PolyU professor named “Most Impactful Author” in orthokeratology

Prof Pauline Cho

Prof. Pauline Cho of the School of Optometry of PolyU has recently been named as the “Most Impactful Author” in a bibliometric analysis of the orthokeratology literature published in the UK Contact Lens & Anterior Eye Journal. The number of citations and the total number of publications of Prof. Cho’s work rank first among orthokeratology scholars in the world.

PolyU is also recognised as “The Leading Institution” with the highest number of highly-cited papers in the field. In addition, Dr Peggy Cheung, Postdoctoral Fellow of Prof. Cho’s team, ranks third in the world, in terms of the number of citations of her orthokeratology-related publications.

This recognition is a testament to the influential contributions made by Prof. Cho and her research team in the field of orthokeratology.


What is orthokeratology?

Orthokeratology, the use of flat-fitting conventional rigid gas permeable lenses for daytime wear, was first reported in the 1960s. The flat-fitting lenses resulted in changes to corneal curvatures, leading to a temporary correction of myopia, but their use was soon abandoned due to unpredictable results and undesirable side-effects. However, the treatment was revived in the early 2000s (modern orthokeratology) with the introduction of specially designed orthokeratology lenses, improved lens material (allowing overnight wear) and sophisticated equipment (allowing accurate monitoring of changes of the corneal surface).

In 2005, Prof. Pauline Cho and her team published the first longitudinal study on overnight orthokeratology, showing effective slowing of myopia progression. Since then, numerous publications have confirmed the myopia control effect and many practitioners have adopted this modality on a routine basis for myopia management.
