Marco G5 Ultra — Used 5-Step Slit Lamp with Integrated Goldmann Tonometer
The Marco G5 Ultra is the fixed-turret flagship of Marco’s Ultra Series — pairing high-contrast Galilean optics with a single-knob 5-step magnification turret (6.3× / 10× / 16× / 25× / 40×) and an integrated Haag Streit 900 (Goldmann-type) applanation tonometer. This used marco g5 ultra ships ready for clinical deployment as a complete slit-lamp + tonometer station.
Compared to its predecessors, the Ultra Series platform delivers a 20% increase in light transmission, a 15% wider field of view, and a 14% increase in depth of field — improvements that make corneal endothelium and anterior-chamber detail noticeably sharper at high magnification. Galilean optics and 6° converging binocular tubes provide a comfortable observer position; 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 G5 Ultra was designed for.
Why Practices Choose the G5 Ultra
5-step single-knob turret (6.3× / 10× / 16× / 25× / 40×) — wide magnification range without changing eyepieces; one knob switches all five steps cleanly.- 20% more light transmission — Ultra Series optics versus prior Marco platform; sharper detail at the high-mag end.
- 15% wider field of view — covers more anterior-segment area per glance, reducing tilt/translate motions during exam.
- 14% greater depth of field — keeps more of the cornea, AC, and lens in focus simultaneously.
- Galilean optics, 6° converging tubes — comfortable observer position with high-eyepoint wide-field eyepieces.
- Cobalt blue + neutral-density filters — built-in filter set for fluorescein and bright-anterior-segment exam without filter swapping.
- Continuously variable slit width — fine slit control from pinpoint to full beam.
- Integrated Haag Streit 900 tonometer — Goldmann-type applanation tonometry on the same instrument; eliminates the need for a separate tonometer purchase.
Clinical Applications
- Routine slit-lamp biomicroscopy — full anterior-segment evaluation (cornea, iris, lens, anterior vitreous).
- Goldmann applanation tonometry — gold-standard IOP measurement for glaucoma evaluation and follow-up.
- Corneal disease grading — staining patterns (fluorescein with cobalt), abrasions, ulcers, post-surgical wounds.
- Contact-lens fitting and follow-up — cobalt-blue fluorescein evaluation for fit and corneal staining.
- Cataract grading — direct illumination, retroillumination, sclerotic scatter.
- Vitreoretinal contact-lens biomicroscopy — Goldmann or Volk indirect lenses for posterior-segment review.
Who This Is For
- Optometry and general ophthalmology practices that want a full-featured 5-step slit lamp + Goldmann tonometer at a sub-$6K used price point.
- Multi-doctor groups standardizing on Marco’s Ultra Series platform across all lanes.
- Practices replacing a 2- or 3-step slit lamp with a 5-step unit for finer magnification control across the full clinical range.
- Buyers who want a single-vendor slit-lamp + tonometer combo on one PO rather than mixed components.
