蔡雅君醫生於2006年畢業於香港大學內外全科醫學士學位,隨後在基督教聯合醫院(UCH)進行了眼科培訓。當她在UCH時,她是香港大學的榮譽導師,為母校的醫科學生教學做出貢獻。她於2013年7月加入了香港大學家庭,擔任眼科學系臨床助理教授,投入更多時間進行學術研究。自加入香港大學以來,她在各國際會議上發表了40多學術報告,其中包括受邀演講,並在國際學術期刊上發表了26篇學術文章。她已獲得超過200萬研究經費(作為主要申請人)進行學術研究,並改善對患者的治療。她的一些主要成就包括引入膠原交聯治療囊性泡漏和大泡性角膜病。我們是香港首家也是唯一一家提供這種治療的機構。她同時也是博士和碩士學生的導師。 除了向學生和其他專業醫學人員提供教育外,她還發表了各種公開會談和書面章節和報紙文章,以提高公眾對常見眼睛疾病的認識。她也是健康快車的訪問顧問醫生。她的許多研究都與其他學術單位合作,她歡迎來自不同專業人士的合作。此外,蔡醫生還到韓國首爾國立大學醫院,諾丁漢大學醫院和英國Moorfields眼科醫院等,學習並與國際專家交流她的研究。 蔡醫生積極參與各種臨床和動物研究,她的研究興趣在青光眼,視神經保護,眼前節疾病和兒童近視控制。

Dr Choy graduated from the University of Hong Kong with MBBS degree in 2006 and subsequently underwent Ophthalmology training at United Christian Hospital (UCH). She was an honorary tutor of the Faculty when she was at UCH where she could contribute to the teaching of the medical students of her alma matar. She rejoined HKU family in July 2013 as Clinical Assistant Professor at the Department of Ophthalmology to further her academic pursuit, where she can devote more time in researches. Since she joined the University, she has delivered more than 40 presentations in various regional and international conferences, including invited talks; and has published 26 articles in peer-reviewed international journals. She has obtained more than $2 million research funds as principal applicant to conduct researches and to enhance management of her patients. Some of the major achievements include the introduction of collagen crosslinking in treating cystic bleb leak and bullous keratopathy. We are the first and only institute in Hong Kong to apply such services. She has been supervisor for PhD and MPhil students. Apart from education to students and other healthcare professionals, she has also delivered various public talks and written book chapter and newspaper articles to improve public awareness to common ocular diseases. She is also the visiting consultant of Lifeline Express. Many of her studies are collaboration with other units, and she welcomes collaboration from different professionals. Furthermore, Dr Choy has attached to overseas institutes including Seoul National University Hospital, Nottingham University Hospital and Moorfields Eye Hospital, to learn and exchange her research ideas with international experts.

Research interest:

  • Novel diagnostic tool and treatment in glaucoma;
  • Neuroprotection in particular in relation to life-style modification
  • Anterior segment diseases
  • Myopia control in children
