Additionally, refractive prediction error was observed and defined as the difference between predicted and postoperative spherical equivalents. Formula performance was assessed using mean absolute error (MAE), mean numerical error, median absolute error, and proportion of eyes achieving predefined refractive accuracy (\u00b10.25 D, \u00b10.50 D, \u00b11.00 D, and \u00b1 2.00 D).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>\n                      Barrett Universal II showed the lowest calculation of MAE (0.54 \u00b1 0.71 D), followed by SRK\/T (0.57 \u00b1 0.75 D) and Haigis (0.61 \u00b1 0.69 D).
