 Our Founder - Alexander Dybbs, PhD.

Dear Customers,

For almost 40 years Sonogage has been a pioneer in ultrasound pachymetry. Founded by Alexander Dybbs PhD., a professor at Case Western at the time; Sonogage revolutionized the field with its 50 MHz probe and unparalleled precision. Since then thousands of customers have purchased Sonogage pachymeters and millions of patients have had their corneas measured with our technology.

Sadly, with the untimely passing of Alex, we have made the difficult decision to close the company at the end of 2023. We know that many of you are still using our pachymeters and we are proud that many are still operational after 10 to 20 years (or more). If your instrument needs repair, we would recommend contacting the following authorized 3rd party repair service (not affiliated with Sonogage):

Thank you for your many years of loyalty and patronage! It has truly been an honor to serve you and your patients.
