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.
Despite advanced technology, certain "difficult" eyes remain a challenge for biometry:
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.
The curvature of the cornea, which provides its refractive power.
Used both AL and K to predict ELP. These remain widely used today.
