Marco RT-700 Minus Cylinder Illuminated Phoropter/ Phoroptor – Used

Description

What’s Included

• Marco RT-700 minus cylinder illuminated phoropter
• Power cable (as photographed)
• 90-day Digital Eye Center warranty

Condition & Warranty

Used. Tested before listing — sphere/cylinder/axis dials verified across full range, prism dial verified, lens turret confirmed clean, internal mechanism serviced (lenses cleaned, buttons lubricated). Note: the illumination function is unknown — the seller did not have the power cable available to test the illuminated reading scales, so we cannot confirm whether the illumination works. The unit is sold as a Marco RT-700 phoropter with the understanding that the illumination may or may not be functional. Mechanical refraction functions are confirmed working. Covered by a 90-day warranty on parts and workmanship.

Marco RT-700 — Used Minus Cylinder Illuminated Phoropter

The Marco RT-700 is Marco’s flagship illuminated minus-cylinder phoropter — the standard refraction instrument used in countless US optometry practices. This used marco rt-700 ships ready as a complete refraction station for any standard exam-lane stand, with internally illuminated reading scales for low-light exam rooms.

The RT-700 features a full sphere range of -19.00 D to +16.75 D in 0.25 D steps, a minus cylinder range of 0.00 to -8.00 D in 0.25 D steps, and a 0–180° axis dial in 1° increments. Built-in cross cylinders, prism, retinoscopy and Maddox rod accessories cover the full clinical refraction workflow — same precision-machined platform Marco built its US distribution business on.

According to a National Library of Medicine-indexed study (J Cataract Refract Surg, 2021), agreement between subjective phoropter refraction and objective autorefraction depends heavily on operator-instrument interaction — the precision-machined 0.25 D steps and clearly-illuminated reading scales the RT-700 was built to provide.

Why Practices Choose the Marco RT-700

• Internally illuminated reading scales — readable in dim exam rooms without separate room lighting; a key feature for modern darker exam-lane setups.
• Minus cylinder design — the dispensary convention used in most US optometry practices.
• Sphere -19 D to +16.75 D in 0.25 D steps — full clinical refraction range.
• Cylinder 0 to -8 D in 0.25 D steps — covers virtually all astigmatic prescriptions.
• Axis 0–180° in 1° steps — precise axis adjustment for fine astigmatism work.
• Built-in cross cylinder — for axis and power refinement during JCC technique.
• Built-in prism, Maddox rod, retinoscope lenses — full refraction workflow without external attachments.
• Marco service network — long-established US ophthalmic equipment distributor with extensive parts/service support.

Clinical Applications

• Subjective refraction — primary refraction workflow in chair-based exam.
• JCC astigmatism refinement — built-in cross cylinder for axis and power adjustment.
• Phoria and tropia evaluation — built-in prism and Maddox rod.
• Pediatric refraction — 1° axis steps allow precise adjustment in young patients.
• Pre-surgical refraction — illuminated scales reduce reading errors at low ambient light.

Who This Is For

• Optometry and general ophthalmology practices wanting an illuminated minus-cylinder phoropter at a sub-$2.5K used price point.
• Multi-doctor groups standardizing on Marco across refraction stations.
• Practices replacing an aging non-illuminated phoropter with an illuminated upgrade.
• Buyers in dim exam rooms where readable scales matter more than brand preference.
