Topcon DRI OCT Triton
Modality: Ophthalmic OCT
Topcon's premium swept-source OCT / OCT-A platform — 1050 nm wavelength enables deeper choroidal penetration than conventional spectral-domain (840 nm) systems. Direct competitor to premium tier of Zeiss Cirrus 6000 and Heidelberg Spectralis. Strong adoption in retinal practices that prioritize choroidal disease assessment, diabetic-retinopathy screening, and high-volume OCT-A workflow.
Distinctive technology
- Swept-source OCT at 1050 nm — deeper choroidal penetration; reduced sensitivity roll-off with depth vs spectral-domain.
- 100,000 A-scans / sec acquisition rate.
- OCT-Angiography (OCT-A) standard — dye-free retinal vascular imaging.
- Wide-field 12×12 mm scan — extended retinal coverage in a single acquisition.
- Integrated color fundus camera for paired fundus + OCT in a single workflow step.
- Enhanced choroidal imaging for choroidal-thickness analysis, polypoidal choroidal vasculopathy, central serous chorioretinopathy.
Clinical use
- Retinal disease — AMD, diabetic retinopathy, vein occlusions, choroidal disease, polypoidal choroidal vasculopathy.
- OCT angiography — dye-free vascular assessment, fluorescein-angiography substitute or adjunct.
- Glaucoma — RNFL + GCL analysis on configured units.
- Anterior-segment OCT with appropriate module.
Refurb posture
- Established refurb supply in regions with large Topcon installed base (Asia-Pacific, Europe).
- Software-version + OCT-A licensing is the price-determining variable.
- Vendor lock-in on patient longitudinal records — Topcon-to-Topcon refurbs preserve serial-comparison data continuity.
