Six scholars from PolyU’s School of Optometry have been listed among the world’s 200 most impactful optometry researchers, according to the “Global optometrist top 200 research ranking”. They are (in alphabetical order):


  • Professor Pauline Cho, Professor

  • Professor Marion Edwards, former Head

  • Dr Andrew Lam, Associate Head and Associate Professor

  • Professor Carly Lam, Professor

  • Professor To Chi-ho, Head and Chair Professor of Experimental Optometry, Henry G. Leong Professor in Elderly Vision Health

  • Professor Maurice Yap, Chair Professor of Optometry and K. B. Woo Family Professor in Optometry


Professor Pauline Cho and Professor Maurice Yap have been ranked among the world’s top 100 optometry researchers. The results recognise the important contribution PolyU’s optometry researchers have made to the field, particularly in the areas of myopia control, diabetic retinopathy and cornea biometry.


The ranking system recognises optometrists who lead the profession in published research, establishing a global standard for individual excellence in optometric research publications. The system retrieves data from the Scopus abstract and citation database on a daily basis to keep the ranking up to date. Ranking factors include the h-index, which analyses the impact of an author’s publications, their number of publications, years of active publications, and the number of citations they receive.


According to the system’s hIN-index, which ranks the institutions with which the 200 optometrists are affiliated, PolyU ranked 16th out of 72 eligible institutions. Meanwhile, the hCO-index, which ranks countries and regions in which the top 200 scholars work, ranked Hong Kong first in Asia and sixth globally, behind the US, Australia, the UK, Canada and Spain.


In addition to conducting impactful optometric research, PolyU is also Hong Kong’s sole provider of the Bachelor of Science (Hons) in Optometry Programme and the Doctor of Health Science (Optometry) Programme. The School of Optometry recently launched a Massive Open Online Course “How We See the World: Visual Function and Eye Health” on edX to increase the general public’s awareness and understanding of human vision and ocular health.
