Righton Objective

Retinomax 3 and Speedy-"i" series, the representation product of Righton Instruments
Retinomax Series, the world's leading handheld Ref and Refract Keratometer, delivers wide measurement range on par with table type Ref, now boasts greater mobility, stability and accuracy. The Retinomax 3 series is widely used as a global standard device for pediatric, screening, medical care in remote areas, disaster area and wide range of ophthalmic scene.
Current informatical society, eye fatigue, one of the typical modern diseases cause by eye accommodation issue is now easily discover by Speedy-"i" series during screening basis. Accommodative Micro Fluctuation result will show in graph for easy reading, plus opacity detection function makes Speedy-"i" the world first All-in-one Refractometer.

Handheld Auto Refractometer Retinomax 3 (Only Ref Reading)

Compact, light weight wireless handheld Refractometer
With just 969g (equipped with battery), it is 11.1% lighter than previous Retinomax 2. The center of gravity is design in the grip handle make it even much comfortable to hold.
Wide measurement range and high accuracy
Not only best used on infant or small children, but with the wide measurement range on par with table type Ref, it is suitable on most of the usage with high performance and accuracy result.
Speedy Measurement. Display. Printout
Fast measurement which takes only 0.14 sec. Pupil size will automatically measure, display and print out. Measurement is made five times, if the data is unstable, system will automatically retry for 3 times to achieve the most stable result.
Longer usage time
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.
Fixation intensity is automatically lowered for small pupil (less than 3mm)
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 will automatically reduced by approximately 45% to avoid pupil contraction.

New Generation of ALL IN ONE system with Auto Refractor, Keratometer, Auto Find (Opaque Media) and Accommodative Micro Fluctuation | Speedy-"i" K-Model (Keratometer) Speedy-"i"  (Refractometer only)

3 in 1 Function
With combination of Refractometer (Keratometer), Accommodative Micro Fluctuation, Opaque Media (opacity) screening, the measurement speed is vastly improved to only 49 sec (one eye).
Reduce of accommodation testing time
Measurement speed increased 20% compare with previous model. With the new SCR (Screening) mode, an eye can be tested in just 49 seconds.
Objectively find the cause of eye fatigue
Patient's individual AMF (Accommodative Micro Fluctuation) value will be analyzed and from the data, High Frequency Components (1 – 2.3Hz) will be extracted and based on measurement data, chart location, accommodation reaction value and pupil size to formulate FK map (Frequency of Kinetic reaction).
ADD Function
The ADD function enable a patient's near point power to be measured objectively by applying accommodative stimulation. And auto AMF can detects if the power gives the patient eye strain or not by color indication.
Residual Astigmatism Calculation (Only for K-model)
Residual astigmatism calculation, necessary for CYL contact lenses and CYL IOL prescriptions, is automatically conducted and results printed out (K-Model).
Astigmatism corresponding meridian target
By adopting a new fireworks chart, patient with astigmatism are able to focus on either one of the lines.
RX-4チャート
i-File software (options)
Data can be managed by using i-File and view saved record using Internet Explorer
