TRS-3100 Automated Refraction System
A feature-streamlined instrument that offers completely wireless interface with the autorefractor and autolensmeter. The built-in IC card reader allows for seamless integration and connection without any cable logistics. Used in a traditional lane, reduces refraction time and can be networked into a paperless EMR system. Positioned aggressively, this system features a dedicated real time processor that delivers outstanding operational speed, responsive specificity of function, tremendous simplicity of use, and the security of sustained performance integrity, and 40 years of Marco Customer Care Support in the refraction equipment industry.

TRS-3100

Compact Design
The TRS-3100 is compact and the ergonomic design covers less of the patient’s face, offering a more comfortable examination.
Convergence And PD
During near point tests, power convergence and power PD are adjusted automatically. PD can be adjusted independently for more accurate and reliable measurements.
Advanced Dial
The S/C/A Mode keys in the center of the dial allow the operator to quickly refine sphere, cylinder, and axis using only one hand.
Enhanced Connectivity
Total Refraction System offers a wireless interface with Marco autorefractors and autolensmeters. The built-in Intelligent Card (IC) Reader allows seamless integration without cable constraints and costs.
The TRS-3100 features Rapid-Reflex℠ keypad technology speeds up refining of sphere, cylinder, and prism lenses, with instantaneous comparisons to current Rx or unaided to corrected vision
Digital Benefits
The TRS-3100 total refraction system offers a wireless interface with Marco autorefractors and autolensmeters. The built-in intelligent card (IC) reader allows seamless integration without cable constraints. And combined with Marco Connect it is easier than ever to transfer data from pre-test equipment to the TRS-3100 and download all this information to an EMR system.


Ergonomic Design
The TRS-3100 is compact and the ergonomic design covers less of the patient’s face, offering a more comfortable examination. A wide visual field (40°) provides a natural view of the environment enabling more realistic and accurate refractions.
Convergence & PD
During near point tests, power convergence and power PD are adjusted automatically. PD can be adjusted independently for more accurate and reliable measurements.


Keypad With Touch Monitor
The 5.7 inch LCD color monitor gives enhanced, illuminated detail with touch screen function. The compact design of the keypad maximizes work-space and user comfort, avoiding the risk of shoulder and neck injury. An advanced dial with S/C/A mode keys in the center of the dial allow the operator to quickly refine sphere, cylinder, and axis using only one hand.
Enhanced Refinement
Extremely small increments of measurement may be used with the TRS-3100. Axis refinements are 1-5° and prism adjustments are 0.1-1.00. Immediate justification is accomplished by comparing the old Rx to the subjective with a single push of a button.
