Six PolyU Researchers Named Top 200 Scholars in Optometry Hong Kong the Most Impactful Region in Asia

Date: 11 Mar 2021

Six PolyU scholars have been ranked Top 200 globally in optometry research as revealed in a recently launched ranking system.

Six colleagues of the School, including Prof. Pauline Cho, Prof. Maurice Yap, Chair Professor of Optometry and K.B. Woo Family Professor in Optometry, Prof. Chi-ho To, Chair Professor of Experimental Optometry, Henry G. Leong Professor in Elderly Vision Health and Head of School, Prof. Marion Edwards, Former Head of School, Prof. Carly Lam and Dr Andrew Lam, Associate Head and Associate Professor, have been ranked as Top 200 optometry researchers globally. Specifically, Prof. Cho and Prof. Yap are on the list of the Top 100 optometry researchers. The results show the international academia's recognition of PolyU optometry researchers' contributions, particularly in myopia control, diabetic retinopathy, cornea biometry, etc.

According to the hCO-index that ranked countries and regions by the Top 200 scholars affiliated with, Hong Kong ranked first in Asia and No. 6 globally, following after the US, Australia, the UK, Canada and Spain. For institutions ranked according to the hIN-index of the Top 200 affiliated with, PolyU ranked No. 16 among the 72 eligible institutions.

Four vision science researchers developed this ranking system to recognize and honour optometrists worldwide who lead the profession through published research and establish a global standard for individual excellence in optometric research publications. The system automatically retrieves data from the Scopus database daily to keep the rank up-to-date. The ranking factors include h-index, number of publications, years of active publications, and number of citations.

The first-of-its-type ranking system in optometry research uses an algorithm that analyses publication metrics and is tailored to enable global universities, researchers, and academics to profile their research capabilities and their research impact.
