WAM-5500 Binocular Accommodation Auto Ref/Keratometer


Dynamic Accommodation Measurement with Binocular View

NEW  A.M.MODE – Automatic Accommodation Calculaion

Until now, when you are measuring the accommodation, you had to printout at each distance after the measurements and make the calculation by yourself.  However, with this new function, you DO NOT need to printout at each distance NOR make the calculation by yourself.  Instead, you just need to printout after all the measurements are taken and the accommodation result is already there for you.

Easier measurement of IOL patient

The accuracy of the measurement is improved for IOL patient by eliminating unnecessary reflection from the IOL.

Easier access to the eye ground image

A freeze image function displays the eye ground image to check the reason of non-measurement and confirm the good or bad measurement.



It measures 6 times per second to check the accommodation response dynamically.

WAM-5500 High Speed
●Example ; 33 years old male
This is the data of moving the Near Point Card every 20 seconds.With this data, the subject eyes are accommodating from the ideal value of -2.00D to -5.00D. Additionally, the pupil diameter is constricting from 4.0mm to 3.2mm. (Blinking at the same interval.)

Error handling mechanism during the Hi Speed Mode is improved

Up till now, the measurement could not be taken for a few? seconds after the patient blinks and the difference would be too big compare to the previous ones. With the improved algorithm, it would judge the blink and move to the next measurement immediately without losing the data for a few seconds.

Measurement with Both Eyes

With both eyes open, the natural condition, the measurement is taken. Thus, there would be less Instrumental Myopia, and allows you to achieve more precise measurement.

Easy Measurement with Open View Window

The Open View Window, which adopted the Half Mirror, makes it possible to take a measurement without the subject being aware as there is no distraction of view. For the infant/children, it gives less pressure, and you can measure easily and quickly. Addi-tionally, it allows you to go through the measurement process smoothly since you can observe the condition of a subject directly.

Any Target

Unlike regular refractometer, you can choose any target interested to the subject and set to any distance.

Indication of SE (Spherical Equivalent)

The change of accommodation in SE can be confirmed easily on the LCD.

Easy Over-Refraction Measurement

Since it is adopting the Open View Window, you can measure a subject with glasses and contact lens as well as a subject with the IOL, easily. It also allows you to confirm the prescription.WAM-5500 binocular
