Description
Zeiss Cirrus Anterior Segment Premier Lenses — Refurbished Add-On Module
The Zeiss Cirrus anterior segment Premier Lenses are the official optical attachment that extends any Cirrus OCT platform — the 400, 4000, 500, 5000, and 6000 — into a full anterior segment imaging system. Without this add-on, the Cirrus captures only posterior segment data. With it attached, the same instrument delivers high-resolution HD OCT scans of the cornea, anterior chamber, chamber angle, and full wide angle-to-angle views in a single seamless workflow. Buying a refurbished Zeiss Cirrus anterior segment module is the most cost-effective way to unlock these capabilities on an existing Cirrus system — no new instrument purchase, no new installation footprint, and no retraining for staff already familiar with the Cirrus interface. This set is refurbished, inspected for optics and mechanical integrity, and covered by Digital Eye Center’s 6-month warranty.
Research published by the National Library of Medicine confirms that anterior segment OCT provides clinically superior visualization of corneal microstructure, angle anatomy, and anterior chamber dimensions compared to slit lamp biomicroscopy alone — establishing it as an essential tool in modern anterior segment disease management.
What's Included
- Zeiss Cirrus Anterior Segment Premier Lens set
- 6-month Digital Eye Center warranty
Why Practices Choose the Zeiss Cirrus Anterior Segment Module
- Unlocks anterior segment scanning on existing Cirrus hardware — eliminates the need to purchase a separate anterior segment OCT instrument, maximizing return on the Cirrus investment already in the practice.
- Broad model compatibility — a single module set covers Cirrus 400, 4000, 500, 5000, and 6000 platforms, making it a future-proof accessory when upgrading from one Cirrus generation to the next.
- HD Cornea scanning — delivers high-density cross-sectional scans of the cornea with the same Cirrus optical coherence technology used for retinal imaging, providing detailed visualization of corneal layers and epithelial maps.
- Wide Angle-to-Angle imaging — captures the entire anterior chamber in one scan, including both angles, for glaucoma angle assessment without requiring a separate gonioscope or dedicated anterior OCT system.
- Pachymetry mapping — produces corneal thickness maps directly from OCT data for refractive surgery screening, keratoconus monitoring, and post-procedure follow-up.
- Familiar Cirrus workflow — anterior segment scanning follows the same acquisition steps as posterior scans, so no additional training is required for staff already operating the Cirrus daily.
- Quick attach/detach design — the lens mounts to the instrument lens mount without tools, allowing the same Cirrus to switch between posterior and anterior workflows within seconds.
- Refurbished value — professionally refurbished optics at a fraction of the cost of a new module or a separate dedicated anterior segment OCT system.
Scan Types Enabled
- HD Cornea — high-density cross-sectional corneal scan with layer visualization for pathology assessment and surgical planning.
- Anterior Chamber scan — cross-sectional view of the full anterior chamber depth and geometry.
- Wide Angle-to-Angle — panoramic anterior segment scan capturing both iridocorneal angles in one acquisition for glaucoma evaluation.
- HD Angle — focused high-resolution scan of the iridocorneal angle for narrow-angle assessment and angle closure screening.
- Pachymetry — corneal thickness mapping for refractive surgery candidates, keratoconus suspects, and post-LASIK/PRK monitoring.
Scanning Workflow
Attaching the anterior segment lens is the only setup step required — for Cirrus 500 and 5000 models, the anterior segment scan types automatically appear in the scan list once the lens is mounted. For Cirrus 400 and 4000 models, the lens is selected from the Lens menu in software to activate the scan types. The anterior segment scan workflow mirrors the familiar posterior segment acquisition process: select scan type, align using on-screen X-Y and Z controls, instruct the patient to fixate on the target and open their eyes wide before capture, then review and save.
Key differences from posterior scanning include the absence of a fundus image reference, no FastTrac eye tracking, and a blurry fixation target appearance during lens-required anterior scans — all expected behaviors documented in the Cirrus Instructions for Use. Alignment is confirmed by a strong vertical reflex in both viewports indicating correct centering on the corneal vertex.
The on-screen workflow guides the technician through each acquisition step with the same interface used for retinal scans, meaning practices can integrate anterior segment imaging into their existing pre-exam routine without disrupting the established patient flow. Image quality and scan reliability are consistent with the Cirrus platform’s clinical reputation, giving physicians confidence in the anterior segment data delivered pre-exam.
Corneal vertex centering is visually confirmed on screen: when a strong vertical reflex appears in both viewports simultaneously, the scan is properly centered and ready to capture. This objective alignment indicator removes guesswork and ensures repeatable scan positioning across different operators and patient visits, which is critical for longitudinal corneal monitoring in keratoconus and post-surgical cases.
Who This Is For
- Cirrus OCT owners (400, 4000, 500, 5000, or 6000) who want to add anterior segment imaging capability without purchasing a separate dedicated instrument.
- Cornea and refractive practices needing pachymetry, HD Cornea OCT, and angle imaging for surgical screening and post-operative monitoring within the same workflow as retinal imaging.
- Glaucoma practices using Cirrus for RNFL and ONH monitoring who want angle imaging capability added to the same platform.
- Multi-physician groups looking to maximize utilization of existing Cirrus hardware with expanded diagnostic scope at low incremental cost.
