Visionix VX90

ARK with auto fog system

The VX90 is an ophthalmic diagnostic device with refraction and keratometry functionalities as well as accurate of cataracts. A moving fixation target with auto fogging allows the patient to fully desaccommodate in order to get the patient refraction in any conditions.

Measure the refraction of the eye by indicating sphere, cylinder and axis

Measure the keratometry: central and peripheral keratometry

Measure the pupil diameter

Be aware of the presence of cataracts by using backlighting for internal opacity detection
