Portable phoria tester

The WUQ Optical Phoria Tester is a handheld ophthalmic instrument designed for eye-care professionals who need to measure horizontal and vertical phoria. It combines a rotating prism assembly with a Maddox rod in a single portable unit for clinical or field use.

20 prism dioptre range

The rotating prism provides an inspection range of 20 prism dioptres, giving sufficient headroom for routine convergent and divergent measurements. Larger deviations beyond this limit will require a different instrument or supplementary prisms.

Replaces separate prism bars

This tool consolidates a prism bar and Maddox rod into one device, reducing the kit a clinician carries for cover-test workflows. The jump is worthwhile when a compact, single-handed instrument speeds up near and distance testing without sacrificing the 20 dioptre measurement span.

Questions about this item

Does the 20-prism rotating Maddox rod work with standard ophthalmic trial frames or does it require a dedicated mount?

The instrument is hand-held; you grip the handle and place the rod frame against one eye while the other eye views the target directly, so no trial-frame mount is needed.

How can I confirm the 20-prism scale is calibrated correctly after I zero the index reticle to the "0" mark on the reading ring?

After zeroing, view a point light source 3-5 metres away; if the red streak bisects the spot when the handwheel reads zero, the scale is tracking correctly.

What comes in the package and what must I supply myself for the first test?

The tester itself is included; you must provide a point light source such as an ordinary flashlight positioned 3-5 metres away.
