Prof. Kee is a Professor teaching Optometry subjects related to clinical and ophthalmic dispensing at the School of Optometry, The Hong Kong Polytechnic University. He received his Bachelor degree in Optometry from the Hong Kong Polytechnic University. He later obtained his Masters and PhD degrees from the City College of New York and University of Houston, respectively. Before returning to Hong Kong, Prof. Kee was an Assistant Professor in Physiological Optics at the New England College of Optometry in Boston, Massachusetts, USA.

Research Overview

My constant research interest is how visual optics regulate eye growth. Through active collaborations with vision scientists and engineers around the world, we have devised ocular diagnostic tools and animal models to study the role of visual experience on refractive development. Knowledge gained from the mixture of basic and translational research has accelerated our knowledge transfer.

In particular, the transformation of a digital diagnostic imaging device to analyze anterior eye shape from our animal lab has facilitated early diagnosis of astigmatic children. Our current goal is to understand how optics due to abnormal corneal shape can alter refractive development.
