Visionix Speedy-K2

Speedy K2 Auto Refractometer Keratometer

Fast auto refractometry and keratometry

Speedy-K2 Autorefractor Keratometer provides accurate refraction and keratometry measurements in a compact design thanks to the retinoscopy measurement principle.
 

Automatic, quick measurement

ACV
ACV (Asymmetric Coefficient Value) is a numerical value used to show stability of light measurement. ACV 0 is most stable, larger value need to take caution. To reject unstable measured values caused by obstruction against measuring light such as eyelid, eyelashes, opacity and etc, ACV is useful as a guideline during REF measurement.

AUTO2 MEASUREMENT MODE
In addition to normal fogging, a more precise fogging method is possible by manually selecting A2 or preset under setting menu to automatically activate under specific conditions. This kind of fogging is useful for reading the eyes of patients with unstable eyes, instrumental myopia or other conditions.

AUTO PUPIL CENTER MODE
If ectopia pupillae or small pupil is detected, it will automatically activate pupil center mode to assist in taking stable REF measurement.
 

Simple and stable

ORIGINAL UNIQUE FIXATION SYSTEM
The light intensity can be changed with 3 steps. The unique fireworks picture chart enables astigmatism patients to focus on any of the meridian lines so that the patient can follow the picture. Pupil size is measured during a refraction reading, dropping light intensity automatically when the pupil diameter is smaller than 3mm.

RETRO ILLUMINATION MODE
When measurement is unstable, opaque media such as cataracts can be detected using the monitor.

LCD WITH 45-DEGREE TILT FOR FREE MEASUREMENT POSTURE
The LCD touch monitor can be tilted (0-45 degrees) allowing the examiner to conduct measurements from a standing or seated position.

“OPEN EYELID” DETECTION
Automatically detects obstruction at pupil area, like eyelid or eyelashes, during measurement.
