Seven different formulae (Barrett Universal II, Castrop, Haigis, Hoffer Q, Holladay 1, Kane, and SRK\/T) were investigated to test the formula selection approach with regard to the calculated mean and median absolute prediction errors (MAE\/MedAE).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      The mean intraindividual difference in axial length was 0.2\u2009mm (\u00b10.3\u2009mm). BF1 coincided with the best\u2010fit formula for the second eye (BF2) in 56% of patients (\n                      <jats:italic>p<\/jats:italic>\n                      \u2009&lt;\u20090.05). Using BF1 for the second eye led to a lower MedAE (0.22\u2009dioptre, D) than using a formula at random (0.33\u2009D) and was less accurate than using the best\u2010fit formula for each eye separately (0.1\u2009D). The MedAEs of all formulae were generally low, ranging from 0.28 to 0.35\u2009D.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Using BF1 for the second eye led to a lower MedAE than the random selection of a formula.
