I suffered with a rare condition called SJS and could not find a provider who knew as much as Dr. Yiu did. He was like no Dr. I have ever seen, he handled me with so much care, and I finally felt like I was getting the right care after 9 weeks of intense anxiety and suffering. I'm so grateful.

It was an honor and privilege to be able to see a premier ophthalmologist, such as Dr. Yiu. I had the opportunity to have cataract surgery in a facility closer to my home in Washington DC, but I wanted the best possible care which I received at Johns Hopkins Wilmer Eye Institute.

At the end of my appt, he asked if he could pray for me. If I could've cried, I would have. It's been a very long time since I've had a doctor feel like they are genuinely concerned about my health.
