Ms Wai Siene Ng has been taking good care of my wife’s severe glaucoma condition for several years and hopefully will continue to do so. She has a wonderful manner that inspires hope and confidence that she will continue to pull more rabbits out of the hat that will preserve my wife’s sight to the extent that is possible. We are both very happy with the service.
