Lectures

Plenary Lecture at the Santen Vision Summit in Bangkok, Thailand, January 2020. "Bacterial Ocular Infection in Asia: A Physician's Journey"

In this video, Dr Cordelia Chan speaks on eye infections, with special emphasis on bacterial infections of the eye. She talks about how the management of bacterial keratitis in Asia has changed over the years, and covers the problem of the overuse of antibiotic eye drops and antibiotic resistance. This talk chronicles Dr Chan's journey as a subspecialist in Cornea and External Eye Disease, from her days as a young eye doctor in Singapore in the early 1990s, to the present. 

Patients who have had a painful red eye in the past, with conjunctivitis or a corneal ulcer from contact lens wear, may find this video of interest.

To SMILE or not to SMILE?

Small incision lenticule extraction (SMILE) is one of the laser vision correction procedures for short-sightedness (myopia) and astigmatism available in Singapore and around the world. Dr Cordelia Chan was one of the first surgeons in Singapore to perform SMILE in 2012. In this talk she gives her views on the procedure, and shares her experience with both ReLEx SMILE and LASIK. So is SMILE better than LASIK? Watch the video to find out.

Website On Eye Rubbing

This is an important website on Keratoconus and Eye Rubbing for both patients and ophthalmologists.

The website was created to highlight the deleterious effects of eye rubbing on the cornea, and to link it to keratoconus genesis and progression in an evidence-based manner. 

This website was designed and created by the ophthalmologists of the Rothschild Foundation, Paris, France, with Dr Cordelia Chan as the Special Editing Consultant. 

If you have keratoconus, high astigmatism, or have a habit of rubbing your eyes, this website is for you. It also gives useful tips on how to avoid eye rubbing and provides alternatives and less harmful techniques of eye rubbing for those who really feel the need to touch their eyes.
