Keeler Ophthalmic Ultrasound

Keeler’s ophthalmic ultrasound family is built around the 4Sight platform — a modular all-in-one system that combines A-Scan biometry, B-Scan imaging, UBM (ultrasound biomicroscopy), and pachymetry in a single touchscreen console with interchangeable probes. For practices and surgical centers that need diagnostic ultrasound capabilities tailored specifically to ophthalmic applications — from pre-cataract axial length measurement to posterior segment imaging when media opacities prevent direct visualization, to high-resolution anterior segment and angle analysis.

Practice Fit

Where Keeler Ultrasound Wins

If your practice needs modular ophthalmic ultrasound capabilities — biometry, posterior segment imaging, anterior segment analysis — from a single expandable platform, the 4Sight system delivers.

Best Fit

Cataract surgeons needing reliable biometry, retina specialists requiring posterior segment imaging through opaque media, and anterior segment specialists performing angle and ciliary body analysis — particularly practices that want modular ultrasound capabilities from a single platform.

Why This

Rather than purchasing separate A-Scan, B-Scan, and UBM systems, the 4Sight platform lets practices start with one modality and add probes as clinical needs grow. Shared console, shared software, one DICOM workflow.

Practice Impact

Modular investment path means practices pay for the ultrasound capabilities they need now and expand later. Portable USB probes also work with the standalone Connect software on any Windows PC, adding flexibility for multi-location practices.

Platform Strengths

Why Practices Choose Keeler Ultrasound

Modular All-in-One Platform

Start with A-Scan biometry for cataract planning, add B-Scan for posterior segment imaging, add UBM for anterior segment analysis. One console, one workflow, one investment path.

Ophthalmic-Specific Design

Every probe and algorithm is built for eye care applications. A-Scan includes 6 IOL formulas and 4 post-refractive formulas. B-Scan delivers 0.015 mm resolution. UBM provides 48 MHz high-resolution anterior segment imaging.

Flexible Deployment

Probes work with both the 4Sight touchscreen console and the standalone Connect software on any Windows laptop. No software licensing fees. DICOM ready with automatic EMR exports.

Modality Diversity

Keeler Ultrasound Imaging Modes

The 4Sight platform supports multiple ophthalmic ultrasound modalities — A-Scan biometry, B-Scan posterior segment imaging, and UBM anterior segment analysis from a single console.
