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.
