title: The SRK regression formula in calculating the dioptric power of intraocular lenses.
abstract: One hundred and seventy one eyes with intraocular lenses were studied to compare the predictive accuracy of the Fyodorov and Van der Heijde theoretical formulae of the Sanders-Retzlaff-Kraff (SRK) regression formula. The SRK regression formula was the most accurate. Our personal calculations of the A constants of this formula are given for several types of implants and manufacturers.
