” My vision was not right for almost 1 year–saw my previous eye doctor who found nothing unusual.  My friend referred me to Dr. Chan & Dr. Chong for a second opinion.  I presume my eyeglass power needed updating.  After doing a few specific tests, I was sent to get neurological & endocrine tests to rule out a brain problem on an emergency.  Turns out that WAS the culprit which affected my eyesight.  Now, what a relif the issue is being taken care of and I got my vision back!”  –S.L. *

” Just want to thank Dr. Chong for advising me to go to ER at Toronto Western with a detailed written report after our exam.  According to the specialist there, she is 1 in 10 who took extra time & care to do a thorough exam hence detected part of my retina has detached, which saved my vision before i was too late.  I was not even aware of anything wrong prior to my visit with her !”  –T.M.*
