Abstract

Three corneal topography systems were used to measure six different PMMA manufactured surfaces. Inter-system accuracy was analyzed by comparing the average of three measurements per surface to the known central curve. On average, the Humphrey MasterVue system read the surfaces as being steeper than the known value and the EyeSys system read the surfaces as being flatter than the known value. The Oculus system also measured the surfaces slightly steeper but was the most accurate overall. In conclusion, as far as refractive surgery comanagement would be concerned, it would be advisable to maintain patient topography readings using your own instrumentation rather than relying on the other doctor's data to avoid the problem associated with different values from different systems.
