Accurate refraction measurement

Large pupil zone imaging method

The large pupil zone imaging method enables the measurement of wider area refraction up to 6 mm diameter and can indicate the difference between the wide area refraction and central area refraction of up to 3.5 mm diameter.

 

SLD and highly sensitive CCD

The system, which combines the super luminescent diode (SLD) and highly sensitive CCD, significantly improves measurement capability even in dense cataractous eyes.

 

Optimal fogging to minimize accommodation

Fogging allows the patient to view the target clearly and minimizes the interference with accommodation even in high astigmatism.

Easy VA measurement with glare test

The ARK-1s and AR-1s provide visual acuity (VA) measurement. A glare source is illuminated beside the chart and the glare VA can be measured.

 

 

Simulated patient’s vision of VA chart and glare source

 

Vision with glare and halo

Normal vision
Simple opacity assessment with retroillumination image

The retroillumination image enables the observation of opacity of the optical media of the eye.

 

Eye with dense opacity

Eye with light opacity
Patient-friendly accommodation measurement
Objective measurement of accommodation is performed with the patient focusing on a target that moves from distance to near.

 

Keratometry measurement with mire ring
The mire ring is used to measure keratometry. It reduces eyelid artifacts.
