The total length of the eye from the cornea to the retina.

Biometry is the measurement of the eye's physical dimensions. To calculate the correct IOL power, surgeons need two primary measurements: Biometry & IOL Power Calculations - PDF

Once measurements are taken, they are plugged into mathematical formulas to predict the necessary lens power. These formulas have evolved through "generations" based on how they estimate the —the final resting place of the IOL in the eye. The total length of the eye from the cornea to the retina

The curvature of the cornea, which provides its refractive power. which provides its refractive power.
