The handheld, portable ophthalmic ultrasound needed to take precise axial length measurements and access the densest of cataracts.


Why Do You Need an A Scan?
With the A Scan attachment from Micro Medical Devices, axial length can now be measured from a device that sits in the palm of your hand! An A scan makes preparation for cataract surgery much easier than ever before by enabling precise measurement of the eye’s length for calculating refractive power and choosing the perfect IOL to implant during cataract surgery. Our A Scan probe can also be used to measure the Axial Length of the eye for Myopia control.
Why Our A Scan?
As a portable, multimodal tool, the MMD A Scan probe is flexible and easy to transport, making it ideal for doctors traveling between offices, on mission trips, or in nursing facilities and hospitals. Our device has been proven as clinically accurate as a laser interferometer and can penetrate a dense or opaque cataract. It works in both applanation and immersion modes, integrates into a range of different systems, and is compatible with our convenient, disposable EZ Tips!
For Cataract Surgery
The ability to accurate measure axial length is critical to the calculations needed to select an IOL that maximizes visual outcomes after cataract surgery. It helps assess refractive power in pre-surgical workups and helps you reduce unhappy post-operate patients.
For Myopia Management
Proper assessment of childhood myopia depends on the ability to produce reliable, repeatable axial length measurements. Because refractive error caused by myopia doesn’t always correlate directly with the rate of axial elongation, the A Scan can help guide treatment decisions for myopia.
