Biography Dr Andrew Lam graduated from the then Hong Kong Polytechnic with a Professional Diploma in Optometry. After working in a private optometric practice for two years, he returned to the then Hong Kong Polytechnic working as a Research Assistant and later obtained his Masters and PhD degrees from the Department of Optometry, University of Bradford, in the UK. He is now the Programme Leader of the?Bachelor of Science in Optometry Programme at the School of Optometry, PolyU. He was a recipient of the Department's Teaching Excellence Award in 2002 and also 2008.
Dr Lam is a Fellow of the American Academy of Optometry. He is Chairperson of the Preliminary Investigation Committee and the Registration Committee of the Optometrists Board of Hong Kong. He has also served as Chairperson in various Committees of the Optometrists Board of Hong Kong, including Education Committee and Examination Committee. He was Treasurer of the Hong Kong Society of Professional Optometrists from 1993 to 1998.




Research Overview Knowledge of corneal biomechanics is important for understanding the development of myopia. Weakened corneal biomechanics may indicate an overall weakened outer ocular coat, hence an eye that is more prone to axial elongation when it is exposed to myopigenic factors. High myopia is also associated with glaucoma, where intraocular pressure (IOP) measurement is important in its diagnosis.
Research in corneal biomechanics could help us to better understand the development of myopia. Understanding the influence of corneal biomechanics in IOP measurement may eventually shift the paradigm of glaucoma diagnosis and treatment.
Development of myopia and glaucoma may share similar pathophysiology of a weakened outer ocular coat. Since high IOP is a risk factor of glaucoma, current medical and surgical treatments in glaucoma target reducing the IOP. The Gold standard for IOP measurement is through corneal touch. Alteration of corneal biomechanics such as after corneal refractive surgeries in myopes can affect accuracy of IOP measurement.
