AL551 AUTOMATIC OPTICAL BIOMETER
Manufacturer: MEDIWORKS
Product code: BIOAL551
Precision biometry and corneal topography for modern myopia management
The Mediworks AL551 is an advanced automatic optical biometer combining OLCR axial biometry and Placido-disc corneal topography in a single streamlined platform.
Designed for everyday clinical workflow, the AL551 delivers fast, repeatable measurements to support myopia management, orthokeratology and anterior segment assessment.
With one automated capture, clinicians obtain comprehensive biometric and corneal data — helping improve clinical confidence while keeping patient chair time to a minimum.
Fast. Precise. Automatic.
Rapid measurement workflow
Binocular biometry can be captured in approximately 20 seconds, with guided voice prompts and simple two-click operation to support consistent results and minimal training time.
High-precision technology
Optical Low-Coherence Reflectometry (OLCR) at 1,060 nm provides strong signal penetration and high signal-to-noise ratio for accurate ocular measurements.
Fully automated alignment
Autofocus tracking and automatic OD/OS recognition simplify operation and help reduce operator dependency.
Combined biometry + topography in one capture
The AL551 integrates axial biometry and a 50-ring Placido disc topographer, capturing up to 125,600 analysis data points across the central cornea in a single session.
This allows clinicians to assess ocular structure and corneal shape without repeated measurements, improving workflow efficiency and patient comfort.
Comprehensive clinical parameters
The AL551 measures a wide range of ocular biometric and corneal metrics including:

Keratometry & cornea
-
Flat, Steep and Mean Keratometry (K1, K2, Km)
-
Kmax and Astigmatism
-
Corneal Radius & Axis
-
Eccentricity
-
Keratoconus indices
Advanced analysis
-
AL/CR ratio and trend analysis
-
Higher Order Aberration (RMS)
-

-
Corneal centre position (Alpha angle)
-
Pupil centre position (Kappa angle)
(22 parameters in total)
Designed for myopia management
The AL551 tracks axial length and AL/CR trends across age groups, supporting identification of myopia progression and development of targeted control strategies.
Clinicians can visualise progression curves and build customised management plans aimed at slowing axial elongation.
Orthokeratology & corneal screening
Ortho-K fitting support
Provides keratometry, eccentricity and corneal height data to assist trial lens selection and fitting.
Treatment evaluation
Tangential curvature difference maps allow before-and-after lens wear comparison.
Keratoconus screening
Sagittal curvature and elevation maps, together with keratoconus indices, support early detection of corneal abnormalities.
Clear reporting & easy workflow
A comprehensive digital report combines:
-
Biometric measurements
-
Corneal topography maps
-
Wavefront data
Helping clinicians evaluate ocular health and communicate findings clearly to patients.
The integrated touchscreen interface provides intuitive operation and a compact footprint suited to busy practices.
