Lensco-meter calibration system for standard keratometers.Also, Haag-Streit calibration device for Goldmann tonometers (and, yes, the tonometers do go out of spec!). Includes like-new prism also.
The Lensco-meter sells for around $180 and the tonometer prism for $150.
Both in absolute mint condition. I'm now retired and don't need to keep this stuff, so make me a reasonable offer! I had to put in a price to get the listing to be accepted.
