- 摘要：Purpose
To evaluate the accuracy of various formulas installed in IOLMaster software which uses partial coherence interferometry for axial length measurement.
MethodsThis retrospective comparative study included 81 eyes of consecutive patients who had uneventful cataract surgery with implantation of Acrysof single piece (SA60AT) IOL. Axial length was measured with IOLMaster and IOL power was calculated using various formulas, including SRK II, SRK/T, Holladay 1, Haigis, and Hoffer Q. Subjects were stratified by axial length into Groups A (axial length < 23.50 mm), B (23.50 mm ≤ axial length < 25.00 mm), and C (axial length ≥ 25.00 mm). Target refractions of the five formulas were compared to the postoperative manifest refraction at 1 month.
ResultsThe five formulas showed no difference in predicting postoperative refractive errors among all of the groups.
ConclusionsFive formulas installed in IOLMaster software provided equivalent predictions of postoperative refractive error regardless of axial length.
