Marco G5 Ultra Slit Lamp — Used Complete Biomicroscope with Integrated Applanation Tonometer

Research published in Clinical Ophthalmology (National Library of Medicine) confirms that Goldmann applanation tonometry remains the reference standard for intraocular pressure accuracy in clinical practice — underscoring the importance of an integrated tonometer in any complete anterior segment exam station.
Why Practices Choose the Marco G5 Ultra Slit Lamp
5-step magnification drum (6.3×–40×) — Galilean optics with high-eyepoint, wide-field eyepieces provide clear, high-contrast imaging across all five steps without changing eyepieces; single-knob rotation switches magnification steps cleanly.
- Integrated applanation tonometer included — IOP measurement capability built into the slit lamp eliminates a separate tonometer purchase; keeps the exam lane complete with one instrument.
- Cobalt blue filter for fluorescein evaluation — enables fluorescein staining assessment for corneal abrasions, contact lens fitting, dry eye evaluation, and surface pathology without an add-on filter accessory.
- Neutral density filter — reduces illumination intensity for photosensitive patients without altering slit geometry, improving comfort and compliance during prolonged anterior segment examination.
- Continuously variable slit control — variable width, height, and rotation support diffuse, direct focal, retroillumination, and specular reflection examination techniques across all anterior segment structures.
- Enhanced halogen illumination — Marco Ultra Series halogen delivers up to 20% greater light transmission versus previous models; warm-spectrum output renders anterior segment tissue clearly in routine clinical use.
- 6° converging binocular tubes — ergonomic angle reduces operator head and neck strain during extended examination sessions; high-eyepoint eyepieces accommodate spectacle wearers without field-of-view compromise.
- Single-handed elevation system — streamlines patient positioning, enabling faster lane throughput and consistent instrument alignment during biomicroscopy and tonometry.
Clinical Applications
- Anterior segment biomicroscopy — cornea, conjunctiva, iris, lens, and anterior vitreous examination with five-step Galilean optics and full slit illumination control.
- Applanation tonometry — intraocular pressure measurement for glaucoma screening, monitoring, and routine comprehensive eye exam documentation.
- Fluorescein staining evaluation — cobalt blue filter supports corneal abrasion mapping, dry eye fluorescein TBUT assessment, and contact lens fitting evaluation.
- Foreign body and trauma assessment — variable magnification and illumination modes for anterior segment emergency examination in urgent care settings.
- Pre- and post-operative evaluation — anterior segment assessment before and after cataract, refractive, and corneal procedures with documented biomicroscopy findings.
Who This Is For
- New ophthalmology and optometry practices equipping a first exam lane on a budget without sacrificing IOP measurement capability or optical quality.
- Multi-location clinics adding slit lamps to satellite offices or secondary lanes where a complete, reliable instrument is needed at a cost-effective price.
- Urgent care eye clinics and mobile screening operations that need a full-featured, functional instrument without a premium brand price tag.
- Teaching programs and residency clinics seeking affordable student-use slit lamps with full clinical capability including integrated tonometry.
