Abstract

AbstractThe PEARL-DGS formula is a thick lens formula that uses AI techniques to predict the distance between the posterior corneal surface and the anterior IOL surface (“theoretical internal lens position,” TILP). The TILP value was back-calculated from refractive outcome in a large dataset. The refractive index values used in the formula are those of the Atchison eye model, except for the corneal index, which was determined empirically during the formula development process. In our case, this value was 1.363. The performance of the formula was evaluated in different studies with a high level of precision and accuracy, comparable to the latest formulas in the field.
