Marco G2 Ultra — Used 3-Step Slit Lamp with Haag Streit 870 Tonometer
The Marco G2 Ultra is the entry-tier of Marco’s Ultra Series — a 3-step Galilean slit lamp paired here with the Haag Streit 870 (Goldmann-type) applanation tonometer. This used marco g2 ultra ships ready as a complete slit-lamp + tonometer station at a sub-$4K price point — significantly less than the 5-step G5 Ultra while retaining the same Marco optical platform.
The G2 Ultra delivers 10× / 16× / 25× magnification through a Galilean parallel magnification changer with 6° converging binocular tubes. Slit width and slit height are both continuously variable from 0 to 14 mm — the widest slit range in Marco’s product family — making this slit lamp particularly versatile for sclerotic-scatter and conic-section illumination techniques. High-eyepoint wide-field eyepieces accommodate operators with eyeglasses.
According to a National Library of Medicine-indexed study (Can J Ophthalmol, 2015), yellow- and blue-filtered fluorescein imaging produces clinically superior conjunctival and corneal staining contrast — the standard slit-lamp biomicroscopy workflow the G2 Ultra was designed for.
Why Practices Choose the G2 Ultra
3-step magnification (10× / 16× / 25×) — covers the routine biomicroscopy range; cleanly stepped without the cost of the G5’s 5-step turret.- Wide 0–14 mm slit width and height — widest slit range in Marco’s Ultra Series; supports conic, optic-section, and sclerotic-scatter illumination techniques.
- Galilean parallel magnification changer — single-knob magnification switching with sharp depth perception across the full magnification range.
- 6° converging binocular tubes — comfortable observer position; high-eyepoint wide-field eyepieces accommodate operators with eyeglasses.
- Marco Ultra Series optical platform — shares the same optics quality as the G5 Ultra; the difference is the magnification range, not the optical engine.
- Integrated Haag Streit 870 tonometer — Goldmann-type applanation tonometry on the same instrument; eliminates separate tonometer purchase.
- Made in USA assembly — Marco assembles slit lamps in Florida; widely supported for parts and service.
- Sub-$4K used price — one of the most cost-effective full-featured slit-lamp + tonometer combos at this tier.
Clinical Applications
- Routine slit-lamp biomicroscopy — anterior-segment evaluation including cornea, iris, lens, and anterior vitreous.
- Goldmann applanation tonometry — gold-standard IOP measurement for glaucoma evaluation and follow-up.
- Contact-lens fitting — fluorescein staining and fit assessment with cobalt-blue + neutral-density filters.
- Corneal disease grading — staining patterns, abrasions, ulcers, and post-surgical wound evaluation.
- Cataract grading — direct illumination and retroillumination across 10× / 16× / 25× range.
- Glaucoma anterior-chamber assessment — slit-beam evaluation of AC depth, pigment dispersion, pseudoexfoliation.
Who This Is For
- Optometry and general ophthalmology practices wanting a Marco-branded slit-lamp + tonometer combo at the entry-tier price point.
- Multi-doctor groups standardizing on Marco’s Ultra Series across their lanes — G2 for general use, G5 for retina specialty.
- Practices that mostly perform routine biomicroscopy at 10× / 16× / 25× and don’t need the 6.3× wide-field or 40× high-mag of the G5.
- Buyers seeking a wide slit-width range (0–14 mm) for advanced illumination techniques.
