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
