Calculations - Pdf | Biometry & Iol Power

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

Used both AL and K to predict ELP. These remain widely used today. 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. Biometry is the measurement of the eye's physical dimensions
