Description
What’s Included
- Marco RT-700 minus cylinder illuminated phoropter (used)
- 90-day Digital Eye Center warranty
The metal stand holding the phoropter in the photos is not included.
Condition & Warranty
Used. This unit has been checked and its refractive functions are working well; it shows some signs of use, visible in the photos. Before shipping, every lens is individually cleaned and the dial buttons are lubricated, which may add a short delay to shipment. The built-in lights have not been tested because no power cable came with the unit — the illumination may or may not work, and the buyer is responsible for obtaining the correct power cable to test it. Covered by a 90-day warranty on parts and workmanship; the illumination is excluded from the warranty.
Marco RT-700 Phoropter — Used Minus Cylinder Refractor
The Marco RT-700 phoropter is a manual, minus-cylinder refractor from Marco’s illuminated line, built for fast, repeatable subjective refraction in optometry and ophthalmology lanes. This used Marco RT-700 phoropter covers sphere from +16.75 D to −19.00 D and cylinder to −6.00 D (−8.00 D with the auxiliary lens), with a cross cylinder synchronized to the cylinder axis and a 0–20Δ rotary prism. Its auxiliary dial puts the retinoscopic lens, Maddox rods, red/green lenses, polarizing lens, pinhole and occluder one click away, so the whole refraction stays in the instrument.
Clinician-guided refraction still matters: a 2026 study in the Journal of Optometry quantified the professional’s impact on subjective refraction outcomes compared with self-driven testing (National Library of Medicine, PMID 41771238).
Why Practices Choose the Marco RT-700

- Minus cylinder format — the standard configuration for most US refraction lanes and training programs
- Full sphere range — +16.75 D to −19.00 D in 0.25 D steps handles high myopes and hyperopes without trial lenses
- Synchronized cross cylinder — the ±0.25 D cross cylinder follows the cylinder axis for quicker axis and power refinement
- Rotary prism 0–20Δ — measure phorias and prism needs directly in the head, in 1Δ steps
- Complete auxiliary dial — retinoscopic lens, white and red Maddox rods, red/green lenses, polarizing lens, +0.12 D sphere, pinhole and occluder
- Illuminated scales — the RT-700 design lights its scales for reading in a dim exam room (untested on this unit)
- PD 48–75 mm — 1 mm adjustment fits the large majority of adult patients
Clinical Applications
- Subjective refraction for spectacle prescriptions
- Retinoscopy through the built-in retinoscopic lens
- Binocular balance with red/green lenses and polarizing filters
- Phoria and prism assessment with the Maddox rods and rotary prism
- Pre-operative and post-operative refraction for cataract and refractive surgery patients
Who This Is For
- Optometry practices adding or replacing a minus-cylinder lane
- Ophthalmology clinics that need a dependable manual refractor in exam or tech rooms
- Optometry schools and residencies teaching manual refraction
- Satellite and mobile clinics looking for a budget-friendly manual phoropter
