Bill I see that that would be frustrating. The systems, as you know have different techniques, SCHEIMFLUG vs PLACIDO RINGS. Also different computations of variety of areas to arrive at their results. BUT that is why we use all of them sometimes. AND I wouldn't want to hear the sales team say "our measurements are an EXACT match or the same as our competitors." Good luck with your surgeon. As a side note the corneal thickness measured with PACMATE, CIRRUS and PENTACAM are not the exact same either.

After repeat telling him that they are not going to match exactly he states that each instrument should have a daily calibration check. He states the IOL master has a calibration check and the others also have checks.

The data is stored on a disc that would have been with the unit when delivered. I don't find any detailed info about calibration or confirming or verification. I'm curious as to why you're asking.
