I am so thankful I am under Dr. Johnson's care since 2012 and until these days.. Dr. Johnson is very kind, understanding, and thorough when he checks my eyes. He's the best surgeon in this field.

I have a patient for many years after he was able to save my retina in my left eye from total detachment. fortunately for my ophthalmologist's quick referral to see Dr Johnson, it was handled on an emergency basis, and all is great, and remains as such.
I've been under his care since then, seeing him yearly and couldn't be more fortunate under his care. An outstanding physician!
