Autorefractor Keratometer
Topcon KR-8900

Autorefractor Keratometer Topcon KR-8900The All-New Autorefractor Keratometer Topcon KR-8900 is loaded with new features with proven consistent and accurate results.

The new KR-8900 represents Topcon's latest generation of automated refraction technology. The KR-8900 maintains Topcon's core accuracy by utilizing our standard rotary prism technology, while adding on new features, such as a drop and close feature on the printer and an enhanced overall design for better patient interaction.

Key Features
- Rotary Prism measurement for enhanced accuracy
- Refractive and keratometric measurements through pupils as small as 2mm!
- New compact, stylish design saves space and enhances patient interaction
- Easy-to-read color LCD display
- Auto fire mode for fast, reliable data collection
- Seamless connection to other Topcon instruments
- Built-in printer

SIMULTANEOUS DISPLAY OF BINOCULAR READINGS
The new color LCD monitor simultaneously displays the readings of both right and left eyes so that the operator can instantly observe all of the pertinent information.
WIDER MEASUREMENT RANGE
The new series' wider range allows measurements to be obtained on patients with up to ±10D of astigmatism
TOPCON'S ROTARY PRISM MEASUREMENT SYSTEM
The new 8900 series features TOPCON's exclusive Rotary Prism Technology for unmatched accuracy and reliability. The off-centered ring target is able to measure areas that may be occluded by a small diameter pupil. The prism angle enables a much wider area of the retina to be measured. As a result, the measurement image provides extremely reliable data.
FASTER MEASUREMENT
The 8900 series are among the fastest auto refractors in the world. A specially designed CPU enables the 8900 series to significantly reduce the measurement time.
SCENIC FIXATION CHART
The scenic color chart makes eye fixation easier and is adjustable in two brightness levels for optimal measuring results with either large or small pupils.
AUTO MEASUREMENT
As soon as the Autorefractor Keratometer Topcon KR-8900 is properly aligned, this innovative function initiates the measurement process and completes three readings of each eye providing that proper alignment is maintained.
CORNEA DIAMETER MEASUREMENT
Corneal diameter can be measured either during testing of the patient or later by recalling the image of the cornea on the monitor of the Autorefractor Keratometer Topcon KR-8900
