Dr. Leung is very knowledgeable and also very easy to interact with. I have a lot of confidence in his assessment and would highly recommend him to others.
My experience overall GOOD!
I can't know if I would recommend him until I actually have the procedure done and see how it goes, and how he is during and after it. He uses a bit more scare tactics than I prefer. I would rather have someone be a bit more gentle in describing the problem and the possible outcomes. He is very dogmatic in his explanations, and frankly, scares me when he talks about it. This is Not my preference in a Doctor, particularly one who is going to be messing with my eyes!
told me about the things I needed to know to keep my symptoms at bay. Highly likely to recommend to others

Dr Leung is an excellent practitioner. He keeps me informed of everything regarding my case. I am shown eye scans (OCT scans) and given explanations of what I'm looking at. The step-by-step procedures are spelled out carefully. And my condition is stabilizing and improving because of Dr Leung's treatment and expertise. We make decisions together concerning my care. My confidence in Dr Leung is always 100%.
Finally after all of the eye problems that I have been having, Dr. Leung was finally able to start treatment.
Dr. Leung explained things in detail in a very clear way, and made sure all my questions were answered.
This is the first time I met Dr. Leung (I am Dr Moshfegi's patient and he was on leave). Dr Leung was kind enough to see me at short notice for my concerns of blurred vision and he took the time to listen to my concerns and thoroughly examined my eye.
