Visionix VX 90

Autorefractor / Keratometer with auto fog system

The VX 90 provides autorefraction and keratometry data that is accurate, reliable, and essential for contact lens fitting. A moving fixation target with auto fogging allows for minimal accommodation.

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
