Speedy, quiet and comfortable refraction
The compact DR-900 has a 40° field of view coverage and a
minimum spherical step-size of 0.12 dioptre.
The built-in IR enables communication with a digital test chart or
projector.
The head rest and face shields are constructed using soft
and light materials which are easily detachable to disinfect or clean. A breath
shield is available as an optional extra to enhance safe distancing measures
when manually adjusting the refractor head. The five meter cables allow for
increased distancing between the operator and the patient.
The incorporated double LED illumination is dimmable from
25%, 50%, 75% and 100% to suit various refraction room light conditions.
The DR-900 refractor head will automatically converge to the
appropriate near PD angle when the desired reading distance (30, 40, 50, 60
& 70 cm) is selected.
Simple and easy operation
The multi display interface design clearly divides the chart information, measurement information and import/ memory areas, making using the DR-900 intuitive and improving workflow and examination time.
The DR-900 has Jackson Cross Cylinder power of (±0.25D)
& (±0.50D) as well as Auto-Cross Cylinder (±0.25D).
The jog dial has a 2-in-1 function that enables the
practitioner to toggle the X-CYL function (XC1 or XC2) whilst the enter key
allows the practitioner the choice to [Select], [Adjust] or [Enter] function.
Cylinder/Axis is automatically changed according to patient's visual
preference. Spherical equivalent is automatically compensated whenever 0.50D
cylinder is changed during the JCC test.
The built-in thermal printer is conveniently located behind
the controller, with auto-cut function.
The touchscreen flexible tilt display (20° - 80°) enables
the user to operate in either sitting or standing positions.
Intuitive user interface
The DR-900 offers the Spatial Frequency Contrast sensitivity
test, which can be binocularly and monocularly examined. Ten contrast levels
are available at 5 levels of cycles per degree. The test results are shown in a
graph and can be exported and printed. *only available in combination with
Rexxam LCD-1000/1 000P.
A full set of pre-defined tests are available to perform any
kind of binocular examinations, such as phoria, convergence, accommodation,
etc.
The user can mask all available optotype charts (horizontal,
vertical & single letter). The mask will stay even when the user is
scrolling through different visual acuity charts. The optotype chart can be
randomly changed with a simple push of the touch screen. *only available in
combination with Rexxam LCD-1000/1 000P
The DR-900 includes an auxiliary set of supplementary
accessories including linear or circular polarisation filters, red or green
filters, Maddox_H and Maddox_V filters.
Compatibility and connectivity
The DR-900 can communicate with various other Rexxam
products including Auto-Refractors, Digital Lensmeters and Auto
Ref-Topographer, where data can be exported to the DR-900 automatically or
manually. With one touch of the DR-900 touch screen panel, data is instantly
sent to the refractor head. The save function enables the user to test or show
the patient's current or new prescription for confirmation. The DR-900 can also
communicate with the Rexxam LCD Chart or Chart Projector via the LCD touchscreen
control function.
