KR-9900 / RM-9900 Auto Refractometer Auto Ref/keratometer
The new double zone control design makes the fogging process and the measurement process independent of each other: fogging first then the measurement, which makes the human eye fully relaxed before measurement, helping capture the true diopter of the human eye and improve the accuracy of the measurement result.
Adopts new refraction measurement technique, providing more comprehensive image analysis and more reliable and consistant measurement data.
Mire ring double-ring measurement
The two rings facilitate synchronous focusing and measurement, helping get more measurable points to enhance the accuracy of keratometry measurement.
Rotation prism
Rotation prism can equalize the light source to get more evenly distributed measure ring and enhance the quality of the projected rings so that the measurement result consistency is improved.
Super luminescent diode (SLD) +high sensitivity CCDprism
Compared to common LED light source, using SLD can get more clear image. Even though the reflected light from fundus is weak, the high sensitivity CCD can still capture the ring shaped image, enabling the device to measure for cataract and be suitable for wider patient groups.
Automatic human eye tracing
The automatic human eye tracing and focusing (Y direction) technique makes the deivce lock on the pupil center fast and accelerate the measurement process.
Pupil and Cornea( White to white)
Diameter measurement Measurement of Pupil size enables the operator to check refraction in different environment conditions such as Scotopic, Mesopic and Photopic.Also, White to White measurement is helpful in certain IOL calculation formuia which is needed for cataract surgery
Peripheral keratometry measurement
Centered on the 3mm area around the corneal center to measure the steepness of peripheral cornea to get the thorough understanding of the cornea status.
RETRO
Using RETRO measurement to briefly evaluate the opacity of the anterior segment.
Tiltable Touch Screen
7.0in touch screen with 90° titlable angle: operator can get comfortable view whether sitting or standing.
Printer With Auto Paper cut
Built-in high speed thermal printer: auto paper cutting, printer paper replacing is easy and prints fast.
Motorized Chin Rest
Motorized chin rest and head rest: for smooth height adjust and easy operation.
One Touch Lock
Unit lock button: one push to lock the measuring unit on the device chassis.
