Product sheet · Heidelberg Engineering ANTERIONANTERION®
All-in-one swept-source OCT for the anterior segment: biometry and IOL calculation, corneal tomography, AC metrics and imaging.
ANTERION is an upgradeable all-in-one platform for the anterior segment, built on long-wavelength (1300 nm) swept-source OCT. One small-footprint device covers biometry and IOL power calculation, corneal topography and tomography, anterior chamber metrics and high-resolution imaging. Because the OCT images behind every measurement are shown, clinicians can see what they measure.
- 1300 nmswept-source OCT
- ~16,000corneal data points
- < 1 sfor 65 corneal B-scans
Key features
- 01
One device, whole anterior segment
Biometry including axial length, cornea exam, anterior segment imaging and patient consultation on one platform. It saves time and space and is easy to delegate.
- 02
Cataract planning with fewer surprises
True measurements of all refractive surfaces and the full corneal power (~16,000 data points). Spheric and toric IOL calculation with Barrett Suite, Haigis, Holladay 1, SRK/T, Hoffer® Q and OKULIX ray tracing.
- 03
Comprehensive cornea analysis
65 OCT B-scans in under one second. OU View differential maps show asymmetry, and Follow-Up View tracks surgical outcomes and disease.
- 04
Ectasia screening with SCORE
The SCORE Analyzer (by Dr. Gatinel and Dr. Saad) plus Ectasia View and the Epithelial Thickness Module support keratoconus screening and refractive surgery planning.
- 05
Angle assessment in 360°
Automatic scleral spur detection and 360° angle graphs complement gonioscopy for angle-closure assessment, along with AC volume, lens vault and ICL vault.
- 06
Expand as you grow
Start with the Imaging App and add the Cataract, Cornea and Metrics Apps when needed.
