Working Principle:
The ultrasound A-scan works by projecting a sound wave through the eye and then measuring reflections. A reflection happens at the junction of two different densities, such as the interface between the posterior lens capsule and the vitreous. These echoes are shown as tall spikes of a high amplitude on the display, hence the name amplitude-scan, which is often abbreviated as A-scan.
A-scan ultrasound is used to take measurements for artificial lenses for cataract surgery. This quick and painless procedure can be performed in your doctor’s office.
