Formula to calculate power


The SRK regression formula in calculating the dioptric power of intraocular lenses.

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 regressio...
