    The Topcon KR-800 Auto Kerato-Refractometer is compact and easy to use. It features Topcon’s Rotary Prism technology for highly accurate measurements and a simple, intuitive display. Also known as: KR800 and KR 800. 


    • Rotary Prism Technologyallows for unparalleled precision and reliability and measures a wider area of the retina while permitting measurements through pupils as small as 2mm in diameter
    • Bright, 8.5" color touch-screen display
    • Smooth operation of the unit when using the X-Y control lever and more fluid measuring process
    • Compact, modern, and ergonomic design
    • Improved joystick operation 
    • Ease of use and operability
    • EMR connectivity
