Dr Poemen Chan graduated from The University of Hong Kong with multiple scholarships and awards, including CP Fong Gold Medal in Medicine, H.C. Liu Prizes in Anatomy, Mr & Mrs S. H. Wong Foundation Scholarship, BL Wong Scholarships and Yu Chun Keung Mem. Scholarships. He was trained in Hong Kong Eye Hospital since 2007 and was promoted associated consultant in 2014. During his ophthalmology training, he granted the HC Ho Medical Education Foundation Scholarship for his overseas clinical visit in Moorfield’s Eye Hospital (London, UK) and Prism’s Eye Institute (Toronto, Canada). During the service, he received the Best Poster Display Award in the Hospital Authority Convention 2014, Outstanding Staff and Team Award in Hospital Authority Convention 2016 and The Best Service Provider award of Hong Kong Eye Hospital.

Dr Chan is currently the coordinator of the CUHK-HKEH-PWH International Fellowship Programme, the programme director of glaucoma surgery subspecialty for the CUHK Jockey Club Ophthalmic Microsurgical Training Programme and the Academic Coordinator of the glaucoma service of Hong Kong Eye Hospital. He serves as glaucoma subspecialty liaison for World Ophthalmology Congress (WOC) 2018, Secretary of glaucoma subspecialty for The 33rd Asia-Pacific Academy of Ophthalmology (APAO) Congress 2018 and as International Advisory Committee of The Association for Research in Vision and Ophthalmology- Asia (ARVO-Asia) in 2017.

Research Areas

  1. Ocular hypertension – risk assessment and cost effectiveness of treatment
  2. Cost-effectiveness analysis of glaucoma treatment
  3. New surgical techniques of glaucoma surgery
  4. Risk assessment of glaucoma
  5. Angle closure glaucoma and normal tension glaucoma
Glaucoma Subspecialty Liaison and Session Chairs World Ophthalmology Congress 2018 (Spain)
Coordinator/Secretary and Session Chairs (Glaucoma Subspecialty program) The 33rd Asia-Pacific Academy of Ophthalmology Congress 2018 (Hong Kong)
International Advisory Committee The Association for Research in Vision and Ophthalmology-Asia 2017 (Australia)

Research Programmes

  1. To development of a system of cost-effective treatment in Ophthalmology.
  2. To investigate the variability of risk estimation in glaucoma.
  3. To investigate the long term results of untreated ocular hypertension in Asian population.
  4. Development of a new surgical technique of conjunctival closure in trabeculectomy.

Results of Note

  1. Developed a safe, protocol-driven system of reducing medication use for patients with ocular hypertension
  2. Demonstrated that combined phacotrabeculectomy is more cost-effective than phacoemulsification alone for treating primary angle closure glaucoma
  3. Demonstrated the importance of medication cost and how this would affect the cost-effectiveness of treatment in primary angle closure glaucoma
  4. Demonstrated how different methods of assessing vertical cup-to-disc ratio could affect the risk assessment for untreated ocular hypertensive eyes and how such variability could affect treatment decision.
