Very negligent doctor and didn't warn her patient about the side effects of her medicine and keep prescribing the same thing. She kept on prescribing steroid applied medication for my skin for 7 years and she never once told me that it would thin my skin out. After so many years, the steroid did damage and made my skin peel off, becoming so thin that you can see the veins in my body on the part applied. While this Dr. Khoo may be polite, she isn't professional in the sense she kept prescribing medicine, didn't warn of the side effects and she didn't find alternative to treat the patient. She was also on her phone a lot instead of consulting her patient when her patients are waiting for long time (hours) outside her clinic. Wouldn't recommend this doctor at all !
