The total length of the eye from the cornea to the retina.
💡 Even a 1mm error in axial length measurement can result in a 2.5 to 3.0 diopter error in the final visual outcome. This highlights why high-precision biometry and modern formulas are non-negotiable for patient satisfaction. Biometry & IOL Power Calculations - PDF
The curvature of the cornea, which provides its refractive power. The total length of the eye from the cornea to the retina
