Our Story

An endeavour towards quality at-home healthcare

Born from Stanford-inspired BioDesign Innovation course at the University of Melbourne, Vysum was founded by passionate graduates in 2022. The team interviewed and surveyed 500 patients and clinicians and identified a major gap in ophthalmic care: the low compliance rate for ophthalmic treatment and the lack of patient progress data to clinicians.  

Working with engineers, clinicians and patients, the team at Vysum is developing an EyeCare device for better treatment delivery and mangement. They endeavour to provide quality at-home healthcare and empower users with digital health technologies.
