Weighing just under one kilogram, the main body with battery is over 17% lighter for the K-plus 3 and 11% lighter for the Retinomax 3 than the conventional Retinomax Series models. The Retinomax Series 3’s center of gravity is in the grip, making the Series 3 feel much more lighter and balanced.
If no measurement is made within six seconds, the unit automatically enters Quick mode. Measurement is then taken in 0.07 seconds. In Auto Quick mode, “AQ” appears on printouts.
The unit measures pupil size automatically, displays the X (horizontal) size on the monitor, and prints out the XY (horizontal and vertical) sizes separately.
Results can be used in checking accommodation, mydriasis, ADIE and Horner-associated syndromes.
Inclination Of Main Body And Displays Value
Levelness is detected digitally with the use of the unit’s parallel sensor. It is displayed on the monitor in every 2° pitch up to ±12°, and every 3° pitch up to ±45°.
With the adoption of a lithium ion battery, continuous operational time has been extended to approximately 80 minutes. The station has an AC adapter, allowing it to be connected to the main body with a DC cord (optional) to enable extended continuous operation. This facilitates screening, as well as use in an operating room.
The minimum pupil measurement size in Auto Quick mode is 2.3 mm. If a pupil is less than 3.0 mm, the fixation target intensity is automatically reduced by approximately 45% to avoid pupil constriction. The intensity can also be reduced with the fixation intensity key.
The diopter adjustment range has been extended to -18 -- +23.
Data from the last measurement is automatically saved after the Retinomax 3 is turned off. The last patient data can be recalled by pressing the PRINT key. The data can be transferred wirelessly to a printer.
The Retinomax 3 includes the retro illumination mode for observation of the media opacities.
In the Refraction/Keratometry Mode, readings up until both data are indicated require only 0.25 seconds -- 0.15 seconds for Keratometry and 0.12 for Refractions.
Tangential peripheral readings are possible, as is E-value printing.
When the eye is exposed to bright light, the pupil contracts, often making measurements impossible. Within the K-plus 2, the minimum required pupil diameter is only 2.5 mm plus the intensity of the fixation target is variable.
