Abstract
Purpose: To compare the accuracy of different power-calculation formulas in predicting the postoperative refraction of
three-piece and one-piece intraocular lenses (IOL).
Methods: We retrospectively reviewed the medical records of 74 eyes (62 patients) that had undergone cataract surgery involving
implantation of one of two IOLs―the SENSAR® AAB00 1-Piece Acrylic IOL (44 eyes), or the Hoya® VA60BB 3-Piece Acrylic
IOL (30 eyes)―between October 2014 and March 2015. Axial length was measured using an optical low-coherence refractometry
(Lenstar®), and biometry was then calculated by the pre-installed Lenstar program, which used the SRK/II,
Sanders-Retzlaff-Kraff/Theoretical (SRK/T), and Hoffer Q formulas. Mean absolute error (MAE) and mean numeric error (MNE)
were measured 1 day, 1 week, 1 month, and 2 months after surgery.
Results: Using the SRK/T and Hoffer Q formulas, the one-piece IOL group differed significantly from the three-piece IOL group
in terms of the MNE obtained 1 month and 2 months after surgery. Across all formulas and time points, there were no significant
differences between the groups in terms of MAE.
Conclusions: There was no significant difference between the different power-calculation formulas. Starting 1 month after surgery,
the three-piece IOL group showed myopic postoperative refraction compared to the predictive spherical equivalent using
the SRK/T and Hoffer Q formulas.
