Currently the Chief Scientist and Innovation Officer at the Brien Holden Vision Institute Limited (BHVI), in addition to an appointment as a Conjoint Professor at the School of Optometry & Vision Science, UNSW, Arthur Ho is also a Voluntary Professor of Ophthalmology at the Miller’s School of Medicine, University of Miami, Miami, FL, USA, and Adjunct Professor of Biomedical Engineering at the Department of Biomedical Engineering, University of Miami, Coral Gables, FL, USA.

Arthur's early participation in the development of the first high-precision optical pachometer (the “Holden-Payor pachometer”) which paved the way to understanding the oxygen needs of the contact lens-wearing eye, developed in Arthur the philosophy that new scientific knowledge and discoveries are often facilitated by development of new technology. Thus he maintains a focus on the development of innovative devices and instrumentation for research. This emphasis on device and technology development sees Arthur named as an inventor on over 70 issued patents and additionally over 80 pending applications.  Arthur has published over 110 peer-reviewed articles and is an editor of 20 conference proceedings.

While his areas of interest in optometric research is broad, Arthur’s current research focus is in myopia and presbyopia and particularly in understanding the opto-mechanical characteristics of the accommodation system and developing vision correction systems for controlling myopia progression.
