axial length
Cornea-to-retina distance
Axial length is the distance from the front to the back of the eye, measured from the cornea to the retina.
Ophthalmologists measure axial length to calculate the power of intraocular lens implants before cataract surgery and to monitor conditions like myopia, where elongation of the eye causes nearsightedness.
