Description
Marco Phoropter RT-700 Minus Cylinder Illuminated Used — Subjective Refraction Instrument
The Marco phoropter RT-700 is a fully illuminated minus-cylinder refraction instrument built for efficient, accurate subjective refractions in busy optometry and ophthalmology practices. This Marco phoropter features a built-in illumination system that enhances cross-cylinder visibility and lens clarity, supporting consistent results under varied exam-room lighting. As reviewed in a 2026 study on subjective refraction workflows (J Optom PMID 41771238), standardized phoropter-based refraction remains the cornerstone of clinical prescribing accuracy.
What’s Included
- Marco RT-700 illuminated phoropter (used)
- 90-day warranty
Note: The metal stand shown in product photos is not included with the purchase.
Why Practices Choose the Marco RT-700
- Illuminated optics — built-in illumination system for enhanced cross-cylinder clarity and reduced measurement variability in dim exam rooms
- Minus cylinder configuration — standard minus-cylinder format compatible with most modern refraction workflows and chart systems
- Wide sphere range — −19.00 D to +16.75 D covers virtually all refractive errors encountered in clinical practice
- Smooth lens transitions — precision-built dial mechanisms allow fast, backlash-free sphere and cylinder changes
- Maddox rod & red/green filters — integrated auxiliary lenses for binocular balance testing without separate trial frame accessories
- Rotary prism 0–20Δ — handles prismatic corrections directly in the phoropter head
- Wide PD range (48–80 mm) — accommodates diverse patient populations including pediatric and high-PD patients
Clinical Applications
- Routine subjective refraction for spectacle or contact lens prescriptions
- Binocular balance testing using Maddox rod and red/green filters
- Prism assessment and prismatic correction fitting
- Pre-surgical refraction workup (cataract, refractive surgery)
- Low vision assessment requiring extended sphere range
Who This Is For
- Optometry practices — primary refraction workhorse for general and specialty lanes
- Ophthalmology clinics — reliable backup or primary instrument in examination suites
- Teaching institutions — durable, easy-to-teach minus-cylinder platform for student training
- Mobile / satellite clinics — cost-effective illuminated phoropter for secondary locations
Condition & Warranty
Used. All lenses have been cleaned and dial mechanisms lubricated before shipment. Note: the illumination function has not been tested — the functionality of the built-in lights is unknown and not guaranteed; buyer is responsible for obtaining the correct power cable for testing. All refractive functions are fully operational. Covered by a 90-day warranty on refractive parts and workmanship (illumination excluded).
