A-scan and B-scan are both eye ultrasonography scans. Although both the scans are based on the principle of ultrasonography, they differ in certain aspects. A-scan. A-scan is the short form for amplitude scan. This eye ultrasound gives details about the length of the eye. It is a one-dimensional scan of the eye.

Nov 1, 2024 · In cataract surgery, an A-Scan is used to determine the power of the intraocular lens (IOL) that will be implanted to replace the natural lens. A-Scan measurements and calculations include axial length, anterior chamber depth, and lens thickness, which are crucial for IOL power calculation.

An “A” Scan is a highly precise measurement of the eye used to help us choose the correct lens implant power before cataract surgery. Our office uses state of the art technology with the Zeiss IOL Master, a totally noncontact instrument.

Compare or Get quote for selected. Portable, affordable full function multi probe unit, with A-Scan, B-Scan and UBM capabilities. High resolution images with 256 lines per scan. Zoom control enhances diagnostic capability. Images can be enlarged while …

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.

Working in harmony with Keeler Connect software (which can be plugged into any Windows™ laptop or desktop computer), A-Scan Plus Connect is intuitively designed and fully portable, making it the perfect companion for busy eye imaging professionals, either in clinic or on-the-go.

A-scan ultrasound biometry, commonly referred to as an A-scan (short for Amplitude scan), uses an ultrasound instrument for diagnostic testing. [1] A-scan biometry measures the axial length (AL) of the eye prior to cataract surgery in order to assess the refractive power of the intraocular lens that will be implanted.

Portable, digital, combination A-Scan and Pachymeter, with a large color touch screen, extreme accuracy, repeatable measurements and reliability. Immersion or direct contact A-scan. Manual or automatic capture (cataract, dense cataract, aphakic, silicone oil, and pseudophakic modes)

Oct 3, 2024 · How Does A-Scan Work in Cataract Surgery? A-Scan technology works by emitting high-frequency sound waves into the eye and measuring the time it takes for the waves to bounce back. These sound waves are harmless and painless, making A-Scan a safe and non-invasive procedure for patients.

Oct 5, 2024 · A-Scan, or Amplitude Scan, is a non-invasive diagnostic tool used in ophthalmology to measure the axial length of the eye and the dimensions of intraocular structures. This high-frequency ultrasound technique provides detailed information about the eye’s anatomy, including the lens, cornea, and vitreous.
