr. Zhang also shared the early experience with MiYOSMART sun  solutions, which showed at its early stage that almost 80% of children adapted to the new  spectacle lenses within a few hours.

At the end of the symposium, Dr. Soojin Nam, Optometrist from Hillsdale, Australia, spoke  about MiYOSMART solutions in clinical practice and shared case studies from her vast experience in the field of myopia management, showing that every patient has unique visual  needs that could be addressed with customized treatment. 

New evidence was also presented in the plenary program and in the posters’ session. Dr. Jagrut Lallu had presented the effectiveness of MiYOSMART and related combination  treatment strategy in slowing down myopia progression among multi-ethnic patients in New  Zealand.15 Dr. Joanna Przeździecka-Dołyk presented the outcomes of myopia controlling  procedures in young adults with early-onset progressive myopia in regard to the refractive or  axial main course of the refraction error, which showed better results in slowing axial  elongation using optical methods, rather than pharmacological interventions.16 To conclude, Dr. Oliver Woo presented real-world evidence on the use of MiYOSMART spectacle lenses in Australian children of Chinese descent, showing yet another instance of satisfactory  treatment and myopia slowing effect.17 

Since its launch in 2018 through the end of 2022, over four million MiYOSMART spectacle  lenses have been purchased by parents across the world.18 With the launch of the new  MiYOSMART Chameleon and MiYOSMART Sunbird spectacle lenses, HOYA Vision Care  will continue to help fight and control the growing problem of myopia around the world.
