Used Phoropter for Sale — Burton 7500-I AutoCross Illuminated Minus Cylinder
This used phoropter for sale is a Burton 7500-I AutoCross refractor in the minus cylinder configuration preferred by most optometrists. The 7500-I was designed around illuminated dials, so sphere, cylinder and axis readings stay legible with the room lights dimmed for refraction. Burton’s AutoCross mechanism keeps the cross-cylinder aligned with the cylinder axis as you rotate it, which speeds up astigmatism refinement. With a sphere range of +16.75 D to -19.00 D and cylinder to -6.00 D, this used phoropter covers the prescriptions seen in a typical primary care lane.
A study in Clinical and Experimental Optometry (National Library of Medicine) evaluated an automated binocular phoropter against conventional subjective refraction, the reference method that a manual refractor like the Burton 7500-I performs every day. For practices that want a dependable manual lane at a fraction of new-equipment cost, a serviced used phoropter remains a practical choice.
Why Practices Choose the Burton 7500-I
- Illuminated dials — lit power and axis scales are easy to read in a darkened exam room, reducing reading errors during the refraction.
- AutoCross cross-cylinder — the cross-cylinder follows the cylinder axis automatically, so axis and power refinement take fewer manual adjustments.
- Minus cylinder convention — matches the prescription format most optometric practices write, with no transposition at the dispensing step.
- Wide sphere range — +16.75 D to -19.00 D handles high myopes and hyperopes without trial lenses.
- Cylinder to -6.00 D — extendable to -8.00 D with the auxiliary cylinder lens for high astigmatism.
- Serviced before shipping — every lens cleaned and controls lubricated, so the unit arrives clean and smooth to operate.
- Standard refractor arm mounting — fits the refractor arm on most ophthalmic stands for a straightforward lane swap.
Clinical Applications
- Routine subjective refraction: sphere determination, cross-cylinder astigmatism refinement and binocular balance.
- Near add determination for presbyopic patients.
- Confirming or refining autorefractor readings before writing a spectacle prescription.
- Contact lens over-refraction during fittings and follow-up visits.
- High-power refractions within the +16.75 D to -19.00 D sphere range.
Who This Is For
- Optometry practices opening an additional refraction lane on a limited budget.
- Practices replacing a worn phoropter with a serviced manual unit.
- Teaching clinics and residency programs training students on manual refraction.
- New practices outfitting exam rooms with reliable manual equipment.
