He is very knowledgeable and answered all my questions patiently. He is also very helpful in explaining issues that I want clarified about my particular eye condition. Will be glad to refer friends and family to him should the occasion come.

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!

Dr Johnson has been responsible for proteting my vision for 15 years. My eyes have been subject to neovascular proliferation for 30 years, and most recently to age-related dry glaucoma. His care has been comprehensive and compassionate. He discusses my problems and care with me in straightforward and clear terms. I depend on him without reservations.
