A-Scan

The A-Scan provides two functions: one is to calculate the axial length (AL) of the eye and the other is to take that axial length along with a keratometer measurement and then calculate the best projected power of the proposed IOL.

The method by which the A-Scan calculates the AL is like radar. A sound impulse is echoed off the back of the eye and the time is takes for the echo to return to the probe is converted into the AL with an oscilloscope-type display.
