Dr Seiler diagnosed me with keratoconus over 20 years ago.Keratoconus is a progressive disease of the cornea which results in really,really bad astigmatism. There is no cure except an eventual cornea transplant but it can be managed if you find someone who is skilled in prescribing contacts and glasses for really challenging eye conditions. I was truly fortunate to find Dr Seiler who was never put off by the difficulties my situation presented. Instead, he is painstaking and amazingly skilled in giving me the best vision possible in a frequently changing and generally deteriorating eye condition. Dr Seiler is enthusiastic about what he does and is always up to date with the latest research and technologies concerning eye health and vision. I have been treated by specialist physicians over the years and I think it is significant that Dr Seiler was held in the highest regard by all of them. If you want to get the very best vision possible, while also protecting and maintaining the health of your eyes, I highly recommend Dr Seiler.
