The VX 90 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.
Refraction
Measure the refraction of the eye by indicating sphere, cylinder and axis
Keratometry
Measure the central and peripheral keratometry
backlighting
Be aware of the presence of cataracts by using backlighting for internal opacity detection
