Axial length measurement

Axial length measurement refers to determining the distance from the front surface of the eye (cornea) to the back of the eye (retina). This measurement is essential for diagnosing and managing eye conditions like nearsightedness and for calculating the correct power of intraocular lenses for cataract surgery. Usually done with specialized electronic devices, it provides precise data that helps eye care professionals understand the eye’s size and shape. Accurate axial length measurement ensures better vision correction, whether through glasses, contact lenses, or surgery.
