A-Scan ultrasound probe – 4Sight platform compatible
High quality visuals and accurate biometric measurements, on demand
This unit contains everything you need to get you up and running on Keeler 4Sight™ – our all-in-one ultrasound solution.
The most demanding cataract surgery requires powerful equipment and the A-Scan is the single most effective solution for measuring, calculating and refining your refractive cataract surgical outcomes. Designed to take accurate biometric measurements, the A-Scan probe can be used to measure ocular axial length in contact or immersion modes and it is particularly useful for patients or animals with fixation difficulties or dense cataracts.
Compatible with both Keeler Connect software (which can be used on any laptop or desktop computer) and Keeler 4Sight™ ultrasound system, the A-Scan probe is intuitively designed and fully portable, making it the perfect companion for busy eye imaging professionals, either in clinic or on-the-go.
Benefits:
- Improved visuals
- Easy to use interface with time-saving functionality
- Wavelength spike patterns for accurate and precise measurements
- Includes six IOL formulas
- Includes four post-refractive formulas
- Competitive warranty and great customer support
- Fully compatible with Keeler 4Sight™ – giving you unmatched storage space
Description
High quality visuals
Record and save unlimited images and videos with the B-scan probe and the Keeler 4Sight™ software, to assist with diagnosing, record keeping and even teaching future generations of eye care professionals.
Featuring optimised lens constants for improved visuals, the A-scan probe allows you to see visuals that would otherwise be obscured by cataracts or vitreous haemorrhages, providing superior surgical outcomes for your patients.
Easy to use interface
The smooth interface makes the A-scan probe easy to use, and allows you to create default settings that you can go back to again and again without interruptions. The system also automatically creates electronic medical records for your patients, giving you peace of mind for future examinations.
Wavelength spike patterns
Working on 10 MHz broadband, the A-Scan probe can be used to measure ocular axial length in both contact or immersion modes. Each measurement with the A-scan captures up to 5 wavelength spike patterns, using independent velocities for each portion of the eye, as well as the average and standard deviation of each anatomical measurement to give you the most accurate results.
IOL formulas
Includes 6 IOL formulas: Hoffer Q, SRK/T, Holladay I, Haigis, SRK II, Binkhorst II.
Post refractive formulas
The A-scan also has post refractive measurement capabilities, using 4 formulae: Contact Lens, Entered, Clinical History and Shammas Clinical.
Great value
At Keeler, we believe that value is more than the price alone. We look at every detail and quality components, results and high build quality shouldn’t cost the earth.
