Haag-Streit Eyestar 900

Description

With the Eyestar 900, Haag-Streit is opening a new chapter in measuring, imaging, and diagnosing the human eye with the introduction of a complete swept-source OCT-based eye analyser. This optical biometer features swept-source technology enabling precise measurement and topographic assessment of the front and back corneal surface and the anterior chamber, including the lens, as well as imaging of all these structures. It also includes cornea-to-retina biometry of the entire eye.

The swept-source OCT-based technology provides topography of the front and back corneal surface, pachymetry maps, biometry, and A- as well as B-scan imaging in a single measuring procedure on a single device, enabling precise measurements and excellent cataract penetration in a fully automated, fast data acquisition process. The device also features well established dual-zone reflective keratometry, specifically for cataract applications, providing IOL constant compatible keratometry and astigmatism measurements.

The fully automated measurement process enables the user to reliably acquire measurement and swept-source OCT imaging data for both eyes in less than 40 seconds. EyeSuite IOL software offers latest generation IOL calculation methods including Hill-RBF, Barrett, and Olsen, simplifying IOL selection without the need to transfer data and risk transcription errors.

FEATURES

• Swept-Source OCT for Greater Safety: Imaging of the entire anterior chamber, including the crystalline lens, allows the user to easily verify any measurement and identify anatomical anomalies that may interfere with planned surgical procedures.
• Tear Film Independent Topography: Eyestar 900 provides corneal topography in compliance with Class A topographer standards. The maps of the cataract suite cover 7.5 mm in diameter and provide comprehensive information about the front and back of the cornea and pachymetry.
• Fully Automated Measurement: The fully automated measurement process enables the user to reliably acquire precise measurement and swept-source OCT imaging data of both eyes in less than 40 seconds.
• Easy to Delegate: In busy practices, it is important to allocate resources efficiently and purposefully. The Eyestar 900 workflow uses optimised automation to free up eye care specialists' time for diagnosis and planning.
• Patient Compliance and Efficacy: Patients, especially elder patients, tend to tire quickly during an eye exam, impairing optimal data collection. The fully automated data acquisition process, and its fast measurement with simultaneous data recording, lead to excellent patient comfort and cooperation, which has a positive effect on the measurement quality.
• Dual-Zone Reflective Keratometry: The Eyestar 900 features well-established, dual-zone reflective keratometry specifically for cataract applications, providing precise, IOL-compatible keratometry and astigmatism measurement.
• Anterior and Posterior Corneal Topography: Topographic maps of the anterior and posterior cornea and pachymetry maps from the Eyestar 900 enable users to improve their surgical plan and review patients' suitability for specific interventions.
• Integrated IOL Calculation: EyeSuite IOL offers the latest generation IOL calculation methods, including Hill-RBF, Barrett, and Olsen. This simplifies IOL selection without transferring data between systems.

Frequently Asked Questions

What is swept-source OCT technology?

Swept-source optical coherence tomography uses light to produce detailed cross-sectional images of ocular structures. In the Eyestar 900, this technology allows clinicians to review the anterior chamber and crystalline lens while verifying measurements and identifying anatomical characteristics that may affect surgical planning.

How can the Eyestar 900 support cataract surgery planning?

The system provides biometry, corneal topography, pachymetry, and anterior-segment imaging that clinicians can use when evaluating patients and planning procedures. Its imaging may also help users review anatomical anomalies and assess suitability for options such as toric or multifocal intraocular lenses.

How long does an Eyestar 900 measurement take?

The Eyestar 900 can automatically acquire precise measurement and swept-source OCT imaging data for both eyes in less than 40 seconds.

Can Eyestar 900 measurements be delegated to staff?

Its workflow-optimized automation is designed to make routine data acquisition easier to delegate. This can allow eye care specialists to spend more time reviewing results, making diagnoses, and planning patient care. Staff should receive all required training before operating the system.
