What is an Axial Length scan?
An axial length scan (sometimes called an “A-Scan”) takes a measurement of the eye’s length from the front surface to the very back of the eye.
How are Axial Length measurements used?
This measurement is primarily used to monitor myopia progression in children. Routine axial length scans paired with glasses prescription checks can indicate if myopia is worsening or if myopia treatment is remaining effective.
