Keeler Ophthalmic Ultrasound

Keeler’s ophthalmic ultrasound family gives practices two flexible paths. The 4Sight platform is a modular all-in-one touchscreen console that combines A-Scan biometry, B-Scan imaging, UBM (ultrasound biomicroscopy), and pachymetry with interchangeable probes. For practices that already have a Windows PC in the lane or prefer a lighter footprint, the Plus probe line — A-Scan Plus Connect, B-Scan Plus, and UBM Plus — plugs directly into any Windows laptop or desktop via USB, turning it into a portable ophthalmic ultrasound station with no dedicated console required.

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.

Keeler A-Scan biometry measurement for IOL calculation

A-Scan Biometry — Axial length measurement with IOL formula calculation

Keeler B-Scan posterior segment imaging

B-Scan Imaging — Posterior segment visualization through media opacities

Keeler UBM high-resolution anterior segment imaging

UBM Imaging — High-resolution anterior segment and angle visualization

Portable Probe Line

Keeler Plus Probes — Windows PC Plug-and-Play

Keeler’s Plus probe family gives practices a lightweight alternative to a dedicated console. Each probe plugs into any Windows laptop or desktop via USB and ships with Connect software — turning a computer you already own into a portable ophthalmic ultrasound station. Popular with multi-location groups, satellite clinics, and practices that want modality flexibility without another piece of lane furniture.

A-Scan Plus Connect

Biometry on any Windows PC. Contact and immersion modes with 6 IOL formulas and 4 post-refractive formulas for cataract planning. Ships with footswitch, power adapter, test block, immersion shell, and Keeler Connect software. Ideal for satellite surgical centers and mobile biometry.

B-Scan Plus

12/15 MHz dual-frequency posterior-segment imaging with 0.015 mm axial resolution, 60° scan angle, 2× smooth zoom, and adjustable film loops from 2–17 seconds. Twelve measuring calipers, adjustable gain (0–112 dB), PDF reporting. Plugs into any Windows laptop or desktop via USB.

UBM Plus

48 MHz ultrasound biomicroscopy of the anterior segment — cornea, iris, ciliary body, zonules, crystalline lens, and IOL position. 60° sweep, guarded safety tip, DICOM-ready. Portable USB probe with Accutome Connect software. Reverse compatible with the 4Sight console.
