MediWorks AL550 Optical Biometer for Cataract Surgery

Description

The MediWorks AL550 is an automatic optical biometer developed for cataract surgery planning, intraocular lens power calculation and comprehensive anterior corneal analysis.

Its Optical Low-Coherence Reflectometry system uses a 1,060 nm wavelength to obtain axial biometric measurements. The longer wavelength provides strong penetration and supports a high measurement-success rate in cataract patients.

The AL550 combines axial biometry with 50-ring Placido topography. It analyzes up to 125,600 data points across the anterior corneal surface and can obtain up to 22 clinical parameters during a single measurement.

Key measurements include axial length, anterior chamber depth, central corneal thickness, crystalline-lens thickness, corneal curvature, white-to-white distance and pupil diameter. These parameters support IOL power prediction and refractive cataract surgery planning.

The integrated calculation software includes multiple IOL formulas, including Pearl-DGS, Jin, SRK/T, Holladay 1, Hoffer Q and Haigis. Availability of formulas should be confirmed for the selected software configuration.

In addition to cataract applications, the system provides keratoconus screening, anterior corneal wavefront analysis, visual-quality simulations, myopia progression monitoring and orthokeratology fitting functions.

Automatic XYZ tracking, autofocus, rapid capture, automatic eye recognition and voice prompts help standardize measurements and simplify the clinical workflow.
