This KR-8000 autorefractor/keratometer is a demo unit for doctors' offices. It is in excellent condition because only lightly used during the demo period. Cosmetically and functionally it is looking and working as new. Comes with everything that came with it...e.g. Topcon kit, spare fuses and Manual. If you're in need of an accurate, easy to use, and patient friendly autorefractor but do not want to break the bank or settled for a refurbished unit, this is the ideal machine to own.
