Abstract Details


To compare the degree of concordance between the measurements obtained with IOL Master 500® (biometer based on Michelson interferometry) and IOL Master 700® (biometer based on optical coherence tomography -OCT-).


Clínica Rementería, Madrid, Spain.


We performed a prospective study of 100 consecutive eyes that underwent cataract surgery. A complete preoperative examination was performed, including biometry based on interferometry (IOL Master 500®) and biometry based on OCT (IOL Master 700®). We compared the measurements of axial length (AL), anterior chamber depth (ACD), keratometry (K1 and K2 readings) and horizontal white-to-white (WTW) distance obtained with both devices. We also evaluated and compared the intraocular lens (IOL) power calculated with both biometers.


Intraclass correlation coefficient (ICC) was moderate between IOL Master 500® and IOL Master 700® for AL (ICC=0.73; P=0.05) and high for ACD (ICC=0.88; P=0.01), K1 reading (ICC=0.96; P=0.001), K2 reading (ICC=0.98; P=0.001) and horizontal WTW distance (ICC=0.91; P=0.001). In 52 eyes (52%) the IOL power calculated with both devices was similar; in 26 eyes (26%) IOL power obtained with IOL Master 500® was 0.50 diopters higher than the value obtained with IOL Master 700® and in 22 eyes the IOL power estimated with IOL Master 500® was 0.50 diopters lower than the IOL power with IOL Master 700®.


Our study suggest that the measurements obtained with IOL Master 500® and IOL Master 700® show a high agreement for the calculation of pseudophakic intraocular lenses.
